Code P0341 is a possible reading from an OBD-II scanner that translates to Camshaft Position Sensor “A” Circuit Range/Performance. Your vehicle's computer will trigger this code when the camshaft position sensor sends a signal that deviates from the specifications of the powertrain control module (PCM). The signal could be incorrect or out of time.

You can diagnose and fix code P0341 from your garage if you know what to look for and how to respond. Learn more about the symptoms and causes of code P0341 and what you can do to correct them. 

Symptoms of P0341 Code

The camshaft position sensor must adhere to the PCM's specifications so that subsequent processes can occur in time. Otherwise, the engine may have trouble starting or fail to start. The check engine light may also engage, among other symptoms: 

  • The engine stalls or fails to start 
  • The engine has low power if it starts
  • The engine shudders and misfires during operation 
  • The vehicle struggles to accelerate 
  • Fuel economy decreases  
  • The vehicle shakes while idling

Causes of P0341 Code

The camshaft position sensor works alongside the crankshaft sensor to determine when the first cylinder reaches the top dead point. The P0341 engine code will engage when the camshaft position sensor and crankshaft sensor cannot tell if or when the first cylinder reaches that position. 

Code P0341 may trigger for numerous reasons:

  • Camshaft position sensor failure: The camshaft position sensor may fail due to loose wiring, grime buildup, moisture or debris. Improper installation can also prevent the sensor from accurately detecting and transmitting PCM pulses.
  • Circuit interference or damage: The camshaft position sensor's wiring must run far enough from the coils or spark plugs to avoid damage from heat and friction. Such damage can throw off the sensor's accuracy. The code may also occur if connections become loose or damaged.
  • Reluctor wheel damage: The reluctor wheel has notches that trigger the crankshaft position sensor as the crankshaft rotates. Damage to the notches can prevent the wheel from triggering the sensors. 
  • Timing chain or tensioner stretching: The timing chain must maintain tension to synchronize the camshaft and crankshaft. Losing tension will prevent the engine from producing sufficient power. 
  • Battery failure: A vehicle may trigger code P0341 when the battery dies because the engine needs power. 
  • Starter motor failure: The starter motor allows the engine to begin taking in air. Damage to the starter motor will cause the engine to click and fail to start when you turn the key.  

Diagnosing P0341 Code

If your vehicle exhibits any of the symptoms of camshaft position sensor malfunction, take it to a mechanic or use a code reader to see which code appears. After determining that code P0341 is displaying, you or a mechanic can inspect various components to determine which is causing the issue. 

  • Inspect the camshaft position sensor, connectors and wiring: The camshaft position sensor will fail if its wires break or if the connections corrode. Damage to the sensor itself will also prevent it from working. 
  • Test the camshaft's voltage: The camshaft position sensor needs at least 5 volts of electricity to operate correctly. Use a multimeter to test that it produces the full 5 volts. A faulty sensor will produce less than 5 volts, preventing it from sending a signal to the PCM. 
  • Inspect the reluctor wheel: The reluctor wheel needs its teeth intact to trigger the sensor. A bend in the wheel could also put it out of alignment. 

Fixing P0341 Code

The appropriate fix for code P0341 depends on the root issue that causes the code to engage. Here are a few different ways to fix the problems that trigger code P0341. 

Replace the Camshaft Position Sensor 

Replacing the camshaft sensor is the next step if code P0341 is present and you notice the component is damaged. You can purchase a camshaft position sensor online or from your local car shop. Follow these steps to replace your camshaft position sensor:

  1. Turn off the vehicle and wait for the engine to cool. 
  2. Disconnect the car's battery cable.
  3. Remove the engine cover, if present.
  4. Locate the sensor on the timing cover, cylinder head or beside the engine block.
  5. Unfasten the bolt and connector that connects the sensor to the engine. 
  6. Twist and remove the sensor. 
  7. Check that the O-ring is in place.
  8. Insert the new camshaft position sensor, then fasten all bolts and connectors. 

Replace the Reluctor Ring

To remove a damaged reluctor wheel, start by heating the wheel to 200 degrees Fahrenheit using an automotive torch. Heating the reluctor will expand it enough to slide off of the crankshaft without bending it. You can then tap the old reluctor ring off with a hammer. With the old reluctor off, heat the new reluctor wheel to 450 degrees Fahrenheit so it fits around the crankshaft. Slide the ring onto the jib, tap it into place and allow time to cool. 

Replace Corroded Camshaft Sensor Connections

You can repair your camshaft position sensor by replacing any damaged or corroded connectors. To get started, purchase a camshaft position solenoid connector online or from a local shop. Then, disconnect the existing connector's wires and install the new connector. Each connector has color-coded wires that simplify the installation process. 

How to Prevent Camshaft Position Sensor Damage 

Damage to the camshaft position sensor and its associated components often comes from the gradual buildup of residue and grime. You can prevent the P0341 code from triggering through regular maintenance. Clean your engine regularly or ensure your preferred mechanic cleans it. You or a mechanic should also check the status of all sensors during your vehicle's yearly inspection.
