Let's see where this thread goes but people w/ ETC know that it can be a pain in the rear sometimes since it's computer controlled.
I've come up with some ways of "manipulating" it's settings for better throttle response and better driving conditions.
If you have you're foot completely off the gas then punch it, nothing will happen for two seconds .. kinda dangerous if you're trying to pull into traffic or make an emergency lane change.. I've found that even the lightest pressure on the pedal tells the computer to respond faster... like if you're maintaing your speed and punch it, the Jeep will react faster than not already having your foot on the pedal.
And downshifting.. try downshifting without touching the brakes. Each gear clucks into the next but if you have light pressure on the brake pedal, the computer reacts differently and makes for much smoother downshifts. Safter IMO and more controllable.
This is me thinking out loud, so talk it over.. have you tried these methods? Are there any other ways to make ETC easier to deal with? Discuss and we'll see where this goes...
For all that may want he info, I just got the call from the Jeep Stealership. (I mean that literally, you'll see why) they say its the Throttle Body, $450 with labor. Thats life I guess. About my "stealership" comment, they also said the throttle body failure flooded the plugs...please sit down... $484 for plugs and labor in addition to the $450 for the throttle body.. that $30 a plug. I do my own maintenance, NGK's cost me about $60 for the set and about an hour to change. And they wonder how they get a a bad reputation. I will update again if it turns out to be something other than the throttle body. Thanks !!
YEs , I know. The throttle body from Jeep is $190 and what, 4 or 5 screws. With the tow bill and the "traditional" $100 diagnostic I'm in for $200 already. My concern is the plug change. I told them no to the plugs, so if it doesnt run with the new throttle body I will here that its the plugs.
Followed your tutorial a couple days ago, I'm pretty sure I noticed a big difference, mostly when slowing down for a turn, taking the turn, then when getting back on the throttle it used to take 40 years for the gas to kick in, now it's not nearly as bad. thanks man
Thanks. I couldnt be sure it was the throttle body so I didnt want to start to just change parts. I dont believe the plugs are bad either. The Jeep ran one minute and the wouldnt start the next. No chance for the plugs to foul to the entent there gone. I will know soon enough.
The stealership must have a bad crack habit they need to fund to be charging those prices! You could have purchased a nice 85mm Arrington TB for 499.
As for the Electronic Throttle Control....I say it's crap! I am not to fond of suggesting to the engine that I would like to go fast and then having it decide what it wants to do or not do.
Some of the guys with Rams that have swapped a 5.7 into their 4.7 trucks have been utilizing their 4.7 PCM/harness with a Mopar Performance cable driven throttle body made for the Hemi.
I am wondering if there is provisions within the 5.7 harness to splice in the sensors that a 4.7 would normally use, and swap in a 4.7 PCM?
UPDATE: Picked the Jeep up today, started right up-just like old times. $435 lighter and heavy one new Throttle Body. Drove about 5 miles and stopped off to pay my auto insurance. Came out of the office and no start. Same condition and MIL's as before. Back on a wrecker and back to the stealership. I knew this was gonna be BAD.............
I Just wanted to state I am not trying to hijack the thread. Since I was having the ETC light come on it might be relevant to Electronic Control problems. If its an issue I will make this my last update on my ETC issue. As stated earlier, after picking up the Jeep at the stealship, it broke down about 5 miles with the same issue. Another tow to the stealer and they called today. Its seems now it needs a PCM. $725.00. on top or the $424 for the throttle body they still claim I needed. They still are complaining I didnt get the $484 plugs.
so even the people at the dealership don't know what the hell they are doing? OMG, who are we gonna entrust our Jeeps with in this world but our JeepBroz... Best Wishes bro!
Hey guys my Jeep just got out from the dealer yesterday because of this problem. It is solve and i was happy, for 3 months they had bin looking for the issue and they finally found it. The things they replaced are kinda pricy (new gas pedal), (accelerator), ( Electronic throttle control sensor), and last but most expensive one is they changed the computer system that is located on the right buttom hood of the fron car where those four slots located. Now i could finally breath!!!
My 2007 jeep commander will not start and the electronic throttle control keeps showing up plus my battery,alternator, and starter are all good. How do I fix this problem
I've never seen nor heard of the vehicle not starting because of the ETC, but I've seen them be hazardous to drive because of uncommanded surging, erratic operation and stalling. They've always restarted though.
Do you have some DTC letter/numbers for us? Any further background....recent other work performed, what all you've done so far, will it crank over, how do you know all of the components you listed are good, etc.?
When I turn the key over it does nothing but click. Plus I tried giving it a jump a few minutes ago and it did nothing, and all of my lights work just fine they're not dim or anything. The electronic throttle control light is the only light that's coming in the dash once I try to start my car and then it's saying transmission over temp
How many miles on it? How old is the battery? Do you have a code reader, so you can see what DTC's have been set? I'd check the easy stuff first, in approximately this order:
---DTC's with a code reader. Post them here.
---Check the battery, preferably both with a conductance tester and a load tester. This will confirm, with certainty, the battery condition. Also, check the terminals for corrosion and good connections. After a load test, the battery should be recharged overnight. Note: The slightest battery problem with an all electronically, computer controlled vehicle (all of them are now) can and will cause all kinds of issues, with many of them being erroneous.
---Swap the Starter Relay with the A/C Clutch Relay. They're side by side. See if it starts.
---Swap the HVAC Relay with the Automatic Shutdown (ASD) Relay. See if it starts.
---Check the wiring at the starter, especially the yellow wire. These have been known to fail.
This will eliminate a few things. Let us know the results of all this. If none of them resolve your problem, it may be the starter or ???
agreed, I'm curious of the dtc's myself. I have had a throttle body fail too in the past from moisture getting in it (somehow) created a surge issue on part throttle and occasionally put the jeep into limp mode which forced me to restart it
My vehicle will not start, i figured out that its not the etc but its computer malfunctioning. We i try to start the vehicle the etc, oil light, and the battery stays on for about 30 secs and goes off but then the engine light blinks letting me know that its the computer malfunctioning
I have a 2017 Grand Cherokee Trailhawk 5.7 hemi. Has anyone had this problem? We were driving and started to slow down at red light, Electronic Throttle Control Warning came up on screen, the JEEP dropped down into about idle speed only, it would not speed up. I finally got to side of road, only way I fixed it was shut down and restart. It ran fine then until slowing down again after about 15 miles, it did the same thing. The other day I took it to Dealership, they didn't find any codes and said the checkout system they were using said the reason might have been by having your foot on the gas petal and brake petal at the same time! This sounded kind of made up to me, has anyone hear of this problem? Sorry about the long note. Thanks!
On the earlier models Hemi's that would be a throttle body problem. Don't know if the newer ones are the same or not. Any other symptoms.....surging, erratic idle, poor throttle response, mushy pedal, etc.?
No, this is the only problem I had with it, the Throttle seems to pick up very good. I guess I'll just have to drive it some more until it quits! It only has about 400 miles on it. Thanks for trying to help.
