The biggest takeaway is this: a crank sensor can pass basic tests and still fail in real-world operation. That’s why I always combine resistance checks, voltage tests, and—most importantly—signal analysis with a scope. If you understand how the sensor works and follow a structured diagnostic approach, you can pinpoint failures quickly and … Read More
