could use some help on o2 sensors asap/and codes got a diagnostics and is givn me these codes: p0135, p0161, p0420, p0430, p1133.
the 135 and the 161 are o2 sensors, but is there anyway i can tell which ones they are??in front of cat or back of cat b/c i dont wanna have to replace all 4, if 2 are bad...and also i the 420 and 430 codes are catalytic efficiency which i believe are being set off because the 02 sensors?? and i dont know what the 1133 code is...any help will do about the o2 sensors...thanks, and also are all 4 sensors the same ??

If you can. Go in with the scanner and look at the voltage on the sensors. I think they are suposed to be 400 to 600 mv. You could do a search for O2 sensors. I know there are other post with the voltage.

Go to the PCM diagnastics forum on this site and look in the sticky. You can look up your codes from that. For O2 sensors, bank 1 is drivers side of the car always, bank 2 is passenger side. Sensor 1 is the sensor closest to the engine (before the cats). Sensor 2 is after the cats.
