What does a camshaft actuator sensor do?

What does a camshaft actuator sensor do?

A camshaft position sensor is an electronic device that does what it suggests — monitor the camshaft position and speed — and feeds that data to the vehicle’s engine control module (ECM). The ECM needs this data to control how much fuel enters the combustion chamber and ignition (spark) timing to ignite the fuel.

How does a camshaft actuator work?

The camshaft actuator mounts to the end of the camshaft and either slows or speeds up the opening and closing of the poppet valves via commands sent by the Engine Control Unit. This enables valve timing to be more precise, which helps optimizes engine performance.

What is the function of a camshaft actuator?

Camshaft A camshaft is a shaft attached to the cam. Timing between the rotation of the crankshaft and camshaft is integral to the proper function of a vehicle engine. The camshaft actuator mounts to the end of the camshaft and either slows or speeds up the opening and closing of the poppet valves via commands sent by the Engine Control Unit.

What do actuators do in a car engine?

car engine image by itsallgood from Fotolia.com An actuator refers to a device used to control or move a system or mechanism. A camshaft actuator is used to control camshaft timing.

How does a camshaft position sensor work on a car?

To determine which cylinder is in its power stroke, your car’s computer monitors the rotating position of the camshaft relative to the crankshaft position using a camshaft position (CMP) sensor. It uses this information to adjust the spark timing and the operation of the fuel injectors.

What is the timing between the crankshaft and the camshaft?

Timing between the rotation of the crankshaft and camshaft is integral to the proper function of a vehicle engine. The crankshaft refers to an engine part used to convert reciprocating linear piston motion into rotational motion.
