2017-10-10

Description:

  • The fault code P0337 indicates that the circuit for the crankshaft position sensor A is not receiving enough voltage, leading to a low input signal. This may cause issues with engine performance or starting.

Possible Symptoms:

  • Engine may not start or may run poorly

  • Illuminated check engine light

  • Rough idle or stalling

  • Reduced engine power or acceleration

  • Poor fuel economy

Possible Causes:

  • Faulty crankshaft position sensor

  • Damaged, loose, or corroded wiring or connections in the circuit

  • Failed powertrain control module (PCM)

  • Low battery voltage

Related Parts:

  • Crankshaft Position Sensor: The crankshaft position sensor monitors the position of the crankshaft to regulate fuel injection. Problems lead to engine misfire and engine stalling

Possible Solutions:

  • Replace the crankshaft position sensor

  • Inspect and repair any damaged wiring or connections in the circuit

  • Clean and secure any loose or corroded connections

  • Check battery voltage and replace if necessary

  • Replace the powertrain control module (PCM) if needed
