P0952Auto Shift Manual Control Circuit Low
- Generic OBD-II code · Powertrain
- How the car detects it
- The control unit sees the voltage on the manual up/down request circuit below its expected window, typically a signal wire shorted to ground or a switch stuck in the grounded state. In many tip gates the moving contact switches to ground, as a Nissan patent shows, so a short to ground can mimic a permanently held request; a Volkswagen patent describes checking the Hall tip sensors for shorts and breaks while the lever is in P or R. No manufacturer documents this exact code publicly; CARB requires circuit checks on such inputs. P0953 is the high counterpart, P0950 the general and P0951 the plausibility fault. In practice manual shifting is locked out while D keeps shifting automatically.
- What you may notice
- Manual tip shifting inoperative
- Gear indicator shows no manual gear or a warning message
- Normal automatic driving in D still possible
- Likely causes
- LikelySignal wire of the up/down circuit chafed through and shorted to ground
- PossibleTip switch stuck in the closed position
- PossibleMoisture or spilled drink in the shifter creating a leakage path to ground
- RareLow supply voltage to a Hall-type tip sensor
- Repair
- Medium · Often possible to do yourself.Typical cost: €40 – €450
