If your car won’t start because of a bad crank sensor, don’t panic. There are a few things you can do to try and fix the problem before calling a tow truck. In this article, we will explain what a crank sensor is, what causes it to go bad, and some common fixes.
What is a crank sensor?
A crank sensor is a device that monitors the rotation of the crankshaft in an engine. The sensor tells the engine control system how many turns the crankshaft has completed and whether it is rotating correctly. A bad crank sensor can cause the engine to stop working or to run erratically.
How does a crank sensor work?
A crank sensor is atype of sensor in a car that detects the engine’s revolutions per minute (RPM). It sends this information to the vehicle’s computer, which can then determine how much fuel to inject into the engine for optimal performance. A crank sensor can fail for a variety of reasons, including dirt or debris getting lodged in its mechanism. If this happens, the sensor won’t be able to accurately measure RPM and will result in poor fuel economy and performance. If you experience problems with your car’s crank sensor, be sure to take it to a mechanic for inspection.
What are the symptoms of a bad crank sensor?
A bad crank sensor is typically the first indication that something is wrong with your car, and can often lead to other issues down the line. If you experience any of the following symptoms, it’s time to take your car in for a checkup:
Your engine won’t start
Your car lags or stalls when you try to accelerate
Your car has low horsepower or torque
If you notice any of these problems, it’s best to take your car in for a checkup as soon as possible. A crank sensor can often be replaced relatively cheaply, so it’s worth taking the necessary steps to avoiding future headaches.

Conclusion
Unfortunately, many car owners experience trouble with their car’s crank sensor. This is a device that monitors the engine’s rotation and sends signals to your car’s computer to help it run smoothly. If your crank sensor detects any problems, like when the crankshaft isn’t turning properly, the engine will be prevented from starting. In most cases, this can be remedied by replacing the crank sensor. However, if the problem is more serious or if it has been present for an extended period of time, you may need to have the entire engine replaced.
