DTC Parameters

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.

Engine run time is greater than 10 seconds.
Exhaust pipe moisture has evaporated (calculated engine run time between 0 and 200 seconds).
Calculated converter temperature is between 626-1085°F (330-585°C).
Main relay voltage is 10.5-18.0 volts.
No HO2S bank 2 sensor 2 heater control circuit DTCs have been set.

DTC sets if the HO2S bank 2 sensor 2 calculated sensor resistance (based on the actual signal voltage and actual signal current) is greater than 880-8904 ohms (based on exhaust gas temperature); or if an HO2S bank 2 sensor 2 heater control circuit DTC is active for longer than 10 seconds.
