CEL with 4 codes. Please help!

Hey guys, let me give a little run down before I get into the issue. My wife's jeep is a 05 5.7 limited, 80k miles. Runs great. Last summer I put a crankshaft position sensor, camshaft position sensor,egr valve and a few other things on the jeep as preventive maintenance as I had heard they were common problems on these jeeps and I wanted to get ahead of the curve.

A couple months ago I had to re-replace the egr valve as it had already failed (whatever advance auto parts carried... I believe car quest brand).

Ok on to the problem. My wife went to start her jeep yesterday and it took a couple seconds of cranking before it fired up. She drove a few minutes and noticed the check engine light was on. She drove it home about 15 minutes and parked it. It was still running fine without issues aside from the check engine light being on. No knocking or anything either.

Did the key on/off truck and pulled up the trouble code message display and got 4 codes out of it.

The codes are as follows p0340 , p0016 , p0325 , p0330 . All of which appear to have to do with either knock sensor,crankshaft sensor, camshaft sensor.

Does anyone have any idea what would trigger these 4 codes to kick at once and toss a check engine light?. And what would cause the codes but seemingly no noticeable changes in how the engine runs/performs.

Only thing I can think of is either the crankshaft sensor or camshaft sensor I installed last summer is faulty and causing issue (judging by the track record of the egr valves advance auto parts sells I wouldn't rule it out).. The only thing that makes me second guess that is that there are 4 trouble codes. So is it possible that 1 of the sensors is at fault and could trigger a chain reaction of fault codes in sensors that are not faulty?. Are the sensors tied together in such a way that when one has a fault that it triggers the others to act up or throw a code as well.

if any of you could shed some light on the subject I would really appreciate it. Thank you in advance!.

Re: CEL with 4 codes. Please help!

Normally, I would say a timing belt issue would lead to both cam and crank shaft sensor codes...however I believe the 5.7 uses a chain and with it being an interference engine you would certainly know if the chain had snapped!

Not really sure what to think...if you clear the codes do they come back straight away?

Re: CEL with 4 codes. Please help!

I have not tried clearing the codes yet.

A little more details on the issue.

It takes about 10 seconds of cranking before it starts. Every time.

I took it for a test drive and it seemed to run fine. Maybe a slight hesitation under acceleration but not bad. I got on it a few times testing it out and it kicked down and sped up as usual under hard acceleration. Then about 5 minutes later it would no longer "kick down" under full throttle. And even from a stop if you floored it it would take off sluggishly and shifted weird.

Like it went into some sort of "limp mode". I brought it back home and parked it and checked codes again and there were no new codes. Still the same 4 codes.

Throughout all of this nothing sounded off. It still purred like a kitten, all gauges were within normal range. Idled smoothly. Very odd.
If anyone else has any input on this is greatly appreciate it. Definitely not a snapped chain or anything though. I agree.

Re: CEL with 4 codes. Please help!

I would first clear the codes and run the engine, to see if they all come back.
I donīt see the relation between the knock sensor codes and the cam sensor. But i would check the wire bundles under the hood for any effidence of chaving or rubbing.
If knock is detected, the PCM will retard the ignition timing. This will reduce the engine power. But the knock sensors are not used during starting, so would not explain the extended cranking time.
But due to the P0340 and P0016 codes, i would first suspect the cam sensor or its wiring.

Re: CEL with 4 codes. Please help!

I hope to mess with it this weekend and see if I can figure out whats going on . ( I am pretty sure I saved the old cam and crank sensors which were still good. If I can find them I will use them to trouble shoot).

My gut is telling me its a fault with the cam sensor. Only problem is I am confused on why all of the other codes came up aswell. Which is why I was hoping someone could tell me rather or not those sensors are somehow tied to one another and when 1 throws a fault it sends a chain reaction domino effect and throws codes for various other sensors within that "chain".

