Default Problem with PT Cruiser 2.4l Turbo

Hi there ,

I'am from Germany and I'am new at the forum. I own two PT's and a Dodge Ram. Since some days I have a problem with my 2.4L Turbo PT. If I accelerate gently the PT is going well - if I speed ​​up abruptly, the engine light comes on and the engine shut of. This happens at any speed when I press the accelerator pedal fully through (10mph - 80mph). Due to the short off there is a strong jolt. If it goes badly it shut of completly down and not only has a misfire and you can just roll out. Same problem occurs even when the engine is running slow in a high gear the engine shut of. Does anyone have an idea what could it be? The error memory is empty. But in the moment the engine shuts of the engine light burn. Could it be a sensor, turbo or the engine control unit? I changed the spark plugs, ingnition wires and the coil and the throttle sensor.

Thanks and regards,
IFG

Welcome to the forum. You say the "error memory is empty" but how was it checked? Was a scanner hooked up to the computer port to investigate any stored errors/faults ?

IFG, disconnect the battery for 10 or 15 minutes, re-connect the battery and try driving again. This will reset the computer. Funny that there were no codes after the engine light came on. Check to make sure all the ground wires are clean and firmly mounted. Check to insure all vacuum lines are attached, and the hose clamps from the turbo to the innercooler and throttle body. Some times it's something simple! Good luck.

I disconnected the battery for 15 minutes, re-connect the battery and try driving again. Same like before. Now I checked all hoses and they are all OK. Could it be a Problem with the air charge temperature sensor?

Thank you for your support.

Hi,

it was the Intake air temperature sensor (IAT sensor). Now the PT runs fine again.

Regards,

The procedure of disconnecting the battery will reset your Radio stations not your ECU!
Bad idea with PT Cruisers.

This is because disconnecting the battery does nothing to restset anything except the dash engine light the DTC are still active until the engine cycles and clear the readines file.

Good that you got it running.

Maybe it is time to invest in an inexpensive Diagnostic scanning tool if you plan on keep in the PT Cruiser and trying to work on solving any issues ECU related that may come up in the future.

Hi,

it wasn't the Intake air temperature sensor (IAT sensor). After two weeks I had the same problems. I bring the PT to a local repair shop.

Last Saturday I become the car back (after a half year). Same problems like before

I made a short Video on YouTube. Can anyone help me?

There is no messages in the error memory. They checked it with the genuine Chrysler and with a Snap On diagnostic computer.

Best,
Immo
