Oxygen Sensor

17522 - Oxygen (Lambda) Sensor: B1 S2: Internal Resistance too High
P1114 - 008 - Implausible Signal - Intermittent
Readiness: 0000 0000


Is the oxygen sensor bad?

Check the 02 sensor resistance. Brown connection is Pre cat sensor (B1S1) and the black is the post cat sensor (B1S2). They are on the drivers side firewall. Take a look at this DIY.

Thanks for the info. That will tell me if the 02 Sensor is bad?

I did it this afternoon and no reading from both O2 sensors.
