While the crankshaft position sensor is a pretty sophisticated piece of equipment, and you might be intimidated by the idea of replacing it yourself, you probably shouldn’t be. With a good set of instructions, the right tools, and some effort, you can replace your crankshaft sensor yourself.
How can I tell if a crankshaft sensor is gone?

- Your Check Engine Light is Blinking.
- It’s Difficult to Get Your Vehicle to Start.
- Your Vehicle is Stalling and/or Backfiring.
- The Engine is Making Your Vehicle Vibrate.
How much does it cost to replace a crank sensor?
The average cost for a Crankshaft Position Sensor Replacement is between $178 and $226 but can vary from car to car.
What is a bad crank sensor?
Function. A bad crank position sensor can worsen the way the engine idles, or the acceleration behaviour. If the engine is revved up with a bad or faulty sensor, it may cause misfiring, motor vibration or backfires. Acceleration might be hesitant, and abnormal shaking during engine idle might occur.
What can make crank position sensor go bad?
The crank sensor may have been struck by the timing belt when it snapped. This can cause damage to the wiring harness and the sensor. Even though you may have had the belt replaced, the sensor can still be damaged and your vehicle may crank but fail to stay started after a few minutes.
What are the symptoms of a bad crankshaft position sensor?

How to test crank sensor?
Another way to test the crankshaft sensor with a multimeter is by checking the output voltage with the engine cranking. You will need an assistant to do this. Be very careful around moving parts as you do this. Probe the wiring connectors and measure the output voltage in AC millivolts.
