The P0395 fault code refers to the Camshaft Position Sensor B Circuit High Input for Bank 2. This means that the engine control module (ECM) has detected a voltage reading that is higher than expected from the camshaft position sensor B on bank 2. The camshaft position sensor is critical in monitoring the position of the camshaft to ensure proper timing of the engine's intake and exhaust valves. A malfunction in this sensor can lead to a variety of engine performance issues.

What are the symptoms of the P0395 code?

Symptoms associated with the P0395 code can vary but may include:

• Check Engine Light illuminated
• Rough idling or engine misfires
• Decreased engine performance
• Difficulty starting the vehicle
• Stalling while driving.

What causes the P0395 code?

Common causes of the P0395 code may include:

• A faulty camshaft position sensor B
• Damaged wiring or connectors in the sensor circuit
• A malfunctioning engine control module (ECM)
• Timing chain or belt issues
• Mechanical failure in the camshaft or related components.

How to fix P0395?

To fix the P0395 fault code, the following steps are recommended:

1. Use an OBD-II scanner to confirm the code and check for any additional codes.
2. Inspect the camshaft position sensor B and the wiring for any signs of damage or disconnection.
3. Test the sensor with a multimeter to ensure it is operating within specifications.
4. If the sensor is faulty, replace it with a new one.
5. Clear the fault codes and test drive the vehicle to see if the code reappears. If it does, further investigation may be necessary for issues related to the ECM or timing components.
