P0347 Fault Code

Camshaft Position Sensor A Circuit Low Input (Bank 2)

• What does that mean?
• Symptoms
• Causes
• Solutions

The P0347 fault code indicates a problem with the camshaft position sensor for Bank 2. This sensor plays a crucial role in the engine management system by providing the engine control unit (ECU) with information about the position of the camshaft in relation to the crankshaft. When the signal from this sensor is too low, it can disrupt the timing of engine operation, leading to poor performance and drivability issues.

• Camshaft Position Sensor A Circuit Low Input
• Relevant for vehicles with multi-cam configurations
• Affects timing and synchronization for optimal engine performance.

What are the symptoms of the P0347 code?

Drivers may experience various symptoms, such as:

• Check engine light illuminated on the dashboard
• Reduced engine performance or power loss
• Difficulty starting the engine
• Rough idling or stalling
• Increased fuel consumption

What causes the P0347 code?

Several issues can trigger the P0347 code, including:

• Faulty camshaft position sensor
• Shorted wiring or poor connection to the sensor
• Damaged or corroded connectors
• Issues with the timing belt/chain
• Problems with the engine control module (ECM)

How to fix P0347?

To resolve the P0347 fault code, follow these steps:

• Perform a visual inspection of the camshaft position sensor and wiring for damage or disconnections.
• Test the camshaft position sensor with a multimeter to check for proper resistance and voltage output.
• Replace the camshaft position sensor if it is found to be defective.
• Repair any wiring issues or corroded connectors as necessary.
• Clear the fault codes and conduct a test drive to ensure the issue is resolved.
