P0337 Crankshaft Position Sensor A Circuit Low Input

P0337 Ford OBD-II Trouble CodeDescription:

OBD Trouble Code P0337
Crankshaft Position Sensor “A” Circuit Low
What does the code mean? OBD-ii Code P0337 definition:
The Crankshaft position sensor also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. This information is used by the Powertrain Control Module (PCM) or Electronic Control Module(ECM) to control ignition and fuel injection. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor. When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.
Symptoms Sumptoms of OBD code P0337
– Engine Light ON (or Service Engine Soon Warning Light) – Lack/Loss of Power – Engine Stall
Causes Causes of the OBD-II code P0337
– Harness or connectors (The sensor circuit is open or shorted) – Crankshaft position sensor may be faulty – Signal plate may be damage – Starter motor may be faulty – Starting system circuit – Dead (Weak) battery The Error code is generally activated on detection of the following conditions: – The crankshaft position sensor (POS) signal sent to the ECM is low – The proper pulse signal from the crankshaft position sensor (POS) is not sent to ECM
Solutions – Charge battery – Repair harness or connector – Replaced Crankshaft Position Sensor.
