I just failed a smog test today.

Theres 3 fails.

RESULT ECS
FAIL- MIL

HC (PPM) 15MPH
MAX: 60
AVE: 9
MEAS: 72

THIS VEHICLE FAILED THE MIL/CHECK ENGINE LIGHT DUE TO OBD COMMUNICATION FAILURE.


I just bought the car and was told it passed smog. I can see that it wasn't too bad of a fail. The swap passed BAR w/sticker and the smog tech's visual.

The ECU is a P75 which I think is from an LS with a jumper harness.
I think this link is what the harness looks like https://www.jhpusa.com/store/pc/view...idproduct=2040

But heres a picture of the actual harness and ECU.

The ECU is probably converted for VTEC.


I only drove about 2 miles to the smog station from the first start up of the day. Could this be the reason behind the HC (PPM)?

I plan to buy a GSR OBD2 ECU tomorrow to replace the LS ECU. Will I be able to hook up a the GSR ECU to my original pins without the harness?

Can the the failure to communicate with the OBD by caused by the LS ECU being converted/OBD1?

NO CELs. The light turns on and off like every other bulb.
