Diesel Particulate Sensor Fix/Replacement

So I had the MIL come on a week ago or so, but didn't think much of it since nothing seemed to have changed with the Jeep. I had to take it in for an oil change and had them check out the MIL as well, which they said came back as an issue with the Diesel Particulate Sensor. The tech was hoping it would be covered under the emissions warranty, but of course sensors aren't. I don't know the exact code that they found so I don't know if it was the P2002 or something different.

Anyways, they quoted me $2100 to get it fixed which....is insane.
My concern here is that with a bad sensor I'm going to stop getting regens, and eventually going to be put into limp mode.

1: Is this something that might be covered under an extended warranty? I'm out of my standard warranty now and was thinking of picking up something from https://www.chryslerwarrantydirect.com/ but don't know if it's worth it without this being covered.

2: Does anyone know how difficult it would be to replace this on my own? I'm fairly mechanically minded, so a little work isn't an issue if I could be pointed in the right direction for instructions/where to buy the sensor.

Thanks
Zach

First, how many miles on your JGC? Unless you have a lot of miles, I have a hard time believing that something that will affect emissions wouldn't be covered under the emissions warranty but certainly could if they consider it a maintenance item. But with all the attention on the diesel emissions questions surrounding FCA, there might be a case made for goodwill because the engine is under emissions scrutiny right now.

My 2014 threw a P0428 code which wound up being a catalytic converter sensor. I was out of warranty and did not purchase an extended warranty. I did not go and verify but read somewhere that extended warranties did not cover exhaust system components.

The "bad sensor" was between the transmission and the chasis therefore the transmission had to be dropped down to access it. The tech had not dealt with the issue before and probably blew the fix and ultimately replaced 4 sensors in all.

1 week and $1,700 later I'm all good. Part of the reason for the high cost was the dealership trying to clean the ash out of the DPF too.

I don't know if any of my issues described above is what you're dealing with but the exhaust sensors sound the same.

That is categorically false. All of the emissions is covered under the 80k mile federally mandated emissions warranty. Your dealer is trying to milk you and I hate when they get away with this shit. Tell your dealer you are contacting the EPA - which they can be fined HEAVILY for. There is no reason they shouldn't be covering this. They might have to eat the cost and file for reimbursement, but that is their problem, not yours

From the 2014 Emissions section of the manual
Emission Warranties Required
By Law
5.1 Federal Emission Warranty
A. Parts Covered for 2 Years or 24,000 Miles
Federal law requires Chrysler Group LLC (Chrysler) to
warrant the following emissions parts for 2 years or
24,000 miles, whichever occurs first. Chrysler covers all
of these parts under the Basic Limited Warranty for
3 years or 36,000 miles, whichever occurs first.
Gas
• Air system controls
• distributor and its components
• electronic fuel injection system, including injector
• evaporative-emission canister and controls
• exhaust manifold
• exhaust gas recirculation valve and control system
• exhaust pipes (between exhaust manifold and catalyst)
• fuel cap and tank assembly, pump, and fuel lines
• ignition coil and ignition module
• intake manifold
• on-board diagnostic-system components
• oxygen sensors
• positive crankcase-ventilation (PCV) valve or orifice
• secondary ignition wires
• spark plugs
• throttle body
• transmission-control module
• vacuum hoses, clamps, and fittings, as well as tubing
used for these components
• vacuum, temperature, altitude, speed, time-sensitive
valves, sensors, and switches used in these components
and systems
Diesel
• Charge air cooler
• crankcase ventilation system
• electronic fuel injection system, including injectors
• exhaust gas recirculation valve & control system
• exhaust manifold
• fuel cap & tank assembly, pump, & fuel lines
• glow plugs
• intake manifold
• mass air flow sensor
• nitrous oxide sensors
• on-board diagnostic-system components
• oxygen sensors

• "particulate matter sensor"

• throttle body
• transmission control module
• turbocharger
• urea (DEF) tank & control system
• vacuum hoses, clamps, & fittings, as well as tubing
used for these components
• vacuum, temperature, altitude, speed, time sensitive
valves, sensors, & switches used in these components

