Monitored & Set Conditions

Oxygen sensor monitor will run during vehicle shutdown after vehicle has been driven greater than 10 miles with throttle open for at least 3 minutes and battery voltage greater than 11 volts. DTC will set if O2 sensor voltage continues to rise (instead of fall) after the diagnostics has turned the Auto Shutdown (ASD) relay back on. This is a two-trip fault.
