P0341 Code: Meaning, Symptoms, Causes & Fixing

The camshaft position sensor is one of the most important sensors of the internal combustion engine. It monitors the position and motion of the camshaft. It records data related to the camshaft and sends this data to the powertrain control module (PCM). The PCM triggers the P0341 when the camshaft sensor does not accurately measure the position of the camshaft. This article mainly explains the P0341 code meaning, symptoms, and causes.

P0341 Code Definition

P0341 code stands for “Camshaft Position Sensor “A” Circuit Range/Performance (Bank 1 or Single Sensor).”

What Does the P0341 Code Mean?

The P0341 code indicates that your powertrain control module (PCM) has detected a problem with the signal coming from the Camshaft Position Sensor.

It’s important to note that this code won’t be set unless the cam sensor signal goes away.

P0341 code

The main function of the camshaft position sensor is to calculate the rotational speed of the camshaft. During the rotation, the camshaft position sensor also records the exact position of the camshaft. This sensor sends the camshaft information to the PCM.

Accurate camshaft position sensor reading is important for advanced IC engines to achieve optimum efficiency. These readings play a vital role in fuel injection timing and ignition timing. The fuel injection timing and ignition timing may be affected by the accuracy of the data received.       

The signal from the engine’s camshaft position sensor is the main source of information for all engine speed-related statistics in many contemporary automobiles.

PCM uses the camshaft position sensor information to adjust the fuel ignition timing and fuel injection system timing. When your PCM detects a wrong signal from the cam sensor, it triggers the P0341 code.

Causes of the P0341 Code

  • Bad or damaged camshaft position sensor
  • Damaged camshaft position sensor circuit wiring
  • Engine misfiring
  • Damaged camshaft position sensor connectors
  • Bad crankshaft position sensor
  • Breakage in valve timing parts like damaged timing belts, damaged timing chain guides, or faulty timing sprockets
  • Bad camshaft reluctor wheel
  • Outdated PCM software
  • Fault in PCM

How to diagnose the P0341 Code?

  • Use an OBD2 scanner to confirm the presence of the P0341 code.
  • Use the freeze frame data to check what’s going on. Continue the troubleshooting based on the other trouble codes you may find.
  • Clear the codes.
  • Test drive your vehicle. If the P0341 code return, then move for further inspection.
  • Visually inspect the connectors of the camshaft position sensor.
  • Inspect the camshaft position sensor wiring
  • Inspect for any corrosion in the sensor connections.
  • Check the sensor reluctor wheel for damage on the camshaft or camshaft gear.
  • Use an oscilloscope to check the ohm signal or voltage of the camshaft sensor. It is essential to replace the camshaft sensor if the voltage values differ from the actual ones. 
  • Inspect the powertrain control module (PCM). Update the PCM software or replace it if needed.

Common P0341 Code Diagnostic Mistakes

  • Not properly inspecting and diagnosing the root cause of the problem
  • Not inspecting the wiring and connections before replacing the camshaft sensor.
  • Replacing the unnecessary parts
  • Not diagnosing and repairing other related trouble codes
  • Not clearing the PCM codes after fixing the code.

Repair Cost of P0341 Code

To fix or repair the P0341 code, you need one or more of the following repairs:

Camshaft sensor replacement$110 to $310 
Crankshaft sensor replacement$190 to $270 
Timing chain replacement$190 to $1000
PCM replacement$1100 to $1300 

FAQ Section

What repairs can fix the P0341 Code?

How serious is the P0341 Code?

The trouble code P0341 is considered a serious diagnostic trouble code. The car may fail to start if it has a P0341 code. It may lead to different drivability issues, such as low power and poor fuel economy. Driving with this code is very dangerous. So, this code can be unsafe and hence can create unexpected and dangerous incidents.

Ignoring this trouble code for a long period of time can cause damage to several parts of the engine.

Can I drive with the P0341 Code?

Yes, you can drive for a short distance with the P0341 code. However, you shouldn’t drive for a long distance with the P0341 code. Driving with this code is very hazardous because this code may reduce your engine power and may trigger your car in limp mode while driving on the highway.
