Circuit/System Testing
1. Ignition OFF, disconnect the harness connector of the CPP sensor.
2. Ignition ON, observe the scan tool CPP sensor voltage parameter for 0.1-volt.
瀚慖f the voltage is below the specified value, replace the CPP sensor.
瀚慖f the voltage is above the specified value, replace the ECM.
Component Testing
1. Ignition OFF, disconnect the harness connector of the CPP sensor.
2. Measure the resistance between the signal terminal B and the low reference terminal A of the CPP sensor. Sweep the CPP sensor through the
entire range. The resistance should vary low to high and high to low without any spikes or dropouts.
瀚慖f the resistance is erratic with spikes or dropouts, replace the CPP sensor.
