Chevrolet Equinox Crank Position Sensor
About Crank Position Sensor
This is the main sensor in the engine management system without which the engine will not operate. The crank position sensor also called the crank angle sensor or motor speed sensor measures the crankshaft position and the spinning speed of the crankshaft. This sensor sends the information calculated into the ECU which determines the time of ignition and fuel injection, together with the data from other sensors.
What is the Purpose of Crank Position Sensor?
The sensor for the direction of the crank defines the position of the crank in angle and the velocity of the engine in rpm. These two are very important parameters for engine management to control systems such as timing of ignition and timing of fuel injection that directly affect the power output of the vehicle.
How Crank Position Sensor Works?
The CPS, if magnetism operates on the rules. Most of the current sensors are called sensors for the hall effect. This generates energy from magnetic field penetration. A toothed wheel creates disruptions in the magnetic field resulting in a continuous and uniform on and off pattern that is translated by the ECU to the speed of the crankshaft. Only the older sensors operate on the same principle but differently slightly. The changes in the magnetic field induced on the crankshaft by the metal pins produce voltage that is converted by the ECU into the engine rotational speed.
Where is Crank Position Sensor Located?
The CPS location is subjective to the manufacturer of the vehicles. The CPS is most usually mounted on the cover of the timing belt.
