Driving down the road and the old 2006 Aveo engine starts to stumble and buck a bit, and throws a CEL. Scanned and came up with P2297 upstream O2 sensor out of range during deceleration. And P0132 upstream O2 sensor high voltage.
Vacuum lines look okay, but who knows with 272K miles. Wires look good. Heater circuit on the O2 sensor reads about 5 ohms resistance. Which sounds about right from videos. Ratchets and Wrenches video says sensor circuit voltage should read between 0.1 and 0.9 volts. My meter says it's varying between 0.2 and 0.8 volts.
I don't remember if this is the original upstream sensor or not. It could be.
Thoughts?
Thanks.
