The pale orange engine light on the dashboard came on in my 2004 PT/Cruiser. I heard such things that even the catalytic converter may do this. What else could be the problem?

Check oil again and all fluids. Take top where oil fill is and when engine I'd running should feel pressure and or little oil slashes.

Change your dashboard light switch/dimmer. It either has a bad connection, or is faulty altogether.

Some of the possible causes for the P0420 check engine light to become lit include the oxygen (O2) sensor not working correctly, a damaged or leaking exhuast (pipe, manifold, catalytic converter) or a damaged catalytic converter. ----------------------------------------------------------------------------------

Have battery load tested, and alternated tested. Check. Battery cable connections, make sure they are clean and tight.

get code check and it sounds like fuel filter

There is but one source for the catlytic converter for your car, that is your local dealers parts dept. Aftermarket cats will not work, they will cause the check engine light to come and set code P0420.

it could be many things..... i would take it to auto zone parts store and have them hook it up to the computer..... then it will tell you what the problem is....

HEY EVERYONE.... SORRY FOR THE CAPS BUT I FINALLY FOUND SOMEONE WITH A BRAIN AND GOT THIS PROBLEM FIXED FOR FREE!!!!!!!! Now I have about 20 forums to go back to and save hundreds of PT Cruiser Owners the time money and aggrevation we have all experienced.
I have to give my friend John (now in my opinion the best auto mechanic in South Florida) the credit. Took him 10 minutes to give me the answer, took several Chrysler dealerships about 5 visits and weeks of diagnostics to finnaly agree with him!
