- The following conditions may cause the malfunction to occur:
- A short to voltage on the 5 volt reference circuit
- A short to ground on the 5 volt reference circuit
- An open in the 5 volt reference circuit to the position sensor
- A short to voltage on the position sensor signal circuit
- A short to ground on the position sensor signal circuit
- An open in the position sensor signal circuit
- An open in the position sensor low reference circuit
- A malfunctioning position sensor
- A disconnected, bent or damaged sensor link
IMPORTANT:
Before proceeding with the diagnosis do a visual inspection of the mechanical aspects of the sensor and its components. Ensure the sensor and the sensor link is not bent, disconnected, or insulation on wires are not rubbed through or damaged in any way.
If DTC C0870 is present, repair the malfunction for this DTC before diagnosing DTC C0615, C0620, C0625 or C0630.
