The P1380 code for Mazda vehicles indicates a specific problem related to the camshaft position actuator circuit, bank 1. This component plays a crucial role in engine operation by controlling camshaft timing. Camshaft timing manages the opening and closing of the valves, which directly impacts engine performance and efficiency. When a problem is detected, the engine control module (ECM) records this error code.
OBDII Code P1380 Mazda: Causes and Symptoms
Common Causes
Here are the main possible causes of the P1380 code:
