Dodge Caliber ETC light comes on, the car bucks and loses acceleration

2011 Dodge Caliber ETC light comes ON

Car bucks and loses Acceleration

Q: 2011 Dodge Caliber. The ETC light comes on, the car bucks and loses acceleration.

A: This seems to be a common problem in the Caliber.

Correctly repairing the problem will require diagnosing it. There are few possibilities that can cause such problem.When the ETC light comes on it is because the powertrain control module (PCM) has seen a problem somewhere that affects it's ability to control engine RPM and it sets a fault code.

Troubleshooting has to go step by step.The first step in diagnosing the problem is seeing what fault codes are stored from there, an accurate diagnosis will most likely require some testing to be done at the time it is acting up.

As per the problem described it seems that issue is bad MAP sensor, throttle body, a vacuum leak, wiring, the PCM itself, etc. It sounds like the engine is going into limp-in, which often happens when the PCM sees a problem on either the throttle body's TPS or drive motor circuits. I've seen a handful of throttle body failures on these cars, there's a good chance that is what your car needs.

Any professional garage shop should be able to diagnose and repair the problem. If it does need a throttle body then it will most likely need to come from a dealer,because  aftermarket will not carry a replacement for throttle body.

2003 Dodge Ram: Faulty PCM no start?

The vehicle is not starting.There are many possibilities for this types of problem.
But if all checked ok,then its issue with the brain that cause no start problem.PCM means the brain of the vehicle.Also known as power control module.

Check the fuses,the ignition relay and other relays in fuse box.

If check engine light is ON,then scan for error codes.If no codes are coming up then PCM can be the issue.


To confirm the PCM is faulty, it can only be checked when the vehicle dies and wont start and doesnt make a sound.

On the PCM, there are 3 connectors - white, grey, black.

On the black connector, first back probe the dark green with black stripe wire at connecter terminal #22 for power. If no power, then it is being lost between the battery and the PCM.

If power, then check terminal #2, light green with black stripe for 12v going out. If 12v not present, then replace the PCM.

If 12v present, then  check for 12v at the ignition switch

1997 Chevrolet Cavalier will not start and keep blowing the cls/pcm fuse?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.

This is rare problem,but noticed by few Chevy users.The car will not start and has no spark,when the clutch is pushed the CLS /PCM fuse blows out.


That fuse that kept blowing is a direct wire to the PCM. Below is a picture of one of the connectors at the PCM. I have marked the pin number that you need to check. Make sure you're getting power at that pin number (it's a pink wire). Also below is a picture of a main ground for the circuit that the fuse was blowing. Also is a picture of the connector that that ground wire goes through. It's a black and white wire. Also I see you said you got a new computer. Did you have it or was it flashed for your vehicle ?






Sounds like pcm or wiring has a short causing fuse to blow. Maybe try another pcm.
You could also remove the alternator and have it bench tested at autozone or advance auto parts or your local auto parts store. This will tell you if the alternator is blown.This details will help.
Thanks.
