Code P0349 Ford Description

The P0349 Ford diagnostic trouble code (DTC) indicates a problem with the camshaft position sensor 'A' circuit in Bank 2 of the engine. This sensor is responsible for monitoring the position of the camshaft in relation to the crankshaft, which is crucial for the engine control unit (ECU) to determine the correct timing of fuel injection and ignition. An intermittent issue with this circuit can lead to incorrect timing signals being sent to the ECU, causing a range of performance issues.
