In this video Bernie visits a shop to to diagnose a P0016 Crankshaft Position – Camshaft Position Correlation Bank 1 Sensor A, As well as other related fault codes: P0300 Random Cylinder Misfire , P0301 Cylinder 1 Misfire, P0302 Cylinder 2 Misfire, P0304 Cylinder 4 Misfire. The vehicle a list of unrelated fault codes, including a P1523 Crash Signal from Airbag Controller: Implausible Signal. The VW CC was running poorly and misfiring. With the camshaft correlation fault code combined with engine misfires, it seemed right away it might be an engine timing issue. Bernie walks us through his diagnosis using an 8-channel scope as well as pressure transducers. He breaks down the waveform data as well as how to determine if camshaft / crankshaft correlation if out of spec by using rules of thumb for cam / crank degree relation. In the end, Bernie finds a faulty spool valve assembly using his data, then illustrates the specific failure by removing the faulty spool valve assembly and comparing it to a new one.
