P0341: causes, symptoms and repairs

The meaning of fault code P0341

DTC P0341 is set when the powertrain control module (PCM) recognises that the car's camshaft position (CMP) sensorsensor signal is out of the specified range. For example, the signal may not correlate to the one from the crankshaft position (CKP) sensor. The signal is supposed to indicate the position of the camshaft in car engine, which allows the control unit to adjust the timing of the fuel injection and ignition systems.

What causes code P0341?

  • A dead battery or low charge
  • A faulty starter motor
  • Corroded contacts in the connector, causing a bad connection
  • A damaged wiring harness or a short circuit between the CMP device and the PCM
  • Electromagnetic interference due to the sensor wires’ proximity to the spark plug wires, etc.
  • Damage to the reluctor wheel or worn teeth
  • A bad cam sensor
  • A stretched or worn timing belt or chain
  • Misaligned timing marks
  • A defective or dirty cam timing disc
Symptoms to look out for

  • Activation of the check engine light on the dashboard
  • A misfiring engine
  • Starting difficulties or extended cranking
  • Poor acceleration and jerking while driving
  • An increase in fuel consumption (if the engine is able to start)
  • Surging at low RPM or a rough idle
  • A loss of power
Recommended repairs

  • First, you will need to identify the cause of the fault. Running a diagnostic scan will help you to do this quicker. Simply connect an OBD2 scanner to the onboard computer via the vehicle’s data link connector port and scan for DTCs. Related codes include P0342, P0345, and P0349. The computer’s freeze frame data may also be useful.
  • Inspect the wiring thoroughly to check for breakages, loose connectors, misrouted wiring harnesses, and corrosion. Replace any components with visible signs of damage, such as cracked or fraying parts and fix any loose connections. Remove traces of corrosion from the connector contacts using special cleaning agents to restore their conductivity.
  • Check the CMP sensor for damage and make sure that it is installed properly. Examine the reluctor wheel to see whether there are any missing or broken teeth.
  • You can measure the internal resistance of the device using a multimeter. There are few methods for testing this, depending on the vehicle model and specifications. Consult the vehicle’s repair manual to determine whether this value is within the normal range. You can also use an oscilloscope to check its signal strength. If the readings show that the device is faulty, replace it.
  • Check whether the timing belt or chain needs to be replaced or the tension needs to be adjusted. It may also be necessary to change the oil if the vehicle has a hydrostatic tensioner. You may also need to realign the timing marks.
  • Make sure the starter motor and battery are in working condition so that the engine is able to start and enough power is being supplied to the vehicle’s electrical devices. In the case of a dead battery, buying a new car battery may be necessary.
Frequently Asked Questions (FAQ)

What does the code “P0341” mean?

It means that the camshaft position sensor “A” is malfunctioning. It is triggered by the control module when the signal transmitted is incorrect.

What causes it to appear?

In short, this is often caused by electrical faults, including wire damage, loose parts, interference and corroded contacts, a lack of power, or defective timing components.

Can I still drive my car if this occurs?

This is not recommended due to the potential severity of the fault. When the timing is affected, the ignition and mixing processes will be disrupted, causing misfires and other driveability issues. The CMP sensor’s input is critical for the engine to operate effectively.

Cars the fault code P0341 is most commonly found on

Fault code P0341 - Camshaft Position Sensor Circuit Range/Performance can occur with any car but is most often found on the following cars:
