Your car has a variety of sensors on board that regulate other parts of your car and keeps your performance in check. Without properly working sensors in places like your engine, your car can become increasingly unreliable in more ways than one, and you run the chance of being stranded with a broken-down car. Many of these sensors are extremely important, and the crankshaft position sensor is one of those.

Today, we are discuss why the crankshaft sensor is so important to your vehicle, what the symptoms of a bad crankshaft sensor look like, and what to do if you suspect it to be to blame for your recent engine problems.

What Is A Crankshaft Position Sensor?

A crankshaft position sensor is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. 

This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters. Before electronic crank sensors were available, the distributor would have to be manually adjusted to a timing mark on petrol engines.

The crank sensor can be used in combination with a similar camshaft position sensor to monitor the relationship between the pistons and valves in the engine, which is particularly important in engines with variable valve timing.

This method is also used to “synchronise” a four stroke engine upon starting, allowing the management system to know when to inject the fuel. It is also commonly used as the primary source for the measurement of engine speed in revolutions per minute.

FAQs

1.What happens when a crankshaft sensor goes bad?

The sensor's role in managing ignition timing and fuel injection is crucial, and when these processes are disrupted, it can lead to inefficient combustion and stress on various engine parts. Poor performance. A car with a bad sensor might experience rough idling, prolonged cranking, or may not start at all.

2.Can you drive a car with a bad crankshaft sensor?

Some common symptoms of a bad crankshaft position sensor are an illuminated check engine light, hard starting, and misfires. A bad crankshaft position sensor can prevent your vehicle from starting and leave you stranded somewhere, so it's best not to drive until you fix this part.

3.How do I know if my crankshaft is bad?

You will know that it has become faulty when you experience symptoms of a bad crankshaft bearing that include knocking noises coming from the engine, metal shavings in the oil, low oil pressure, and crankshaft bearing noises.

4.Can a car start without a crank sensor?

The Crankshaft Position Sensor (CKP) is used by the computer to determine where the crankshaft is on the #1 cylinders' cycle in order to determine when to time the spark and fuel injection. Without it, the engine will not start because there will be no ignition and in many instances, no fuel injection either.

5.Will disconnecting battery reset crankshaft sensor?

Disconnecting the car battery from your vehicle does not reset your crankshaft position sensor (although this can still depend on the vehicle). Your engine control module will reset all of its code, but this is not the same as resetting and relearning a crankshaft sensor.
