I need to have my car smog checked ASAP and my check engine light is on. Does anyone know how to temporarily disconnect it so I can pass my smog check. (Car should pass emissions but CA will not pass you if the light is on) The O2 sensor is new and there are no exhaust leaks. Thanks for the help. I have already done a few searches for this info but could not find info on how to disconnect.

Thanks

 

pull the gauges out and disconnect it from the back.

chances are though that if the check engine light is on, you won't pass emissions.

also try unplugging your battery for a while to reset the ECU.

 

THanks Matt....guess I'll have to spend some money checking the code
code before I get a smog check. According to the my Nissan dealer it it is my ECU but since I don't trust them I need a second opinion before drop hundreds on a new ECU. DAMN!!
