How to Test & Fix P0340 Camshaft Position Sensor “A” Circuit Fault Code |Fix Engine Starting Problem

Hi There, You guys may have had difficulties many times to start the engine. You have the engine cranking but no start. One of the common problems is faulty camshaft position sensor. In this video I show you how to test the camshaft position sensor. I Also explain the sensor wiring diagram, I point to each wire, then I show you how to test each single wire on the cam sensor. After testing the wiring, because there is no internal resistance measurement for the cam sensor, I show you how to read the sensor output signal using an oscilloscope and how to diagnose the sensor operation by reading the sensor’s waveform. What is covered in this video: – Intake camshaft position sensor location – Camshaft position sensor wiring diagram analysis – Camshaft position sensor Power supply test – Camshaft position sensor Ground Circuit test – Camshaft position sensor Signal Circuit test – Camshaft position sensor removal & inspection – Camshaft sensor output signal (waveform) reading and test using an oscilloscope
