Diagnostic Aids

WARNING: This page is about a different car, the 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

If an HO2S bank 1 sensor 2 heater control circuit DTC is also set, diagnose that DTC first. A heater control circuit DTC that is active for a certain length of time will set this DTC. Then, if P0140 is also set, diagnose that DTC next. An open in the sensor signal or sensor return may set DTC P0141.

Heater element resistance should be 7.0-20.2 ohms.
