O2 sensor/which one?
I got the code 04 09 which haynes says is "upstream oxygen sensor circuit slow response fault (right bank)". My question is which 02 sensor is this....I have a 98 manual Max. Is it the sensor on the front branch of the y-pipe (the one closest to the front bumper) or is it the one on the back branch, closer to the cat, next to the fire wall?
