Changed O2 Sensor, need to reset ECU???

Hey guys...

I'm having issues passing my emissions test in Phoenix, so I took it in to get diagnosed and they tell me the O2 sensor is bad... ok, that happens, so I go out and but the Bosch universal for $20 instead of paying them the $197 and labor to do it, and I buy plugs cause he says they need replacing.

I change out the O2 sensor and plugs on Sunday afternoon, take the care for a drive and it runs great! Better than before? If it does, I can't tell. I ran great when I got it and it runs great now.

So, the question is, do I need to reset the ECU for it to take the new O2 sensor or not? If so, how do I do it? Thanks for all the help!!!

I figured about the ECU, but I thought if I did, someone could post it here really quickly.

Thanks for the response. I think I'll take the car back to emissions testing early next week and see if it passes.

Lots of info has been posted on emissions and you will just learn more by using 'search'. Suggested that you have new plugs and make sure the cats are hot. I had no problems in Oregon with my stock 29k FD.

BTW, Reset the ECU by disconecting the neg battery terminal and hold the brake for 30 seconds....

Thanks. I've been searching since I posted, just using the wrong key words. Funny how that works.

Thanks for the ECU procedure!!!

by the way, to get the OEM O2 sensor without taking it in the shorts...goto www.oxygensensors.com
Around $60-70 gets you the OEM sensor with factory plug-total plug-n-play. No need to splice a universal sensor again!

Thanks for that website. There was no way I was paying $197 for an OEM and then paying the tech 2 hours labor to change it out.
