Code P0341: Camshaft Position Sensor Circuit Range/Performance

Trouble code P0341 is set whenever the camshaft position sensor sends an inconsistent signal to the powertrain control module. As a matter of fact, this code frequently appears while an engine is running or during extended cranking periods. Some vehicles that do not have camshaft position sensors can still set code P0341 to indicate issues with coils, spark plugs or spark plug wires. Find out more about potential causes of an OBD-II scanner error code P0341 problem and get expert advice on how to clear this error code.

What Does the Code P0341 Mean?

This code indicates that camshaft position sensor readings do not correspond to powertrain control module specifications. This discrepancy often involves the number of pulses that are detected during a certain number of engine revolutions. A range/performance issue with the camshaft position sensor circuit may also be due to extended cranking. If a car or truck that does not have a camshaft position sensor sets code P0341 and other codes related to this part, ignition components such as coils or spark plugs could be faulty.

How Do I Test the Camshaft Position Sensor Circuit?

The camshaft position sensor is designed to signal Top Dead Center on the compression stroke. This sensor interacts with the crankshaft position sensor to regulate the opening of intake valves on each cylinder and fuel injection. A reluctor wheel attached to the camshaft passes by the camshaft position sensor to deliver the most accurate readings.

Make sure that camshaft position sensor wiring is not routed too close to coils or spark plugs. These ignition components can cause interference or part damage such as burning, chafing or melting over time. It is also important to make sure that no connections have corroded or become loose, as either condition can cause the connection to be lost intermittently and set code P0341. If the sensor and wiring appear to be in satisfactory working condition, try to take a close look at the reluctor wheel.

Depending on the make, model and engine type of a vehicle, it may be possible to look at the reluctor wheel attached to the camshaft through the cam sensor port. Otherwise, it may be necessary to remove the camshaft or intake manifold to clear the way for a visual inspection.

The most common indications of camshaft position sensor problems other than visual inspection and OBD-II diagnostic testing are a Check Engine malfunction indicator light or an engine that will not start. Depending on the underlying issues, the PCM may enable the engine to run in what is referred to as “limp-in” or “limp-home” mode with poor fuel economy.

How Do I Fix Trouble Code P0341?

If the camshaft position sensor is where the problem originates, trouble code P0341 may be cleared by replacing this part. Take the time to check a few surrounding components first in order to make sure that the problem is not being caused by wiring routed near secondary ignition components where it runs the risk of heat damage.

Depending on the condition of other camshaft-related components and engine parts, OBD-II code P0341 may be set along with similar trouble codes. Trouble codes P0340 through P0349 primarily describe camshaft position sensor circuit malfunctions. Codes P0365 through P0369 point toward other circuit issues. More than one code may be set at a time, depending on the most current sensor readings.

You may need to replace this sensor, do rewiring or even replace a damaged reluctor wheel in order to clear trouble code P0341. Fixing problems with the camshaft position sensor can make it possible for an engine to safely start and run at the intended level of fuel economy.

Be sure to consult your owner’s manual, a repair guide, an AutoZoner at a store near you, or a licensed, professional mechanic for vehicle-specific repair information. Refer to the service manual for specific diagnostic, repair and tool information for your particular vehicle. Always chock your wheels prior to lifting a vehicle. Always disconnect the negative battery cable before servicing an electrical application on the vehicle to protect its electrical circuits in the event that a wire is accidentally pierced or grounded. Use caution when working with automotive batteries. Sulfuric acid is caustic and can burn clothing and skin or cause blindness. Always wear gloves and safety glasses and other personal protection equipment, and work in a well-ventilated area. Should electrolyte get on your body or clothing, neutralize it immediately with a solution of baking soda and water. Do not wear ties or loose clothing when working on your vehicle.
