WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Mazda Tribute, 2002 Mazda Protege5, 2002 Mazda Protege, 2002 Mazda Millenia, and 2002 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.
The Camshaft Position (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.
