P0345 meaning: Camshaft Position Sensor A (Bank 2) Explained
Understand P0345 meaning, causes, and fix steps. Learn DIY checks, when to consult a specialist, and common fixes for camshaft sensor issues.
P0345 meaning is a diagnostic trouble code indicating a problem with the camshaft position sensor A circuit on bank 2. This sensor monitors camshaft position to help control ignition timing and fuel injection. When the engine control module (ECM) detects a signal that is too slow, too fast, or out of expected range, it triggers the P0345 code. This issue can affect engine performance and emissions, so it should not be ignored.
