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.
Camshaft Sensor: Notes
The signal from the camshaft sensor enables the EMS2000 to detect the position of the camshaft in relation to the position of the crankshaft. This allows the EMS2000 to synchronize the fuel injection and ignition spark.
The camshaft sensor is located in the front of the engine cylinder head just below the valve cover. The sensor reluctor ring is bolted to the front of the camshaft.
A digital signal is provided by the sensor in the range of 0-5 volts. The Hall Effect device produces one pulse for each revolution of the camshaft. The reluctor is of a half moon form with a single "tooth" that extends over 180° of the camshaft rotation.
