What Does Trouble Code P0341 Mean?

The camshaft position (CMP) sensor is designed to sense the 1X reluctor wheel on the camshaft.

When the tooth of the reluctor wheel passes underneath the CMP sensor, it produces an ON/OFF voltage signal that is sent directly to the fuel injection computer.

A trouble code P0341: Camshaft Position (CMP) Sensor Performance Problem is set when:

• The CMP sensor stops producing its CMP signal.
• A problem occurs in the CMP signal circuit wire (between the CMP sensor and the fuel injection computer).

Common Symptoms Of A P0341 Trouble Code

A failure of the camshaft position sensor will cause one or more of the following symptoms:

• Extended cranking time (engine takes longer than usual to start).
• Lack of power when accelerating engine under load.
• Engine may stall after starting.
• Check engine light illuminated on the instrument cluster.
• Trouble code P0341 registered.

What Does The Camshaft Position Sensor Do?

As previously mentioned, the camshaft position sensor monitors and reports the position and rotation of the camshaft to the fuel injection computer.

The camshaft position sensor does this by monitoring a tooth on a reluctor wheel on the rear of the camshaft.

When the tooth (on the reluctor wheel) passes under the camshaft position sensor, it produces a pulsing ON/OFF voltage signal.

The fuel injection computer then uses the camshaft position sensor signal info to:

• Determine if the pistons are on their compression (firing) or exhaust stroke.

What Causes A P0341 Trouble Code?

The most common cause of a trouble code P0341 is a bad camshaft position sensor, but not always.

Other things that can cause a P0341 trouble code are:

• Damaged CMP sensor connector making a poor connection.
• Damaged camshaft reluctor wheel.
• CMP sensor coming in contact with the reluctor wheel.
• Wiring harness problem causing tension on the CMP sensor connector.

How To Diagnose And Repair A P0341 Trouble Code

You can troubleshoot and repair a trouble code P0341 by testing the camshaft position sensor to see if it's bad (or not).

The camshaft position sensor test involves:

• Making sure that the CMP sensor is receiving 12 Volts from the fuel injection computer.
• Making sure that the CMP sensor is receiving Ground from the fuel injection computer.
• Making sure that the CMP sensor is producing its CMP 1X signal.

You can correctly conclude that the CMP sensor is bad, and needs to be replaced, if:

• The CMP sensor is receiving 12 Volts from the fuel injection computer.
• The CMP sensor is receiving Ground from the fuel injection computer.
• The CMP sensor IS NOT producing its CMP 1X signal.
