What does a bad crank sensor do?

A faulty crank sensor can cause your car to “die” or render it unable to start even though the engine may be operating normally. A crank sensor relays information to the vehicle’s computer, referencing how fast the engine is running, but more importantly the position of the crankshaft and the cylinder.

What does your car do with a bad crank sensor?

Crankshaft sensors go bad all the time. Most modern car engines use a crankshaft sensor to monitor the engines crankshaft rotation. This sensor sends feedback information to the cars computer which then adjusts the ignition and fuel injector timing as engine demands change. When one of these sensors fails it can cause engine misfires, stalling while driving and stalling at idle .
