    Company said possibly because I disconnected battery when installing it I fried it, so they are sending a new one. That doesn't make sense to me but ok, so I sent theirs back and put my old one back in, car runs fine, just constant check engine light and I'm trying to get it turned off to sell it

    Battery static voltage is 12.5v, charging at 14.1v all is ok, I'm baffled, I called the company I got the new ECM from and told them, and they are sending me another new one so hopefully that will work, otherwise I don't know what else to do. I checked the voltage at ECM, less than .2 volt drop to both key on and constant power and both grounds are good.

SOURCE: Change the thermostat on 2002 Chrysler PT Cruiser

Hi, i have put together a step by step guide that will help you with this replacement job. Make sure the vehicle is in a cool state before starting this job.


* Drain some coolant into a clean container until the coolant level is below the thermostat housing.
* Remove the upper radiator hose connection from the thermostat housing.
* Loosen the housing bolts and remove the housing.
* Remove the gasket and scrape it carefully from the surface of the housing and the mounting surface on the engine. If the gasket remains on either of the surfaces, there will probably bea coolant leak after reassembly. Some engines use a rubber O-ring to seal a thermostat housing.
* Compare the size of the thermostat to the old one. They are of different sizes, types, and temperature ratings.
* The temperature rating is stamped on the sensing bulb on the bottom of the thermostat. The temperature bulb faces the block.
* When replacing a thermostat, be sure that the thermostat fits into the groove in the block or outlet housing. If the thermostat is installed upside down, the engine will overheat.
* Install the gasket.
* Reinstall the thermostat housing. Refill the system and run the engine or pressure test to check for leaks.
* When the engine has reached operating temperature make sure the thermostat opens.
* You should be able to see coolant circulating within the radiator.
* Another way of checking thermostat operation is to feel the top of the radiator hose or use a thermometer or multimeter with a temperature probe to confirm that the coolant is warming up.
* If the engine is overheating, but the top hose is still cool to the touch, the thermostat is stuck closed and must be replaced.

NOTE
When a paper gasket is used and the recess is in the thermostat housing, it is a good practice to position the thermostat into the recess and glue the gasket to hold it in place. If it falls out of its groove during installation, the outlet housing can be cracked or a coolant leak will result. Before tightening the water outlet housing, try to rock it back and forth to be sure it is flush. Housings are often cracked during this step.

SOURCE: fog lights came on; can't turn them off

1.At first take out the foglight's fuse before you battery is dead. (Fog lights stays "ON" even you leave the car).

2.You must replace the Multifunction control switch =(

Here is the photo of problem:
http://www.ptcruiser.fi/ptgalleria/albums/userpics/10010/normal_sumuvalokytkin.jpg

Fog lights are connected to pin 13,14.
Fog light switch is "B". Because the current is many Amps, contact surfaces are heating up.
After that the contact opening "C" is melting (made of plastic) so the fog light stays "ON".

SOURCE: "Check Engine light"

The issue is that the system randomly checks the loop of the fuel system to confirm that it has no leaks. A missing cap is the easy one to correct. It might also be a slpit in the rubber hose that connects the fuel fill tube (on the chassis) to the one on the tank, or any other hose in the the entire fuel delivery/ fume recovery sysrtem. The solenoid that allows the engine's vacuum to be used to conduct this test can also be sticking so that after the test cycle, it doesn't reclose. Good luck

How do I get code p0601 out.have done everything unhooked battery,cleaned all ground wires.my car will not start.changed battery a cam scencor


code p 0601 refers to engine control module ( ECM) memory check sum error ===causes--- ECM

removing the battery can corrupt the CPU program of the ecm and while if can work in some instances there are many cases where other problems are created by that method
Try substituting a know good ECM if the reset fails

The ECU is not reading the chip in the key. Replacing the ECU will not solve the problem. It is an input issue(signal to ECU) not an output issue ( signal from ECU). Perform an OBDII scan of stored fault history. Probably an ignition switch problem.

How can i check the celenoide on 2002 pt cruiser


I can only assume that you made an unintentional error with you spelling of 'celenoide' the way i would spell it is sellinode. An electrical device that permits the electric starting motor to engage with the propulsion engine of the car. This device is built in the small electric starting motor and can only be checked by downloading fault codes from the ECM

Car has code P0601, we just had the timing belt replaced. I know this is a check sum error. Does PCM have to be replaced?


P0601 means PCM Internal Controller Failur

It just needs to be troubleshooted and if found to be bad, a replacement might be necessary.

Good luck and rate this solution.

Can't get 2002 PT to start after replacing plugs and wirekit


Check a haynes manual or online to ensure the wires are running in the correct firing order and each is securely connected. Also, if you have an alarm kill switch on your car, when you reconnected the battery after doing the plugs and wires it may have reset the kill switch. If its cranking but not turning over, then it most likely is the firing order if you didn't change anything else.
