P0341 Camshaft Position Sensor Circuit Range/Performance (Bank 1)

OBD-II Trouble Code Technical Description

Camshaft Position Sensor Circuit Range/Performance

What does that mean?

This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model.

This P0341 code basically means that the powertrain control module (PCM) detected a problem with the camshaft signal.

The camshaft position sensor (CPS) sends a specific signal to the PCM for Top Dead Center on the compression stroke as well as signals indicating the position of the cam sensor. This is accomplished through a reluctor wheel attached to the camshaft that passes by the cam sensor. Any time that the signal to the PCM is inconsistent with what the signal should be, this code is set. NOTE: this code can also be set by extended cranking periods.

Symptoms

The car will likely run with this code set, as it is often intermittent and also because the PCM can often operate the vehicle in "limp-in/limp-home" mode even with a cam sensor signal problem. There may be no noticeable symptoms other than:

  • Poor fuel economy (if engine runs)
  • Possible no start condition

    • Causes

    A code P0341 may mean that one or more of the following has happened:

  • Cam sensor wiring routed too close to spark plug wiring (causing interference)
  • Poor wiring connection at cam sensor
  • Poor wiring connection at PCM
  • Bad cam sensor
  • Damaged reluctor wheel

    • Possible Solutions

    NOTE: In some cases this engine code is generated on vehicles that do not actually have a camshaft position sensor. In those cases it basically means the engine is misfiring badly due to faulty spark plugs, spark plug wires, and often coils.

    Often relacing the sensor fixes this code, but not necessarily. Therefore it’s important to check the following:

  • Check that the wiring isn’t routed too close to any secondary ignition components (coil, spark plug wires, etc.)
  • Visually inspect the wiring at the sensor for any burn marks, discoloration indicative of melting or chafing
  • Visually inspect the cam sensor for damage
  • Visually inspect the reluctor wheel through the cam sensor port (if possible) for any missing teeth or any damage
  • If reluctor isn’t visible from outside the engine, visual test can only be done by removing cam shaft or intake manifold (depending on engine design)
  • If all checks out okay, then replace the sensor.

    "Delete Error Code Permanently, Disable DTC Error Code Function for p0341 in the ECU"

    In extreme cases, we even have the option to permanently remove the specific DTC p0341 and disable the function of the specific error code in the ECU. All other fault code functions will then continue to work to protect the engine. This is different from clearing an error code with a diagnostic device. We have the option to permanently remove the function of the specific error code, so that it never comes back. Also emergency running that occurs on the specific error code can be solved in most cases.

    Of course we prefer to first try to solve the cause of the error code, but sometimes the only solution is to permanently disable the DTC function of p0341.
