Rooster2 Posted March 26, 2013 Share Posted March 26, 2013 My 98 OBW with 95 2.2 motor threw a CEL. I had the code read at an automotive store. Guy who read the code, said reader says bad O2 sensor, "bank 1, sensor 2." I am guessing that is the first O2 sensor coming off the motor. Can anyone confirm this?? Thanks.............Rooster2 Link to comment Share on other sites More sharing options...
ShawnW Posted March 26, 2013 Share Posted March 26, 2013 This sort of diagnostic isn't often accurate with just a code read. Bank 1 on your car is irrelevant since you just have a front and rear sensor. Sensor 2 means rear 02 sensor. Which code number did he give? Bank 1 on a Subaru is the passenger side bank.

Never got a code number, just the announcement, bank 2, sensor 2. I should have asked for the code number. It has always been my experience that the first sensor closest to the motor is the one that goes bad. I have never had the sensor further back in the exhaust system go bad. Prolly better if I go elsewhere to get a 2nd reading, and get the code number this time. 2 Link to comment Share on other sites More sharing options...
