VW Vr6 cam/crank timing
Hi, I've been fortunate enough to not have to mess with a vr6 too in depth before, but my time has come. I am getting a 16724 / P0340 cam position sensor malfuntion code. The chain tensioner, two guide rails, and cam sensor were replaced in 2010 at 99k miles. Now it has 116k. Im wondering if anyone has a waveform or any information on what the cam and crank signals should look like when properly timed. From what I see the cam wheel has 2 long teeth and 2 short teeth. I assume the cam sensor is supposed to be pulled to ground when a tooth is present? Can anyone verify this? I have a sensor coming, because the customer replaced the sensor, and it will get stuck either high or low, manipulating with a metal object. I have found 1 waveform in the archives relating to this, but it doesnt have 2 revolutions shown, so it is unclear how it is supposed to look. Here is what I am seeing, red arrows added to show crank missing tooth. Thanks for any help. [2001 Volkswagen Jetta GLS, ECM/Inputs/Outputs Waveform]
