Generic · emissions
Data confidence85%
The control module detected a fault associated with the O2 Sensor Delayed Response - Rich to Lean Bank 1 Sensor 2 circuit or function; the stored code identifies the affected component rather than a single failure mode.
Symptoms
MIL illuminated
Possible increased fuel consumption
Possible unstable idle
Possible causes
Aged or contaminated oxygen sensor
Sensor heater circuit fault
Wiring or connector fault
Exhaust leak near the sensor
Mixture fault upstream of the sensor
Recommended checks
Read live sensor voltage/current and heater status
Inspect wiring and connectors
Check for exhaust leaks near the sensor
Check fuel trim values for upstream mixture faults
Powertrain: engine, transmission and driveline systems.
