Crankshaft Sensor: Diagnosis
During cranking the digital signal produced by the sensor is sent to the EMS2000. The EMS2000 expects to receive a signal of 58 targets and two missing targets. If this signal is received the EMS2000 will synchronize itself to the engine. (The EMS2000 knows crankshaft position.) In the event a faulty or improper signal is received the EMS2000 will not begin or allow injection or ignition.
There is no crankshaft back up facility on the EMS2000 because the camshaft sensor target only produces one pulse per revolution.
