B1S2 02 Sensor Fuel Trim is Reading 99.06
Time for a Smog check and I barely passed 2 years ago, so I hooked up Autoenginuity to check out the sensors. All sensors are in the good range except B1S2 02 Sensor Fuel Trim it's reading 99.06 pegged on max.
I'm getting no CEL, so I'm wondering if this is a problem?

Not sure there's a question there Carguy? B1S2 the sensor downstreem of Cat. is reading 99.06 in the red. Do you know the Denso part # for B1S2?
Anyway I barely passed smog.
Max allowable hydrocarbons is 50 ppm I had 47ppm. see below.
Also see the Autoenginuity chart. showing B1S2 O2 Sensor which is the red line.

I didn't know that CA was still using the sniff test on newer cars. In OH they just plug in to the port, no CEL and you pass.

So does the CEL light up in the self test mode? ... The first time you move the ignition key to on/run position ... instrument cluster warning lights should turn on ... telling the driver all warning bulbs are working. ... I pause and and confirm while I put my seat belt on.

Found everything about B1S2 oxygen sensor at

Thanks Carguy!
Think I'll just replace even though it doesn't do anything except tell the ECU oxygen levels?
CEL light works. Goes out when car is started.
