Circuit Description
WARNING: This page is about a different car, the 2007 Isuzu i-370, 2007 GMC Canyon, and 2007 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.
The powertrain control module (PCM) uses the crankshaft position (CKP) sensor and the exhaust camshaft position (CMP) sensor information to monitor the correlation between the crankshaft and camshaft positions. If the PCM detects a CMP sensor pulse occurs during the incorrect CKP DTC P0017 will set.
