P0031 - 02 sensor test?
Posted: Sat Jul 12, 2014 9:18 pm
Is there a way to test the sensor?
I just replaced the timing belt and water pump, next minute I get this cel p0031 which comes up as the heater control circuit low bank 1 sensor 1 (02 sensor)
I traced the wire and made sure it was connected properly which it was.
Just seems weird that it came on after doing the job....
I think it's 4 wire sensor from memory.
If it matters, the Car is 04 Nb se. All factory.
