How to Repair P0343 Trouble Code?

[Miranda]

p0343 trouble code means and repair methods are as follows: 1. This trouble code indicates that the camshaft position sensor signal voltage is higher than the calibrated maximum value. The function of the camshaft position sensor is to collect the position signal of the valve camshaft and input it to the ECU, so that the ECU can identify the compression top dead center of cylinder 1, thereby performing sequential fuel injection control, ignition timing control and knock control. 2. Check whether the engine oil is seriously dirty, if so, replace the engine oil; whether the camshaft position sensor and its circuit are faulty, whether the timing belt and other components are faulty, and whether the ECU is faulty; these faults need to be repaired by professional maintenance personnel. Usually, you should pay attention to changing the engine oil and oil filter on time.
