What does the crankshaft position sensor do on a car?
All the modern vehicles have the crankshaft position sensor. It is a component for monitoring the crankshaft’s rotational speed and position. It also sends a report to the engine control unit so that the latter can make the right adjustments should anything is malfunctioning.
How can I tell if my crankshaft sensor is bad?
Another sign of a crankshaft position sensor problem is rough idling. While idling at a red light or otherwise stopped, you may notice the engine grinding or vibrating. When this happens, it means the sensor is not monitoring the crankshaft’s position, leading to vibrations that affect overall engine power.
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.
Why does my Car start when the sensor is gone?
The computer receives a malfunction code when the sensor is completely gone. The symptom starts with difficulty in starting and leaves the car dead one day if you don’t get it fixed. The starting problem could be the result of electrical connection or circuit problems too. 5. Misfiring of the Cylinder

Let’s learn about some crankshaft position sensor failure symptoms so that you can take action when there’s a problem.
Where is the crankshaft position sensor located on a car?
Your vehicle’s crankshaft position sensor is located near the bottom of the engine by the crankshaft. That makes sense because it’s the crankshaft position sensor’s job to measure the crankshaft location. When you’re trying to track down the crankshaft position sensor, look towards the engine’s bottom, generally on one of the sides.
Can a faulty crankshaft sensor prevent a car from starting?

Monitor your engine’s overall function—as well as the speed of crankshaft rotation—by investing in a high-quality, ultra-durable crankshaft position sensor.
What happens when the camshaft position sensor fails?
When the camshaft position sensor fails completely, the engine will not start or will shut off if it fails during operation. If the crankshaft position sensor fails, the engine may not start, or will have excessive vibration if it operates.
How to replace a crankshaft sensor from under the firewall?

Why is my crankshaft sensor not sending correct data?
If the sensor is facing any trouble, it won’t send correct information about the position of the cylinders. It means there will be a gap between the computer receiving data and applying it. For this reason, the accelerator hesitates and does not give a real-time response.
