Mine has been giving 138 and 139 codes, bank 1 sensor 2 O2 sensor,,runs fine still though.
Its a Cal Emissions model, lucky me, and has 4 o2 sensors. i am having trouble finding out which sensor is bank 1 Sensor 2.
Anybody know which of the 4 connectors this one is?
Nirav, you care to take this one?
obviously this person did not search the newsgroup first
Sure. There is a TSB to update the ECU software for your vehicle. Add to the that the chance that the problem may be covered under the
7yr/80k emissions warranty, it might be worthwhile to call your local dealer and see what they can do for you. You might be pleasantly surprised....Nirav
