O2 Sensors readiness fail
 

Hello,

According to DURAMETRIC, I am failing O2 sensor readiness. Luckily I was able to still pass smog last week because of CA law allowing for 1 failure.

Is there anyway to diagnose this down to the exact O2 sensor that's failing?

I'm getting no CEL and subsequently no fault codes.

Any ideas?

Thanks!

Kevin

All the readiness monitors have criteria that has to be met before they run. What's your MY?
