P0341 Camshaft Position Sensor Circuit Range/Performance

Description and meaning of DTC p0341

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) detecteda problem with the camshaft signal. The camshaft position sensor (CPS) sendsa specific signal to the PCM for Top Dead Center on the compression stroke aswell as signals indicating the position of the cam sensor. This is accomplishedthrough 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 shouldbe, this code is set. NOTE: this code can also be set by extended cranking periods.

p0341 diagnostic trouble code symptoms

The car will likely run with this code set, as it is often intermittent andalso 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 symptomsother than: Poor fuel economy (if engine runs)Possible no start condition

DTC p0341 - possible 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

How to fix OBD-II diagnostic trouble code p0341

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'simportant 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, discolorationindicative 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 onlybe done by removing cam shaft or intake manifold (depending on engine design) If all checks out okay, then replace the sensor.
