The trouble code P0017 is an indicator of the trouble in the car and it shows for the Crankshaft Position Camshaft Position Correlation. The symptoms of the problem also related with roughness when accelerating with condensed fuel economy and engine act. A code will be kept in the PCM and the malfunction indicator lamp will be lit up. The most common causes are imperfect timing belt or chain alignment, damaged tone rings, crank sensors or faulty cam, faulty connectors, or faulty PCM.
