P0340 Fault in Plymouth Neon: Camshaft Position Sensor A Bank 1 Circuit Malfunction Diagnosis and Repair Cost
While driving today, my check engine light activated, followed by noticeable engine hesitation and reduced performance a few miles later. I recently replaced all spark plugs and ignition wires, but the issue persisted—previously, the car exhibited shifting problems. After connecting the OBD2 scanner, I received diagnostic code P0340: Camshaft Position Sensor A - Bank 1 Circuit Malfunction. Given this error, I'm seeking clarification on what component to replace in my Plymouth Neon and whether the repair will be expensive or manageable without major costs. Any insights into common causes or troubleshooting steps would be greatly appreciated.
The camshaft position sensor is likely the culprit. It's located at the end of the camshaft on the driver's side of the engine, just below the valve cover. Oil leaks from its o-ring are common and can cause intermittent failures. However, without knowing the exact model year or engine type, I can't provide more specific guidance.
