How To Fix a P0340 Code Mitsubishi Galant Camshaft Position Sensor

A bad Camshaft Position Sensor will cause a vehicle to not start at times and other times work intermittently.

What is a P0340 Code on a 2001-2005 Mitsubishi Galant?

A P0340 Code is a “Camshaft Position Sensor Circuit Malfunction”.

This usually is a failed Camshaft Position Sensor, wiring, or harnesses.

Symptoms of a P0340 Code on a 2001-2005 Mitsubishi Galant

• No Start
• No Spark
• Intermittent shut downs

The most common symptom of a Mitsubishi Galant P0340 Code is a failed Camshaft Position Sensor which causes no spark to be sent to the spark plug.

This will cause the vehicle to not start until the issue is fixed.

In some cases, the Camshaft Position Sensor may be a wiring issue that is causing a problem.

Wiring issues can cause intermittent shutdowns since the sensor data will not be sent to the onboard computer (ECM).

Camshaft Position Sensor Location 2001-2005 Mitsubishi Galant

The Camshaft Position Sensor is located at the back of the cylinder head at the top.

The sensor is held in place with a 10mm bolt.

Besides a new sensor only a 10mm wrench or socket is needed to replace the Camshaft Position Sensor.

How To Replace the Camshaft Position Sensor on Mitsubishi Galant

1. Remove the wiring harness.
2. Remove the 10mm bolt holding it in place.
3. Remove the old sensor.
4. Insert the new sensor.
5. Tighten the 10mm bolt.
6. Attach wiring harness
7. Test the vehicle.

Summary
Replacing the Camshaft Position Sensor on Mitsubishi Galant is a fairly easy task that most DIY mechanics can do.

All that is needed to replace the sensor is a 10mm wrench and a new sensor.

Of course, if in doubt, be sure to call a professional.

Keep in mind a bad wiring connection can cause the same issues as a bad sensor.

The harness and wiring should be examined to see if there are any opens or shorts.

A multi meter can also be used to test voltages and continuity of the wires going to the cam sensor.
