What to do when the Volkswagen car shows fault code p0343?
1 Answers
Volkswagen New Bora shows fault code p0343 due to: the camshaft position sensor signal is too high. If this fault code appears, do not rush to replace the sensor. The correct detection methods are introduced as follows: 1. System check: Ensure the timing system is correctly installed with no timing chain skipping. 2. Component check: The control components of the variable timing system work normally, the actuator operates smoothly without sticking or malfunction, the hydraulic components maintain normal oil pressure, the oil passages are clear, and the belt gear and shaft's fixed key show no displacement or fracture. 3. Fault check: Sensor malfunction. If possible, use an oscilloscope for waveform testing. Check for sensor control circuit faults, such as short circuits or open circuits, use an ohmmeter to test the connection status of the circuit, and verify whether the input and output signal values are within the standard range.
