1. Introduction
The crankshaft position sensor is an important component of your vehicle’s engine. It is responsible for detecting the rotation of the crankshaft and sending a signal to the engine control unit (ECU) so that it can adjust the timing of the engine accordingly. Without it, your engine would not run properly or at all. If this sensor fails, then you may experience a variety of symptoms that can range from mild to severe. In this article, we will be discussing the common symptoms of a bad or failing crankshaft position sensor and what you should do if you experience them.
2. What is a Crankshaft Position Sensor?
A crankshaft position sensor (CPS) is an electronic device mounted near the crankshaft in an internal combustion engine. It monitors the rotation of the crankshaft and sends a signal to the ECU to adjust ignition timing and fuel delivery accordingly. This helps ensure that your engine is running at peak performance and efficiency. The CPS typically consists of two parts: a magnetic pickup coil and an electronic circuit board. The magnetic pickup coil detects changes in rotational speed while the circuit board interprets these changes into signals that can be read by the ECU.
3. How Does a Crankshaft Position Sensor Work?
The CPS works by using a magnetized pickup coil to detect changes in rotational speed as well as direction of rotation within the engine’s crankshaft. As this information is sent to the ECU, it adjusts spark timing, fuel delivery, and other parameters accordingly to ensure optimal performance from your vehicle’s engine. Without proper operation from this component, your vehicle may experience poor performance or even not start at all due to incorrect data being sent from this sensor to your ECU.
4. Common Symptoms of a Bad or Failing Crankshaft Position Sensor
There are several common symptoms associated with a bad or failing crankshaft position sensor that you should be aware of in order to identify any potential issues early on before they become more serious problems down the line:
5 Engine Misfire
One of the most common symptoms associated with a bad or failing CPS is engine misfire due to incorrect spark timing caused by faulty data being sent from this component to your ECU which can cause cylinders to fire out of order or not at all resulting in rough running and decreased power output from your vehicle’s engine until it eventually stalls out completely if left unchecked for too long
6 Check Engine Light Comes On
Another symptom associated with a bad CPS is when your check engine light comes on as this could indicate that there is an issue with either data being sent from this component or with its overall functionality itself which should be checked out immediately in order to avoid further damage down the line
7 Rough Idle and Stalling Issues
If your vehicle has been experiencing rough idle and stalling issues then there is also a chance that these could be caused by an issue with either data being sent from this component or its overall functionality itself which could result in incorrect spark timing causing cylinders to fire out of order resulting in rough running until eventually stalling out completely if left unchecked for too long
8 Vehicle Not Starting or Hard Starting
Finally yet importantly another symptom associated with bad CPS is when your vehicle either won’t start at all or starts hard due to incorrect data being sent from this component which can result in incorrect spark timing causing cylinders not firing correctly resulting in difficulty starting up until eventually not starting at all if left unchecked for too long
9 Conclusion

In conclusion, if you have been experiencing any of these symptoms then chances are you may have an issue with either data being sent from your crankshaft position sensor or its overall functionality itself which should be checked out immediately before further damage occurs down the line
Warning Signs: Uncovering the Hidden Dangers of a Failing Crankshaft Position Sensor
What happens when the crank sensor goes bad?
The PCM does not know when to fire the spark plugs and pulse injectors when the CKP sensor fails. As a result the engine may lack fuel and/or spark causing the vehicle to refuse to start.
Will a car run with a bad crank sensor?
If the machine seems to be running normally like before it is more likely to be working. However if the engine starts (you should see the check engine light flashing) it is not possible to run everything without risking damage.
What is the most common problem with crankshaft sensor?
Cylinder misfiring is a common response when your car experiences some crankshaft position sensor symptoms. A failed sensor cannot provide correct information about the position of the piston causing one of the cylinders to malfunction. The spark plug problem got the same response.
What does a bad crankshaft sound like?
Noise from crankshaft bearings can also be caused by low oil pressure damaging the bearing surfaces and ultimately the crankshaft itself. This type of noise is often described as a low rumbling or clicking noise from the engine during acceleration.
Will a bad crankshaft sensor throw a code?
A faulty or failing crankshaft position sensor can cause the check engine light on your dashboard to come on. The diagnostic scan tool will show codes between P0335 and P0338.
What would a faulty camshaft sensor do?
The car does not start: Over time the camshaft position sensor fails which weakens the signal sent to the engine control unit. The car cannot be started when the engine is not receiving the signal. Engine misfire: A failed camshaft position sensor can cause engine misfires.
