Automotive Diagnostics Simplified A Beginner's Guide to Crank Sensor Testing

Check the resistance of the crank sensor and see if the resistance is 300-800 ohms. When these sensors fail, they usually stop working altogether. The sensor detects the change of magnet field as the teeth come by. Magnets when heated and shaken lose their mojo and that's why these sensors fail. Unplug the sensor. Check for ground on the black/light blue wire. Turn the key on and check for 5v on the other two wires. Plug the sensor in and backprobe. It is usually mounted on the front or side of the engine assembly and is relatively easy to spot. If you are unsure, check the vehicle's owner's ... The crank sensor, a simple check is just look under the car and see if its still all in on piece. If it is and to check cam sensor you'll have ... The simplest one, take a multimeter and measure their resistance. If you see something close to 2.4 Kohm they are OK most likely. Can anyone tell me how to test the crank sensor? In the GM shop manual you use a scope and check to see if it is putting out 60HZ at 900 rpm ... Connect a 50K resistor from +V to pin 3. Using a multimeter, measure the voltage between pin 2 and 3 while you bring a magnet close to the ... Think it's your crank sensor? Here's a quick test you can do at home to find out! No need for expensive tools. Save money and diagnose it ... How to test crankshaft position sensors without any guess work using multiple methods and tools to obtain and analyze sensor signals.
