Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Exhaust Camshaft Position Sensor
FUNCTIONS WITHIN THE SYSTEM
Exhaust camshaft position sensor detects the protrusion of signal plate installed to the exhaust camshaft rear end.
INDIVIDUAL FUNCTION WITHIN THE SYSTEM
The ECM inputs the voltage change caused by the change in magnetic field generated close to the exhaust camshaft position sensor, and the timing of the change, as signal voltage.
INDIVIDUAL OPERATION
The exhaust camshaft position sensor consists of a permanent magnet and Hall IC. When engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. Due to the changing magnetic field, the voltage from the sensor changes.
Component Location
The exhaust camshaft position sensor is installed on the engine rear side.
