Camshaft Position (CMP) Sensor
The CMP sensor detects camshaft angle at 180-degree intervals (4-cylinder) or 120-degree intervals (6-cylinder) and sends a signal to the PCM. The CMP sensor also detects cylinder No. 1 TDC (4-cylinder) or No. 1 and No. 4 TDC (6-cylinder) and sends a signal to the PCM. The CMP signal is used for fuel synchronization. For CMP sensor location, see CAMSHAFT POSITION SENSOR LOCATIONS table. On MPV, the CMP sensor pulses once per camshaft revolution. On Mazda6 3.0L, 2 CMP sensors are used.
