Camshaft Position (CMP) Sensor

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