Tech Feature: Understanding the Differences, Challenges Between Crankshaft Position Sensors
There are two basic types of crankshaft position sensors: Magnetic Field (Variable Reluctance) and Hall Effect. The magnetic type uses a magnet to sense notches in the crankshaft or harmonic balancer. The Hall Effect crank sensor uses notches or shutter blades on the crank, cam gear or balancer to disrupt a magnetic field in the Hall Effect sensor window.
Crankshaft and Camshaft Position Sensor Diagnosis
Nothing is more frustrating than diagnosing an intermittent cranking, no-start complaint with no diagnostic trouble codes (DTCs) and no apparent failure pattern. Much of the time, the cranking, no-start complaint lies with a failing crankshaft or camshaft position sensor. Many of these failures can be heat-related and might require several warm-up cycles to duplicate.
Tech Tip: Saturn Crankshaft Position Relearn/Adaptives Reset Procedure
