P0951 code meaning
Auto Shift Manual Control Circuit Range/Performance
What P0951 means
Plausibility fault in the circuit that reports the driver's manual upshift and downshift requests, typically the tip gate of an automatic selector lever or steering wheel paddles. The signal is electrically valid but makes no sense, for example both requests active together or a request held far longer than any tap. A Volkswagen patent explains that the Hall elements in such tip gates are hard to diagnose and proposes checking all sensors and lines while the lever sits in P or R. No manufacturer documents this exact code publicly; CARB requires rationality checks on such inputs. P0950 is the general circuit fault, P0952 to P0954 the low, high and intermittent faults. Usually only manual shifting is disabled.
P0951 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 repairAfter a drive cycle
Symptoms of P0951
- Tip shifting or paddles do not respond or respond erratically
- Unwanted gear changes in manual mode
- Warning message, automatic mode keeps working
Common causes of P0951
- Most likelySticking or worn up/down tip switch, request signal stays active
- PossibleDisplaced magnet or damaged Hall sensor board in the selector lever
- PossibleSpilled liquid or dirt in the shifter causing cross-talk between contacts
- Less likelyFaulty input stage in the transmission or shifter control module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0951 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. |
| 51 | The exact fault in that area. |
What to do next
- Note P0951 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 P0951
What does P0951 mean?
P0951 means "Auto Shift Manual Control Circuit Range/Performance". Plausibility fault in the circuit that reports the driver's manual upshift and downshift requests, typically the tip gate of an automatic selector lever or steering wheel paddles. It is a generic code, so it means the same on every make.
Is it safe to drive with P0951?
P0951 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0951 fail an emissions test?
P0951 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 P0951 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 P0951 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
