What causes a crank angle sensor to fail?
Faulty Wiring Harness The wiring harness is the most common problem associated with crank sensor failure. This can be the result of improper voltage, ground or return circuit problems. Loose wiring, oil and debris can wear down the wiring harness, causing a disruption of voltage or wear and tear on the wiring itself.

How does the crank sensor work on a car?
How the crank sensor branches off the troubleshooting tree varies from model to model. On most cars, it’ll affect both spark and injector firing, but on others, the ECU must see the crank signal in order for the fuel pump to run at all.
