Hi! everyone, i'm new at this swap thing and i was wondering if someone tells me or show me where is the CEL on the p28 ecu? i just swap the engine on my crx and now the engine light comes on. i know everybody talks about CEL codes but i don't even know where is located at. So please can someone show me? Thanks

 

CEL=Check engine light.

 

So how do you get the codes on which sensor is faulty?

 

The p28 doesn't have a led on the ecu like obd 0 ecus. There's a wire you need to ground out on the p28. The CEL will blink on your cluster instead of the ecu. I'll post the pin number when i find it. I really don't know which wire cause i'm still obd 0. Hopefully obd 1 this weekend.

 

i grounded the check engine light wire and the CEL is blinking.

 

search check engine light and learn how to read what those blinks mean.
