The crankshaft sensor is used to set the ignition timing, supply the rpm signal to the ECU, and determine the engine's speed. Both of these sensors will need to be replaced if they are faulty. Symptoms of a bad crankshaft sensor include engine backfiring or stalling, engine vibration, and ignition malfunction. Of all the symptoms that stem from a blown head gasket, few are as dangerous as the mixing of fluids that are not supposed to come into contact — namely coolant and oil. When the coolant seeps into the oil, the oil’s properties can become corrupted to the point where the engine is robbed of its lubrication.
