Will Crankshaft Sensor Cause Car Not Start

If you’re like most drivers, you’ve experienced the frustrating feeling of being unable to start your car after it’s been parked for a while. You check the battery, the cables, and everything looks okay, but still no luck. The most common culprit is a crank shaft sensor (CKP), which is an important part of your car’s engine. In this article, we’ll explain what a CKP is, how it works, and the possible causes of a malfunction.

What is the Crankshaft Sensor and What Does it Do?

The crankshaft sensor is located on the engine block and monitors the position of the crankshaft. If the sensor detects a problem, it sends a signal to the car’s computer that stops the engine.

How to Reset the Crankshaft Sensor

If your car won’t start, you may need to reset the crankshaft sensor. This is a quick and easy fix that can help solve the problem. Here’s how to do it:

1. Turn off the car and remove the key from the ignition.
2. Remove the intake manifold by removing the three bolts on the front of the engine.
3. Move the crankshaft sensor to one side and disconnect the wire connector.
4. Clean all areas around the sensor with a cloth and let dry.
5. Wire connector back up and replace intake manifold bolts.
6. Start car and check for proper operation of engine sensors.

When to Replace the Crankshaft Sensor

There are a couple of things you can do to troubleshoot why your car won’t start. First, check the battery voltage and charge it if necessary. Next, inspect the crankshaft sensor. If it’s defective, it might not be sending a strong signal to the ECU, preventing the engine from starting. Finally, if all of those steps fail to fix the issue, you might need to replace the crankshaft sensor.

Conclusion

If you’re having trouble starting your car, there’s a good chance that the crankshaft sensor is not working. This device is located on the engine block and helps the computer determine when to start the engine. If it’s not functioning properly, the car won’t be able to start. In most cases, this issue can be fixed by replacing the sensor. If that isn’t an option or if you’re otherwise unable to fix the problem, you may need to bring your car in for repairs.
