What is a crank position sensor?

A crank position sensor, also known as the crank position sensor, is a sensor or component that monitors the position or rotational speed of the crank. Engine management systems use the information transmitted by the sensor to control things such as ignition timing and other important functions. The sensor can also relate other crucial data including the relation of the valves to the pistons and a true sense of engine RPM's.

Where can I find the crank position sensor?

The crank position sensor can be found in the front of the crank on the engine block below or next to the water pump in many applications. It can also be located on the main crank pully or the flywheel. The orientation of each make and model's engine is different, so the position sensor could be near your fender or near your front bumper depending on the car. They are typically made of magnets and oil and work on the principles of the Hall Effect.

What can go wrong with my sensor?

The sensor may become burnt or worn out. The most common causes of crankshaft position sensor failure are exposure to extreme heat when you have a gasket or crank problem, corruption from oil or other engine fluids that leaked onto the sensor, or wear from normal use over a long period of time. When the sensor goes bad, it stops transmitting the signal which contains the vital data for ignition and other parts.

How do I know if I have a bad crank position sensor?

You will know that you have a bad crank position sensor by how your engine idles, how your pistons fire, or how you accelerate. It will usually be more noticeable as you raise the RPM's. With a bad or faulty sensor, you engine may misfire causing motor vibration or backfires. You may also experience hesitation while accelerating or shaking during engine idle. In the worst case scenario, you won't be able to start your car.

Can I change my crank position sensor myself?

You can replace your crankshaft position sensor. The first thing you need to do is figure out how your engine block is placed in the engine compartment. Is it placed in there long ways where the front of the motor is near your bumper, or is it inverted as to where the front of the motor faces your drive or passenger side fender? Once you figure that out, then jack the car up, go near the water pump at the front of the car, and remove components that block access to the sensor. This may include removing parts like the water pump which could be in the way. Once accessible, remove the two bolts holding the sensor into place, remove the wires that send the data, and place in the new part. Replace the other parts as necessary when you are finished. Be sure to test the car to make sure it's working and running smoothly. Before getting started, it's a good idea to consult your owner's manual or speak with a local factory dealership for advice.
