Is there a way to check to see if my p28 is damaged or not without trying another p28? I have a solid cel and have ruled out everything but the computer. Any help is greatly appreaciated...

 

try opening the cover up and see if anything is burnt....

 

I did that and everything looks good.

 

is the ECU chipped? (common problem, remove J1 or try a different chip)

by solid CEL you mean even with the service connector jumpered right? (just checking)

Yes the ECU is chipped and I tried removing J1 but the CEL is still constant. My car is a CRX with a d16z6 motor using a obd obd1 conversion harness which comes with a wire to jump with a ground source in which to check for codes. I tried jumping these wires to try and check for codes but the CEL remains constant.

 

If you can just check your p28 on someone elses car or try another ecu on your car..
