Technical Definition:

Camshaft Position (CMP) (Sensor A) Circuit Range / Performance (Bank 1) or Single Sensor

Technical Description:

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

Possible Causes:

• 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 Symptoms:

• Poor fuel economy
• Possible no start condition

Possible Solutions:

• 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.
