DTC P0850: Notes
DTC P0850 [AJ] DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P0850 |
Neutral switch input malfunction |
| DETECTION CONDITION |
- The PCM monitors changes in input voltage from the neutral switch. If the PCM does not detect voltage changes at PCM terminal 2X voltage when running the vehicle at a vehicle speed of 30 km/h {18.6 mph} or above
clutch pedal turns press and depress 10 times
repeatedly, the PCM determines that the neutral switch circuit has a malfunction.
Diagnostic support note
- This is a continuous monitor (CCM).
- MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
- PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA is available.
- DTC is stored in PCM memory.
