Unleashing Engine Performance The Ultimate Guide to Testing Crank Sensors

A glowing check engine light, stalling, poor acceleration and bad fuel mileage are all possible signs your camshaft position sensor may be failing. 1. Locate the crankshaft position (CKP) sensor harness connector. It's the right, black connector on the firewall (group of 5 connectors), left side of block. There is no test procedure in the diesel part of the manual, but there is for the gas. This is where the resistance reading from pin 2 to 3 comes from. From ... The PCM uses the signal from the crankshaft position sensor to determine at what time to produce the spark and in which cylinder. The signal ... A mechanic will first need to perform a visual inspection of the sensor and its wiring to check for any obvious signs of damage or corrosion. They will then use ... Best way to check if the CSP sensor is the culprit....and for free. Go buy a new one and put it in. Crank it up and go for a drive. If it works keep it. 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 ... Use an analog meter set on the lowest setting. When the metal tab passes by the sensor, it generates a small voltage spike. You can test this by ... 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. If you've got a multimeter, you should be able to test for the required resistance, as well as checking voltage as you try turning the engine over.