Parts Covered for 8 years or 80,000 miles
If your vehicle has one of the following parts, this
Federal Emission Warranty covers that part for a period
of 8 years or 80,000 miles, whichever occurs first,
calculated from the start of the Basic Limited Warranty
as set forth in Section 2.1(E). The covered parts are:
• catalytic converter
• powertrain control module
• oxidation catalyst/particulate filter assembly - 3.0L
• selective catalytic reduction catalyst assembly - 3.0L

Emission Performance Warranty
This warranty supplements the federal warranty under
5.1. It lasts for 2 years or 24,000 miles on the odometer,
whichever occurs first. If your vehicle has one of the
following parts, catalytic converter and powertrain control
module, this Federal Emission Warranty covers that
part for a period of 8 years or 80,000 miles, whichever
occurs first. These limits are counted from the time when
your Basic Limited Warranty begins under 2.1(E). The
Emission Performance Warranty covers the cost of
repairing or adjusting any components or parts that
might be needed for your vehicle to pass Federal
Emission

It looks to me that the sensors are not covered only the major components of the CAT and power module.

I think CA does have a much longer comprehensive warranty on the entire system...

Would an in effect Maxcare policy cover it?

Check it out. It doesn't appear to mention any exhaust/pollution equipment. However, in the Parts Covered for 8yrs or 80k it does state that the oxidation catalyst/particulate filter ASSEMBLY and SCR Catalyst ASSEMBLY are covered. These as well as the Cat Converter and PCM. Assembly usually means the main part and associated parts. I assume that attached sensors would be part of the "assembly".

That is my mentality on it too. An assembly is an assembly.

My particulate matter sensor was replaced in January at 40,256 miles.
It cost me $637.64 at a Houston dealership.
$304 for the part (68249512-AC sensor pa 14070020), $300 for labor plus $8 for shop supplies, then tax.
I had been driving with the MIL light on for about a month, pretty much all highway, because the light came on the day after an oil change/flash update and I assumed it was a glitch due to the update. Lucky me.

They prob are. But thy have a matrix they put part numbers on to confirm if they are covered or not. FCA is famous for bilking the consumer. Don't bother wasting your breath or blood pressure with Jeep cares. They are going to say "there's nothing we can do." Just pay the $42 and save yourself the headache.

There are good dealerships out there. I have been fortunate to have been serviced by two in my area but that means driving 65 miles to do so.
Will see tomorrow when they address my P245A CEL if I still feel that way about them even with Max Care.
FCA doesn't need more bad press for poor reliability of emissions equipment but if you look the forum over I am seeing more and more related emissions CELs.

Hey all,
I'm having the P24AE check engine light. I have a US spec 15 Eco Diesel but currently stationed in Italy for the Air Force. Getting Jeep to cover the Diesel Particulate Matter Sensor is not working out so I'm trying to do thins on my own. I'm having a problem deciding which is the correct part number:
"6824 9512 AC" part number is what many have said is correct however when I look that up on moparonlineparts.com it gives me part number "6826 1169 AB" as the Diesel Particulate Matter sensor.
Is there a way you can verify which part is correct for my 2015 Overland with the 3.0 diesel? Here is my vin if that helps: 1C4RJFCM3FC796577
There's a $100 plus dollar difference between the two parts as well.


Thanks.

put a turbo back exhaust on it with the DPF delete and GDE tune, rip off the emissions garbage as all it does is cause problems.

EGR delete as well.
Thanks for the input. Not the answer I was looking for but will keep it in mind.

I am out of town so I can't help with the part number the used on my Jeep. Will not be back until Sunday. I can check when I get back and post the number if that helps...
Yes that will be great. I sent a message to moparonlineparts.com and of course they tell me I need to buy the more expensive part which is probably true.

I just got the same code today... Is it still safe to drive with this code or no? Can't get it in to look at it for 8 days.. dealer is crazy busy...

In the end mine only needed a no charge dealer update/reflash and has been performing well ever since... Lucky that, that may have been all it needed...

