P013A OBD-II: O2 Sensor Slow Response - Rich to Lean

P013A Severity

Moderate

Will P013A go away on its own?

Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.

For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.

Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.

What causes OBD-II fault code P013A?

The purpose of the oxygen sensor is to measure the oxygen content in the exhaust gases after they leave the combustion process of the engine. The engine control module (PCM) is constantly adjusting the amount of fuel delivered to the engine based off of the oxygen sensor's signal. If the PCM does not see the Oxygen sensor reading constantly changing with the fuel adjustment, it will set code P013A.
