What is the operation of the exhaust Camshaft Position (CMP) sensor?

The Camshaft Position (CMP) sensor of the exhaust is similar to that of the Crankshaft Position sensor because it also generates signal pulses four times in every revolution in a four-cylinder engine or five times in a five-cylinder engine. Additionally, there is an intake CMP sensor for the five cylinders engines which produces one pulse per camshaft revolution. LH9 V8 engines with VVT (variable valve timing) do not require CMP sensors. On LH8 engine, it is located at the front of the timing chain cover and some models will require removal of the water pump to replace this sensor. To take out the sensor, remove its electrical connector from it which is found at the front right corner of inline engines' cylinder head. There are some components on these engines that are exclusive to only a few models that have a 5-cylinder engine-such as mechanical throttle body, integrated EGR and CMP Sensor for Intake Cam, etc. The camshaft position sensor can be removed by unscrewing its retaining bolt and pulling it away from the head. The installation process is simply the reverse of removing it. However, make sure to fit a new O-ring into the fitting hole prior to installing it. Lastly, lubricate this O-ring using diesel fuel or motor oil before assembly.

Chevrolet Colorado Camshaft Position Sensor

Chevrolet Colorado Cars use Camshaft Position Sensor as an important element that helps to check the position and speed of a camshaft which is transmitted to the engine control module in order to control fuel injectors and ignition time. Located above the camshaft it is sometimes mobile for different automobile models. Besides the Crank Sensor, the Camshaft Position Sensor plays a critical role in the correct coordination of certain engine components for operation and efficiency, and thus the relevance of the model to the engine. Malfunctioning of a sensor causes undesirable characteristics in the operation of an engine; hence, it must be maintained and checked frequently.

Each OEM Chevrolet Colorado Camshaft Position Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
