Question about 2001 Oldsmobile Alero
Light has been on for about 2 years, Replaced both O2 sensors twice. Catalitic converter and Muffler twice. Most of the driving is highway driving. if prolonged city driving the light will go out for a while, how ever it appears that the gas milage goes down. I am at looking for solutions. my mechanic says that every thing checks out while idling in the shop and the codes indicate it is the O2 sensor or the catalitic converter. It appears that he want to keep replacing parts until we get the right one
Code P0132 is O2 sensor voltage high bank1 sensor 1, P0137 is O2 sensor voltage low bank 1 sensor 2, P1189 indicates a fuel control problem bank 1. It could be either the O2 sensors or a convertor. Could also be intake manifold gaskets. GM had a lot of problems with the lower intake gaskets leaking on the 3.1 and 3.4 engines that was linked to their Dexcool coolant. In fact they just lost a class action lawsuit about it. check with the dealer and see if the intake problem has been taken care of. Hope this helps.
