How does the crank sensor work in an engine?
Now our engines are computer controlled, with one of the main inputs being the crankshaft position sensor. Just about every engine today has a crank sensor that sends a signal to the computer regarding engine speed. This signal allows the computer to calculate timing and to identify various issues with the engine.
What are the symptoms of a bad crank sensor?
Knowing the symptoms of a failing crank sensor will help to diagnose many running issues. When a crank sensor is in the early stages of failure the vehicle’s computer may turn on the “Check Engine” light. You may not have any other symptoms, but this is the vehicle’s way of telling you that it sees something that is not right.
What is an inductive crankshaft position sensor used for?
The specific problem is: This article needs editing by an automotive engineer. (January 2016) Typical inductive crankshaft position sensor. A crank 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.
Why is the position of the crankshaft so important?
The speed and position of the crankshaft are two key parameters that the car’s computer uses for engine management calculations. So, you may understand how important it is for the sensor to work without any glitch. Let’s learn about some crankshaft position sensor failure symptoms so that you can take action when there’s a problem.
What does a bad crank sensor do?
A faulty crank sensor can cause your car to “die” or render it unable to start even though the engine may be operating normally. A crank sensor relays information to the vehicle’s computer, referencing how fast the engine is running, but more importantly the position of the crankshaft and the cylinder.
What is a bad crank sensor?
A bad crank position sensor can worsen the way the engine idles, or the acceleration behaviour. If the engine is revved up with a bad or faulty sensor, it may cause misfiring, motor vibration or backfires. Acceleration might be hesitant, and abnormal shaking during engine idle might occur.
What problems do crank sensors causes?
Top 5 Bad Crankshaft Position Sensor Symptoms Irregular Stalling. The crankshaft position sensor is comprised of numerous wires which run to the engine control module and crankshaft. Difficult Starting Vehicle. When you have a faulty or damaged crankshaft position sensor, one of the first things you’ll notice is that your vehicle will be difficult to start. Engine Vibration.
Where is the crank sensor located?
The crank sensor is either located on the main crank pulley, the flywheel, the camshaft or on the crankshaft itself. The most common location is at the bottom of the engine block, where the crankshaft is. The crank sensor is one of the most important sensors in a car, if not the most important.
