O2 sensor question, PCM section useless, sorry. I just need to know which sensor Bank 1 sensor 2 is, that's all for now. My SES light is on but I can't get a response in the other area of this site. Code is po138 if you were wondering.
Bank 1 is driver side (1,3,5,7 pistons), bank 1 is called bank 1 because it's on the #1 piston side of the engine. Number 2 sensor is the sensor after the catalytic converter, rear 02 sensor. Sensor 1 is before the converter, sensor 2 is after the converter.
