Hello and welcome to just answer. I have seen where the throttle body itself can get bound up and cause this issue. If the TPS ( Throttle Position Sensor ) in the throttle body does not see a voltage change when you step on the throttle, then 5hat light will come on and force the PCM to go into limp in. Inspect the harness and connector at the throttle body. Wipe down the inside of the throttle body with a throttle body cleaner sprayed on a rag. If the problem continues, then I suggest replacing the throttle body. We see this at the dealer where I work. I hope that this information is helpful and please let me know if you need further assistance.
Hmmmm, the throttle blade may be sticking open at atart up and that can cause the high idle and ETC light. The TPS voltage can be checked using the sensor display menu on your scan tool. The TPS voltage should transition smoothly as you step on the throttle. If it is jumpy ot glitchy, then replace the throttle body. Is it the ECM ? well maybe, but based on your description of the symptoms, I do not feel as though it is the ECM/PCM.
I hope that helps,
The intake air temp sensor probably is not causing the ETC light, but I could see the EGR valve causing this. You may want to try an OEM Mopar valve if the problem continues.
Hello, just checking back to see how it is going with the Durango.
Gotcha. If it acts up again, go with the throttle body next, then the EGR valve would be the next step.
