OBD II Fault Code

  • OBD II P0341

Fault Code Definition

  • Camshaft Position Sensor "A" Circuit Range/Performance

What does this mean?

The Camshaft Position Sensor measures the exact rotational position of the camshaft. This provides a critical data signal used by the Powertrain Control Module (PCM) to control Ignition Spark and Fuel Injector Timing. When this signal is either out of its specified range or interrupted for any reason, code P0341 is set and the MIL or Check Engine Light is illuminated. 

Symptoms

  • Check Engine Light will illuminate
  • Hard starting/cranking without starting
  • Engine hesitation or stalling
  • Engine dies and will not re-start
  • In many cases, no abnormal symptoms may be noticed

Common Problems That Trigger the P0341 Code

  • Defective Camshaft Position Sensor
  • Faulty or corroded Camshaft Position Sensor wiring or connections
  • Defective Crankshaft Position Sensor
  • Rough running/misfiring Engine

Common Misdiagnoses

  • Camshaft Position Sensor is replaced when the cause is a defective Crankshaft Position Sensor 
  • Camshaft Position Sensor is replaced when the cause is a poor connection or chafed wiring
  • Camshaft Position Sensor is replaced when the cause is a misfiring engine
