O2 Sensor help
At operating temperature.
Volts at idle:
Bank 1 Sensor 1: 0.4 V
Bank 1 Sensor 2: 0.09 V
Bank 2 Sensor 1: 0.73 V
Bank 2 Sensor 2: 0.12 V
Highest Reading:
Bank 1 Sensor 1: 0.9 V
Bank 1 Sensor 2: 1.0 V
Bank 2 Sensor 1: 1.3 V
Bank 2 Sensor 2: 0.9 V
Do these readings seem right?
I've been trying to track down why my DTC monitors for O2 sensor, catalyst, and evap are never ready even after 5000 miles of driving and also a random misfire p0300. I think this may be related?
Should the second sensor always be lower than the first? If so, it looks like there is an issue with bank 1.