I reset mine twice and it lasted a month each but then came back. I was not offered a flash update so maybe given mine was 8 months ago or so that they have solved the issue. I can't understand how a flash or reset will heal a failing sensor or maybe the parameters of the sensor for failing were set too tight.
Love to hear how yours works out months from now. If it does it seems like FCA solved my problem by throwing parts at it when a flash might have solved the problem.

I had TSB 18-012-16 done which checks for faulty sensors/components and if not found defective, I believe it then opens up parameters that may have been too tight and triggers CEL needlessly on properly functioning sensors. I drove it while MIL was on and noticed no difference really....
 
#31 ·
An update for my situation that may or may not be helpful. After clearing the P2002 code about a dozen times I finally gave up and brought it to the dealer. There was no difference in performance the whole time, but I was way overdue for New YOrk annual inspection and it would not pass with the code.

Dealership told me that everything checked out except the PM sensor needed to be cleaned. I assume it is clogged with soot? I cannot get any more info about what is actually the root cause. The good part was that since they already replaced the PM sensor a year ago, this visit was free. So I am happy, unless the issue resurfaces....

As it turns out, the code came back. Dealer decided it needed a new DPF. Vehicle could not pass inspection and I needed it to tow my boat on a family vacation. The DPF was back ordered by 3 weeks and the dealer offered zero solutions. Left me with a CEL on and removed the inspection sticker.

Now the part has come in, I have dropped off the jeep on saturday 7/21 and it is still not done. Tomorrow will be 6 days with no vehicle. Zero communication from the dealership, unless I badger them, and then I get BS. This is the second Jeep dealer that could not adequately service this vehicle. The first time it took 4 visits to the shop for them to figure out why it would not start. The DPF replacement is their third attempt at code P2002. If you're reading this because you are considering a diesel jeep, PASS and if yours is running well right now, consider a trade-in.

You have experience with poor dealerships. I don't and think your suggestion is an over reaction because of the way they have serviced your ride.
These dealerships are independently owned and they can operate anyway they want as long as they meet the minimum of FCA requirements.

My guys replaced my SCR in one day, the DPF sensor in one day the EGR cooler and valve once the parts can in which was about 3 days.

So it all depends on what dealership experience you have. Both my dealers have been good but they service a lot of diesel and gas RAMs...
 
#34 ·
Yes I have had bad experiences with 2 of 2 dealerships that have seen my Jeep.

The thing about forums is that they memorialize your words. You have said in different threads that if not for your extended warranty and illegal emissions system modification, you have had too many problems with the vehicle to keep it. Neither of those should be acceptable or necessary to get reliable service out of a vehicle with less than 100k.

I would buy my Jeep again but I had enough experience buying cars to know that the first year diesel and first year 8 spd ZF transmission I would be foolish to not buy an extended service contract.

This is the first service contract or warranty if you will that I have ever bought.

Your complaint is about the dealerships and you seem to not have found one that knows what they are doing.

I don't know if the GDE tune will correct the emission problems that will happen to most of the diesels but if it does I will keep this thing for a long period of time meaning 10-12 years which is what I typically keep a vehicle. The DPF from an engineering perspective is poorly implemented. The SCR on the other hand works well typically and doesn't usually cause problems except if the injector nozzle breaks. FCA did install a guard to stop that from happening to owners but again the 14's have teething problems and I knew that when I bought it.

Again for the record I will keep my ride for at least 8 years or 120K miles which ever comes first. If the GDE tune which doesn't stop the DPF function or the SCR from working solves the EGR problem I will keep it significantly longer.

Suggest you find another dealer and again I only have two where I live one 25 miles away and one 60 miles away and they both have done a terrific job taking care of my ride.

I don't like the piss poor integration of the emissions systems and consider the engine and transmission to be excellent but FCA failed on the emissions.

So I have an update on my P24AE check engine light. The Diesel Particulate sensor arrived and I just had a local shop do the install. It was less than an hour and an easy swap for them. I've since moved from Italy to Belgium and have about 10k miles on the Jeep since the replacement of the sensor and no more code.
