Details of the p013c OBD Code
P013C code indicates a fault in the O2 sensor slow response in bank 2, sensor 2.
OBD code P013C means that the O2 sensor slow response for rich to lean bank 2 sensor 2. This code is triggered by the Engine Control Module (ECM) when it detects that the downstream oxygen sensor in bank 2 sensor 2 is responding slowly to changes in the airfuel mixture from rich to lean.
This sensor is typically located after the catalytic converter on the side of the engine with cylinder 2. The ECM monitors this sensor to ensure the catalytic converter is functioning properly and to adjust fuel trim as needed for optimal engine performance and emissions.
Mechanic’s Tech Notes
Code P013C indicates a fault with the oxygen sensor slow response in bank 1 sensor 2.
OBDII code P013C indicates a fault with the oxygen sensor slow response rich to lean bank 2 sensor 2. To diagnose, use a voltmeter to test the oxygen sensor’s signal wire for proper voltage changes.
Check the sensor’s wiring harness and connector for any damage, corrosion, or loose connections.
Scan tools can monitor sensor data to confirm proper operation.
If the sensor is faulty, replacing it is usually the fix.
Ensure the new sensor is compatible with the vehicle’s make and model.
