The crank sensor


We will explain the function of the crank sensor, why it needs to be replaced if damaged, and the most obvious symptoms of its failure because it is one of the crucial components of the car.

What is the crankshaft?

Before discussing the crank sensor, it is important to understand what the crankshaft is or what is meant by the term. The crankshaft is a crucial component of a car engine that connects to the machine's pistons via connecting rods (pillars) and translates the pistons' motion into rotation.

What is the function of the crank sensor?

The function of the crank sensor comes from its name, which refers to the crank shaft. The engine's revolutions per minute, or the number of revolutions recorded by the crank sensor, are calculated and shown on the car's counter as RPM. As with the other sensors in the car, the crank sensor's job is to transmit information to the computer of the vehicle.

The function of the crank sensor is the same regardless of the car's brand, form, or kind (operating by magnetic induction or the Hall effect, etc.). Failure of the crank sensor symptoms

 The most obvious symptoms of crank sensor degradation include

Be careful when changing the crank sensor

When removing a faulty crank sensor from its plug and replacing it with a healthy one, care must be taken of the temperature of the vehicle and ensure it is cold. The battery must also be disconnected and then reconnected.

How to repair crank sensor

The crank sensor regulates the timing of the ignition system and other crucial engine operations in internal combustion engines, but what happens if it breaks from repeated use? Here are the crucial measures to assist you in fixing it:

Disconnect the ground cable from the battery after raising the car with the ground jack so you can get underneath it. Don't forget to support the car with jacks. Disconnect the cables that link the starter's battery to it. In order to prevent short circuits when reconnecting the wires, it is crucial to mark them. Using an appropriate socket, remove the nuts or bolts holding the starter motor. To access the damaged crank sensor, remove the starter. Once the starter is gone, the crank sensor should be visible on top of the engine.

To disconnect the connector from the sensor, which is secured with one screw and may be removed using the right socket, first loosen the link in the center of the crank sensor using a screwdriver. The crank sensor can be removed by positioning the door panel remover on its side, separating the sensor from the engine block, and wriggling it out of the way. Check to see if it has any flaws or faults, and if you find that it is damaged, replace it with a new one.

How do you clean the crank sensor?

Utilizing the wrench, cut the negative battery cable. Consult the owner's manual to find where the crank sensor is located in your car. Save the locations of the three wires that are linked to the crank sensor so you may reconnect them later. Apply a tiny bit of solvent by spraying it onto the crank sensor. With a cloth, dry-clean the sensor. Tighten the bolts after replacing the camshaft sensor. The negative battery cable should then be connected after the three wires have been connected where they belong.
