It worked! I changed the O2 sensor on my truck last night, and it's very
happy now. When I first changed it, the PCM was still running the engine
very rich, so I pulled the battery cable to erase the memory (clue was
that the FSM said that code 51 is O2 sensor out of range or "Additive
Adaptive Memory at rich limit"). This morning the PCM had lost all bad
codes, and evidently started from the default mixture. No rotten eggs!
I hope my gas mileage picks up too.
BTW. NAPA stocked the Bosch sensor, which comes with leads that are about
two inches shorter than stock. I spliced on most of the stock harness, so
the connector is actually accessible now (lead goes up and over the tranny).
Stock sensor had 89K miles. Appears the sensor heater was open.
Happy Motoring!
Jim
