Check Engine Light is on

2002 PT Cruiser,
Check engine light came on about a week ago. I took it to two different major auto parts stores and had them do a free check both came back with Internal Control Module. Neither one could tell me exactly what that means. They didn't give me a code number. I am going to go back and have them do it again so I can get the code number but in the mean time does anyone know right off what this is?

    try having them reset the computer also with the scan tool. Sometimes the ECM will pick up a spike or glitch and kick the light just for the plain reason that it doesn't know what the spike was.

Have you changed your original gas cap. Mine has done this several times and drove me crazy until I changed back to the original cap. I just wanted a lock cap to avoid gas theft, but now if the engine light comes on, I mess with the gas cap first thing (you have to tighten it til it clicks 2 or 3 times) and its not instant. You have to drive it and sometimes wait for 24 hours for the computer to reset. Hope this works for you and avoids a big cost!

My pt cruiser iver heated and the head gasget blew. I was told that I would need to get, at least a new head, if not a new engine becuase the head on this pt cruiser can't not be resurfaced. does anyone...

You may not need an engine depending on how long you drove it overheated. if your engine is not knocking or rapping it may be saveable. check with auto parts stores that resurface engine heads if haveing resurfaced have the head checked for cracks. if you need an engine check your local junk yard for a low milage wreck or look in ebay.

Pt cruiser engine light came on what is wrong? The light is orange and shaped like a little engine. Do i need to just change the oil?

This light tells you that the engine or transmission needs attention. It's not going to blow up if you keep driving it for a little while, if it's still running (red lights, like oil pressure, mean to stop RIGHT NOW).

Just changing the oil is probably not going to make the light go out. The light was turned on by the engine's computer, and indicates that the computer got a bad reading from one (or more) sensors located throughout the engine and transmission. Most auto parts stores can hook up a code reader to your car and read the trouble code stored by your computer. The trouble code indicates what system is not working properly and that may tell you what to replace to fix it. Or it may require more in-depth testing to determine the exact problem.

Check engine light came on

You need to have your vehicle's codes scanned to see what tripped the check engine light. It could be something simple, like a loose gas cap, but there are hundreds of codes that turn on the light, so you need to find out what turned it on to have a clue. Most auto parts stores will scan your car for free, so call around and ask which ones will help you. THey should be able to narrow down your problem for you!

Check engine light on

You can take the car to a parts store like Auto Zone or Napa and they will scan the engine control unit for you free of charge. If the problem is a minor one or one they are familiar with, they might be able to help you fix it right there. If it is a major one, then you can research the code on Google or come back here for more information.

i hope this helps

Use the correct champion plugs for starters, make sure the wire is firing. If the wire is firing, the coil pack is good. You will need to check compression and fuel delivery after that.
