Code P13B2 Description

The P13B2 code indicates a malfunction in the synchronization of the exhaust camshaft sensor. This sensor is responsible for monitoring the position of the exhaust camshaft in relation to the crankshaft, allowing the engine control module (ECM) to adjust timing and fuel delivery accordingly. When this sensor fails to synchronize properly, it can lead to a range of performance issues in the vehicle.
