P0340

Technical Definition:

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

Trouble Code: P0340
Address: 0x0340
System: Powertrain
Subsystem: Ignition System or Engine Misfire
Technical Description:

This indicates that a problem was detected in the camshaft position sensor circuit.

Possible Causes:
  • a wire or connector in the circuit could be grounded/shorted/broken
  • the camshaft position sensor may have failed
  • the PCM may have failed
  • there exists an open circuit
  • the crankshaft position sensor may have failed

Possible Symptoms:
  • Hard starting or no start
  • Rough running / misfiring
  • Loss of engine power

Possible Solutions:
  • Visually inspect all the wiring and connectors in the circuit
  • Check for continuity in the circuit wiring
  • Check the operation (voltage) of the camshaft position sensor
  • Replace the camshaft position sensor as required
  • Check the crankshaft position circuit as well
  • Replace circuit wiring and/or connectors as required
  • Diagnose/replace the PCM as required

P0341

Technical Definition:

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

Trouble Code: P0341
Address: 0x0341
System: Powertrain
Subsystem: Ignition System or Engine Misfire
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.
