Code P2414 Description

The P2414 code indicates an O2 sensor exhaust sample error for Bank 1 Sensor 1. This means that there is a problem with the oxygen sensor located in the exhaust system before the catalytic converter on the side of the engine with cylinder 1. The oxygen sensor is responsible for monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module to adjust the air-fuel mixture for optimal performance and emissions.
