Checking CELS and the light is on solid?

[Heli-Mech]

After my alternator shorted out I swapped on a replacement and it is running fine again, this alt only puts out 13.4v. I went for a test drive and had the CEL come on.

-I grounded the CEL wire, and instead of blinking a code it stays on steady??

-I shut the car off, started it back up and no more CEL?

-check for codes again and the light stays on steady?

Strange....

any ideas?

swapped out the ecu for my spare. The ecu is damaged. Must have been a short in the wiring, either in the alternator or the harness i made for the fan. Either way the ecu is cooked, car will run and drive fine on it but not throw or show any codes.

Ian,
Did that ECU arrive yet?

Yeah got it today. Works perfect. Thanks.

Now I don't think the ecu was the problem.
I just drove the car home from work, and it did the same thing. CEL came on after driving out onto the highway. Checked the codes and I am getting a code 55. Not sure what code 55 is, I am looking it up right now.

EGR gas temp sensor from the list of codes I have

Where is the Egr temp sensor located? Was that a California only option?
