P015C — O2 Sensor Delayed Response - Rich to Lean Bank 2 Sensor 1

Puedes seguir conduciendo con precaución

Descripción

This code means that the oxygen sensor on Bank 2 (the side of the engine with cylinder #2) is taking too long to switch from reporting a rich fuel mixture to a lean one. This indicates a problem with how the sensor is reading the exhaust gases.
