I am on my secong go round. First time it cost me 600 bucks and a new PCM under warranty. Was good for a couple hundred mlies. Back again. This time they put in a new gas pedal and some transmission part. They were all kinds of confident. That was Wednesday, called Saturday and it still is no good and they have no answers.

Just had the same problem yesterday

I've got a 2007 Dodge Ram 1500 Big Horn with the 5.7L hemi in it.

I was sitting at an intersection, my truck made a "clunk" sound, then the engine shut off. I noticed the ETC light flashing. I restarted it, and it was really rough. I managed to get off the road, and pull into a parking lot where I turned the key off to look up the light in the manual.


I was close to an Oreilley's auto parts, so I figured I'd try to make it there to have it code scanned.


It started up just fine, and the ETC light shut off, but now my check engine light was on.


The only code they got was P0522 - Engine oil pressure sensor circuit: Low Voltage


Nothing at all about the ETC. I drove it fine after that, tho I was a tad bit low on gas (about 1/8" tank). After finishing my errands, I stopped and got gas, started the truck up, and then the check engine light was off.



My buddy has a higher-end scanner, and he's going to check history codes for me today. I just found this thread, so wanted to post my experience here as well.

My buddy who's a mechanic says he's seen this problem before with these trucks. He came over and read the codes and looked thru the computer in the truck. From the codes he saw, he's thinking that the plastic portion of the oil sensor may be leaking oil and short-circuiting the sensor. Once I get my other car back, i'll take this in and have them put it on the hoist and check that sensor.

my 2016 power wagon lost throttle control the other day pulling out from a side street onto a main road . It was after a rain storm when the traction control symbol lit up and just that quick got message on the evic service electronic throttle. I lost all throttle control for at least two minutes and during this I was almost rearended twice. I took it to the closet dealer who pulled a brake throttle module code stored but not active. I am very upset with this and my servicing dealer was called the next day, they are closed at 5 pm on a weekday , to make an appointment when I could get the truck in . I set it up up for a Monday and told the service worker I would need a vehicle to drive and that I would drop off on Saturday before. The service person told me no problem to have a car on Saturday , I took the truck in to drop off and no loaner as promised. I am at this point looking into what my rights are as an owner and if legal action can be brought against ram and Fca for unsafe vehicles. This is only at 17,500 miles.

Did you file a report with the NHTSA?

For any sort of unsafe vehicle condition, that is the way to go about it. If you go to FCA they'll probably treat it like a regular warranty type issue

Thunderhorse , you are correct on Fca , they probably won't even acknowledge this happened. I know that from previous dealings, I have lifters starting to fail and the dealer tells me run it till it breaks so they can find the problem and Ram agrees that is the best policy.

Well they also have to have some sort of actionable justification to induct the truck too. Unfortunately the techs these days seem to get less diagnostic training for anything that doesn't involve a code reader.


How do you know you have failing lifters, did you pull the valve covers or its just making sounds you don't expect?

The top end of the engine has a metallic rattle on the passenger side in the vicinity of cylider#4 and #6 . It sound very similar on startup when the lifters bleed down overnight. When the noise happens it will change pitch as the engine is revved up to around 2000 rpms. I have had other makes of engines exhibit the same noises and they were all lifter related , also history of these Mds engines and lifter issues this is not uncommon.

MDS has absolutely nothing to do with lifter failures, it happens on non MDS holes and non MDS engines

true, but from what I have seen it is more common on the Mds equipped models, I had a 2006 2500 with a 5.7 110000 miles on never had a problem with bleed down or noise like this one. It is a bit disturbing paying $50K+ for a vehicle , pulling into a place and have people ask if you have diesel in the truck because it sounds like one.

The 04-08 Hemis had issues with valve seats; the 09+ Eagles are the ones with the lifter issues. Its not more common on MDS models, they've had MDS since 2006 and it wasn't an issue until the Eagle Hemi was released in 09.


FWIW the HDs with the 5.7 do not have MDS. There are a lot more 1500 Hemis than HD 5.7s though

Electronic Throttle Control (ETC

Hello everyone
06 Ram 1500 Hemi 2x4
I have had this same trouble with my dodge as many of you have ETC light comes on and loss of throttle most of the time with a code for Maps and camshaft position sensor and sometimes others codes and trying to get a dealer to fix is like pulling teeth and wire diagrams are hard to find so I took some time to look in to what was going on with the wiring and this is what a came up with I really hope this helps some of you out as your posts did help me when I could not find anyone not trying to get 200 to 1000 in diagnostics without a guarantee to fix .The dodge uses a 5v power supply to run all the sensor like most new car do it’s an OBDII thing but dodge use’s one 5v for all of them everyone and your (ETC) same 5v supply if anyone of your sensor go’s bad or in my case water in one of the elects connectors you get some crazy code for air temp EGR O2 you get the point. But keep in mind it can be a bad wire or bad ECU(PCM) So for the testing let's keep it simple .
1. Key off remove your Maps sensor connector or whatever 3 wire sensor code you are tripping looking at the end of your connector with the locking clip up from left to right the pins are 1 2 3
2. You will need to ohm out from pin one to pin two if you show resistance of any kind this is going to help you. Keep looking at the resistance
3. Now pull the 4 elects connectors of you ECU(PCM) off
4. Do you have resistance Yes or No
5. If No stop and replace your ECU (PCM)
6. If yes start unplugging your sensors one by one when you an open line (no reading)on your ohm meter sometimes seen as (1.0000) you have found the troublesome sensor replace or clean it as needed.
Now my pickup just had water in the transmission pressure sensor connector and that had the whole pickup down. And remember every 3 wire sensor on your dodge is using that 5 v power supply you may have to look at all of them .
I hope this is some help to you all Good luck.

Thank you for this hoping to test sensors soon
