I have a 97 es my check engine light came on a while ago and i had to replace the o2 sensors. My check Engine light is still on though, but it passes admissions is there anyway i can reset it? thanks

 

Have you checked it to see that it brings up the same code as the A/F sensors?

 

no i havent checked since...i just assume nothing is wrong because it passes and if i disconnect my battery it shuts off for like a couple hundred miles than turns back on

 

Massachusetts uses an OBD test for emissions for 96 and up. I live here. How can you pass with a check engine light?!?!!!! Anyways take it somewhere and have the code scanned. It might be a different code like evap or something. If its the same code, you should get original equipment o2 sensors from Toyota. Clearing the code over and over wont fix it. Did you clear it right before you went to get it tested? If so, they just ran a backup tailpipe test, and thats how you passed.

 

go to a advance auto parts store. they should let u use their OBD scanner for free and you can clear the codes so the light will go off.

 

i pass because because before i go get the sticker i disconnect the battery and the cel shuts off. But then it come back on after like 300 miles or so.

 

I have a 2020 IS350 FSport that has a low voltage bank2 code Trying to find out if the wire is light green on a 2020 o2 harness to ecu. I think one of the wires got jacked. Anyone else had the same experience? Thanks
