Kevin Treanor



This eLearning course identifies the different ignition inputs used by the PCM to trigger the ignition system. The different types of crankshaft position sensors (CKP) and camshaft position sensors (CMP) used by vehicle manufacturers are reviewed. Various locations of these components as well as Diagnostic Trouble Codes (DTCs) that can set when they fail are identified. We demonstrate what an intermittent CKP fault acts like through exploring a live vehicle demonstration captured on video. Several examples shown of bad components captured using both a scan tool and a digital storage oscilloscope (DSO) are shown.


Areas covered:
• Different types of CKP and CMP sensors used today
• Likely locations of these components on the vehicle
• Relationship of how these vital inputs are used by the vehicle’s Powertrain Control Module (PCM)
• Best avenue for testing for a particular CKP or CMP sensor related fault


By completing/passing this course, you will attain the certificate Garage Gurus Certificate
