If you’ve ever had to jumpstart a car, you know that it can be a frustrating experience. You have to find the battery, get the jumper cables out, and then try to start the car. It’s not always easy or safe to do this. If you have a car with a crank sensor, you might have even more trouble trying to start it.
What Is A Crank Sensor?
A crank sensor is a device that monitors the rotation of the engine’s crankshaft. When the sensor detects a problem with the engine, it sends a signal to the car’s computer that tells it to stop turning the engine. This can cause problems when trying to start the car, as the computer will think there is something wrong with the engine and won’t start it.
How Does A Crank Sensor Work?
A crank sensor is a device that detects when a car’s engine has been turned off by the driver. When the engine is restarted, the sensor sends a signal to the car’s computer, which then starts the engine.
There are two types of crank sensors: direct and indirect. Direct crank sensors work directly with the car’s computer, while indirect crank sensors use a relay to send the signal.
Direct crank sensors are more common because they’re less expensive. Indirect crank sensors can be more reliable, but they’re also more expensive.
Both types of sensors can fail. If the sensor fails, the car won’t start. There are several things that can cause a crank sensor to fail. The most common is wear and tear. Other causes include water damage, corrosion, and electrical issues.
Can A Crank Sensor Cause A Car Not To Start?
Many car owners have experienced a stalled car or a problem starting when they attempt to start their car after applying the crank to the engine. The issue could be due to a faulty crank sensor, which is often located on the car’s crankshaft.
A crank sensor monitors the rotational speed of the engine and sends a signal to the car’s computer. If this sensor becomes faulty, it may cause the car not to start. In some cases, a broken or worn out crank sensor may produce incorrect readings that can lead to a stalled engine.
If you’re experiencing problems starting your car, it’s important to have it checked out by a mechanic. A faulty crank sensor can be corrected by replacing the sensor or by repairing the underlying issue.
How to Fix a Crank Sensor in a Car
If your car won’t start because of a crank sensor problem, there are a few things you can try. Follow these steps to fix the sensor:
1. Clear the crank sensor’s throttle position sensor (TPS) circuit by disconnecting the wire from the sensor and Ground. Turn the key to the “on” position but do not start the engine.
2. Connect the wire from the TPS back to the sensor and turn the key to the “off” position. Start the engine and check for problems with starting or running. If there are no problems, reinstall the TPS.
3. If there are still problems after reinstalling the TPS, replace the crank sensor with a new one.
Conclusion
If you’re having trouble getting your car started, it might be a good idea to check whether or not the crank sensor is working. A crank sensor helps to engage the ignition so your car can start. If it’s not functioning correctly, this could be the cause of your car not starting. You can usually check this by turning on the ignition and trying to turn the wheels (if applicable) – if the crank sensor fails to activate the engine, then it would likely be replaced as part of a scheduled maintenance procedure.
