Check Engine Light Question.....

[PlatinumTracks]

I'm just curious.....

Does it mean anything if there is a delay before the check engine light cuts on...? were talking like 10-20 sec

The ECU Coolant Temp is the reason for it comming on...

Special Thanks To:

J Dub and AJ for their help......
Nice to see that there are people who care about us N/A owners

the knock sensor was just grounded bad...

If anyone has an ECU coolant sensor for sell PM me.....

Do you mean the CEL comes on when you start the car and stays on? I'd check for codes if so.

If it comes on and stays on then you have a code. The delay dosen't mean anything I don't believe.

That's not unexpected for an ECU temp sensor. It takes a bit for the ECU to detect improper voltage. There's a test in the TSRM EFI section for that sensor...I'd give it shot before I spent $$$ on another one. (could be your wiring)
