Description
Engine Camshaft Position Sensor
Introdution
- On many engines with distributorless ignition systems and sequential fuel injection, a camshaft position sensor is used to keep the engines control module informed about the position of the camshaft relative to the crankshaft.
HOW DOES CAMSHAFT POSITION SENSORS WORK?
- By monitoring cam position (which allows the control module to determine when the intake and exhaust valves are opening and closing), the control module can use the cam position sensors input along with that from the crankshaft position sensor to determine which cylinder in the engines firing sequence is approaching top dead center.
- This information is then used by the engine control module to synchronize the pulsing of sequential fuel injectors so they match the firing order of the engine. On some applications, input from the camshaft position sensor is also required for ignition timing.
- The camshaft position sensor may be magnetic or Hall effect, and mounted on the timing cover over the camshaft gear, on the end of the cylinder head in an overhead cam application, or in a special housing that replaces the distributor (in the case of some of the GM applications). Operation and diagnosis is essentially the same as that for a crankshaft position sensor.
