P0340 - Camshaft Position Sensor Circuit Malfunction
1. Check Wiring and Connections: Inspect the wiring and connections between the camshaft position sensor (CMP) and the engine control unit (ECU). Ensure there are no loose or damaged wires.
2. Replace the CMP sensor: If the wiring is intact, replace the camshaft position sensor.
P0335 - Crankshaft Position (CKP) Sensor Circuit Malfunction
1. Inspect Wiring: Check the wiring and connections between the crankshaft position sensor (CKP) and the ECU. Look for loose or damaged wires.
2. Replace CKP Sensor: If the wiring is intact, replace the crankshaft position sensor.
P00141 - Exhaust Camshaft Position Actuator Circuit Malfunction (Bank 1)
1. Inspect Wiring: Check the wiring and connections between the exhaust camshaft position actuator and the ECU. Ensure there is no damage to the wiring.
2. Replace Actuator: If the wiring is intact, replace the exhaust camshaft position actuator.
3. Check Oil Level: Ensure the engine oil level is correct as low oil can cause this issue.
4. Inspect Variable Valve Timing (VVT) Solenoid: If the above doesn't resolve the problem, check the VVT solenoid for proper function.
5. Consult a Mechanic: If the problem persists, it's best to consult with a qualified mechanic who can diagnose the exact issue and perform necessary repairs.