From my understandings the codes are as follows.

code p0340 Camshaft Position Sensor Circuit Bank 1 Sensor 1 No Cam Signal At PCM

code p0016 Crankshaft Position - Camshaft Position - Correlation Bank 1 - Sensor A.

code p0325 Knock Sensor 1 Circuit (Bank 1 or Single Sensor)
Knock sensor (# 1) signal above or below minimum acceptable threshold voltage at particular engine speeds.

code P0330 Knock Sensor 2 Circuit (Bank 2)
Circuit Knock sensor (# 2) signal above or below minimum acceptable threshold voltage at particular engine speeds.

which is strange that they would all go off at once like that as I find it hard to believe they all failed at the exact same time. I can confirm that it wasnt but a few weeks ago i showed my wife how to check for trouble codes on her own and that there were zero codes at that point in time. And there has been no hiccups or check engine lights leading up to this. Just all of it all at once decided to act up.

In the mean time before I have a chance to look it over real good. If anyone else has had a similar issue or knows if there could be a chain reaction happening etc...etc.. I would appreciate the input. Thanks

Re: CEL with 4 codes. Please help!

Electrically wise there is no direct connection between the knock sensors and the cam sensor. The knock sensors are connected directly to the PCM, as the cam sensor is as well. All three sensors though are used by the PCM to set the ignition timing or to retard the timing (in case of knock).
Maybe, and i only say maybe, the cam sensor sends a wrong cam position signal (causing the P0340 and P0016), which causes wrong ignition timing and knock as a consequence.
The function of the knock sensors can be tested by hitting with a rubber or wooden hammer a part of the engine close to each sensor, with the engine running in idle, the rpm should change a bit. Take care of the moving part when doing this.

Re: CEL with 4 codes. Please help!

I see what you are saying. Still confused as to why it also threw a crank sensor code as well though.

I would think its not a wiring issue as it has no water damage issues, no rodent issues and has low miles and has been well maintained and I recently inspected inder the hood and didn't notice anything. Then again I have heard of even new Chrysler products with even less miles having wiring issues due to chaffing . So stranger things have happened.

So long to the good ole days of the carburetor haha.

Re: CEL with 4 codes. Please help!

:UPDATE:

So, today before going to families for Easter dinner I unhooked the battery on the Jeep and let it discharge for a couple hours while I was gone. Got home and hooked the battery back up. Initial start up was still a 10 second long crank before it fired. Check engine light came right back on. I drove it around the block and parked it.

I ran the DTC report again and this time only came up with 1 code (P0340-cam sensor). So I took the sensor out of the engine and noticed some slight scrape marks at the end of the metal "pick up" on the end of the sensor like it was coming in contact with the cam. I sat it side by side with the original cam sensor (the one I took out last summer that was still good) and in fact the "new" sensor was SLIGHTLY longer by about maybe a 1/32".

rather that had to due with the sensor failing or something else I am unsure but I know it was not right. And this was BWD brand. so anyone out there getting replacements be sure to check the length just in case so you don't end up with a larger part like I did.

Anyways, put the original cam sensor back in. and she fired right up. no check engine lights, no extended cranking. runs great. Thanks to those that chimed in with ideas and suggestions.

apparently when a cam sensor goes out it can in fact trigger crank and knock sensors to throw codes aswell.

I hope this thread will be useful to someone in the future.

Re: CEL with 4 codes. Please help!

Just for the records, you didnīt have a crank position sensor code. The P0016 was a correlation between the cam sensor position and the crank sensor position. If there is a certain difference in the position of both signals (it will compare the position of the crank to the cam), it will set that code.
Good that the problem is solved, happy jeeping.

I asked in the beginning of the thread if/why it would be possible that the crank sensor code was triggered in a chain reaction caused by a cam senor failure and didn't get an explanation. Sorry. Thanks for clearing that up though. All is good now. hopefully if anyone else has a similar issue like this one they will bump into the thread and they can get it fixed quicker.

Re: CEL with 4 codes. Please help!

I have the p0325 and p0330 code that popped up today and i'm wondering if I have the same problem. I am experiencing a lot of power loss, and the jeep feels like it wants to die on me at idle sometimes. I also can hear a little knock too.

When I think about it a few months ago I replaced the cam position sensor with one from Auto zone, Do you think this could be my problem?
