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: Why Do Camshafts Fail?
The camshaft itself is rarely to blame for cam failure. When the cam core is made at the casting foundry, all the lobes are flame hardened to a depth below the barrel of the core, allowing the cam grinder to finish grind the lobes to an acceptable shape while maintaining the correct hardness.
