P0952 code meaning
Auto Shift Manual Control Circuit Low
What P0952 means
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.
P0952 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0952
- Manual tip shifting inoperative
- Gear indicator shows no manual gear or a warning message
- Normal automatic driving in D still possible
Common causes of P0952
- Most 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
- Less likelyLow supply voltage to a Hall-type tip sensor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0952 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 9 | Area: transmission. |
| 52 | The exact fault in that area. |
What to do next
- Note P0952 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0952
What does P0952 mean?
P0952 means "Auto Shift Manual Control Circuit Low". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0952?
P0952 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0952 fail an emissions test?
P0952 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0952 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0952 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
