Pinpoint Test E : Gear Neutral Position Sensor Circuit Faults: Notes
WARNING: This page is about a different variant/trim than selected.
Refer to Electronic Engine Controls - 1.0L Fox GTDI for schematic and connector information.
Normal Operation and Fault Conditions
The gear neutral position sensor provides an input to the PCM. The PCM uses this input when controlling the auto-start-stop system. For more information on the auto-start-stop system refer to the owner's literature and REFER to: Starting System - System Operation and Component Description .
Diagnostic Trouble Code (DTC) Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P086A | Neutral Position Sensor "A" Circuit/Open | Sets in the PCM when the PCM senses higher than expected voltage on the gear neutral position sensor feedback circuit, indicating a short directly to voltage. |
| P086B | Neutral Position Sensor "A" Circuit Range/Performance | Sets in the PCM when the PCM does not detect current through the gear neutral position sensor and there are no other gear neutral position sensor circuit Diagnostic Trouble Codes (DTCs) set. |
| P086C | Neutral Position Sensor "A" Circuit Low | Sets in the PCM when the PCM senses lower than expected voltage on the gear neutral position sensor feedback circuit, indicating an open or a short directly to ground. |
| P086D | Neutral Position Sensor "A" Circuit High | Sets in the PCM when the PCM senses higher than expected voltage on the gear neutral position sensor feedback circuit, indicating a short directly to voltage. |
| P08AE | Neutral Position Sensor "B" Circuit Range/Performance | Sets in the PCM when the PCM does not detect current through the gear neutral position sensor and there are no other gear neutral position sensor circuit Diagnostic Trouble Codes (DTCs) set. |
| P08AF | Neutral Position Sensor "B" Circuit Low | Sets in the PCM when the PCM senses lower than expected voltage on the gear neutral position sensor feedback circuit, indicating an open or a short directly to ground. |
| P08B0 | Neutral Position Sensor "B" Circuit High | Sets in the PCM when the PCM senses higher than expected voltage on the gear neutral position sensor feedback circuit, indicating a short directly to voltage. |
| P08B2 | Neutral Position Sensor "A"/"B" Correlation | Sets in the PCM when the gear neutral position sensor "A" indicates a different gear than gear neutral position sensor "B". |
| P26C3 | Internal Control Module Transmission Range Sensor Performance | Sets in the PCM when the gear neutral position sensor "A" indicates a different gear than gear neutral position sensor "B". |
