OBD-II Generic Error Code P0347: How to Fix It

Q: Can I drive with a P0347 code?

It is not recommended. The vehicle may experience stalling, rough running, or poor fuel economy, and continued driving could cause further engine damage.

Q: What causes P0347?

Common causes include a faulty camshaft position sensor, damaged wiring, loose connections, low battery voltage, or a skipped timing chain/belt.

Q: Will a bad camshaft sensor cause the car not to start?

Yes, if the ECM cannot detect camshaft position, it may prevent the engine from starting to protect engine components.

Q: How much does it cost to fix P0347?

DIY sensor replacement costs $30-$100 for the part. Professional repair, including diagnostics, ranges from $150-$400.

Q: Can a low battery cause P0347?

Abstract

Error code P0347 indicates that the engine control module (ECM) has detected a low voltage signal from the camshaft position sensor on bank 2. This sensor monitors the position of the camshaft relative to the crankshaft, and a low input can cause drivability issues like rough idling, stalling, or difficulty starting. The fix typically involves inspecting the sensor, wiring, and timing components.
