Default 5.7 L Hemi Electronic Throttle Problem?

Today my Hemi died twice while driving after issuing an electronic throttle warning on the dash. I installed a cold air induction this weekend, and I think that the increased air flow with the stock exhaust may be causing excessive heat and / or back-pressure, giving me this problem. The new air induction worked great for a day or two, noticable power gain and a nice throaty rumble from up front. Any input?

Default RE: 5.7 L Hemi Electronic Throttle Problem?

I bought a 2004 Durango with the 5.7 Hemi in it and it began experiencing some of the ETC problems. Bad idle, heavy RPM's on startup. We received a Recall notice on our Durango about a Capacitor under the dash that was faulty and could have caused a dash fire. I went to the dealer and talked to them about both the problems. Once they replaced the capacitor, it eliminated the Electronic Throttle Control problem also.

Just a thought..

The intake will not increase back pressure. This is impossible, the exhaust is already free flowing, and no intake could cause a bottleneck. The engine only needs so much air to begin with, and can't use "extra" air to increase back pressure. Your issue is a common problem with the Hemi. Take it in to your dealer for a computer "flash" or re-programming.

I have a 2005 Ram 1500 that needs a EGR Valve. Could that be causing my ETC Light to flash?

Default 05 dodge electronic throttle problems

I own a 2005 dodge ram hemi. It seemed to hesitate when you first started it up and then put it in drive it wouldn't go for a second and then would pick up. Felt like it was out of tranny fluid. Then it died on my wife. Got it to start back up and the etc light was flashing had irregular idle and had to limp it home with no throttle. It only has 63,000 on it and the dealer was saying it was the throttle body or the pedal assembly. I just couldn't believe that the parts would have failed already with the low mileage. I Investigated it myself and found that on the left side of the engine (when sitting in drivers seat) at the back of the fuel rail the electrical connector closest to the fire wall was laying against the fuel line. Upon further inspection i found that the pink wire with the yellow stripe had rubbed on the fuel line to bare wire. I fixed it with a pink or samon colored heat shrink butt connector, and then taped the wire loom up real good. Problem fixed! I could imagine that this is a common problem due to the connector location, and considering the dodge wiring harness isn't covered with wire loom like other manufacturers, which makes the wires more suseptable to damage. Hope this helps someone it saved me a ton of headache and money! God bless! With prayer, and faith ne thing is possible!

Default electronic throotle control light

I have a 2004 dodge ram 1500 w/ the hemi . I have a problem but only on long trips.After driving a long time the etc (electronic throttle control) light comes on and performance is terrible. I then must pull over disconnect the battery cables to reset the computer , and then it is fine. this only happens when we go on vacation. related to multiple hours of continuous driving. never happens driving locally. Is it the tps(throttle positioning sensor), or is something else causing the senor to turn the dash light on.had it hooked to a scope today, but there are no faulty readings, tech said its probably because i reset the computer. Please help, thanks ,Tim

p.s. has done this the last 3 years of trips. but i dont want to push my luck and have it go totally out

You need to scan for codes the next time it happens. Then you will know where to look.

I have put a 2005 truck 5.7 hemi in a cj7. It has a 4500 manual tranny behind it. Last year I would lose my gas pedal when I would drive it all day in both off roads and on road conditions. I have replaced the throttle body and pedal and it still did it. Would this be a ecm problem. I would have to turn the key off and restart it and it would be fine until the next time. When it did it the first time I was at a event in Denver Colorado and I took it to a jeep dealer and he scanned it and didnt see any codes that would be indictive of a problem. Does any one have any ideas as where to look. Im about ready to get a new ecm for this. As the previous post it is a bit unnerving to have this happen in the mountains or on the highway. Thanks for any help

added to the previous post, the engine would never die it would just idle until I restarted it.

Could be a bad connection somewhere and it loses a signal just long enough to default to idle or possibly the PCM. You might check all of the pins in the PCM plug for corrosion and or bent/pushed back pins.

You can just turn the key on and off 3 times fast to get the codes in the odometer.

I had the same problem.... vehicle shuddered, performance went downhill. Never have figured out what the problem was. It finally cleared up on it's own.

Also had the problem with it seeming like the tranny was low on fluid.

Codes P-2175 and P-2106 were displayed indicating air restriction and MAP sensor failure. It also stated that the TPS failed. I find out later that my 2003 Ram 1500 Hemi does not have a TPS. No restriction found in air box or anywhere in front of the throat of the intake.

Are there no fixes for these problems?

Sorry to bring up an old post but after doing some searching on the internet and finding multiple possible causes for this problem I saw the above post and thought to myself, "ahh... there is no way that it could be that".

Well guess what? That IS exactly what happened to my truck!

Damn squirrles! The squirrel didn't actually make a nest, not yet, but it did leave a few acorns on top of the intake manifold for me to clean up.

Of course the stupid squirrel had to chew through two wires leading to the throttle which caused the idle to surge about a thousand rpm up and down.

I soldered the wires back together and sealed it back up with electrical tape and all is good now

Just thought I would share my story with everyone because I guess you never know what can happen

Default ETC problem on long trips

I have a 2003 dodge ram 1500 w/ the hemi. I have a problem but only on long trips. After driving a long time the etc (electronic throttle control) light comes on and performance is terrible. I then must pull over disconnect the battery cables to reset the computer , and then it is fine. This only happens when I go on long trips with multiple hours of continuous driving. Never happens driving locally. I can't hook it up to a computer reader because I am usually a long ways from home. It has done this on every long trip for a while now with no lasting affects, but I dont want to push my luck and have it go totally out. Someone else had had the exact same problem and posted on here a few years ago, but I didn't see an answer. Any suggestions? Anyone else have the same problem and find a solution?
