P0953 code meaning
Auto Shift Manual Control Circuit High
What P0953 means
Voltage on the manual up/down request circuit lies above its expected window. Common reasons are a signal wire shorted to battery voltage or, where the input is pulled up internally, a broken wire or a switch that never closes. A Volkswagen patent names a short to plus and a line break as faults its tip-gate diagnosis detects with the lever in P or R; a Chrysler patent shows the classic AutoStick-style gate with one switch for up and one for down. No manufacturer documents this exact code publicly; CARB requires circuit checks on such inputs. P0952 covers the low side, P0954 dropouts, P0950 the general fault. Manual shifting is usually disabled, automatic mode remains.
P0953 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 P0953
- Tip gate or paddles have no effect
- Warning or message about manual mode
- Automatic shifting continues normally
Common causes of P0953
- Most likelySignal wire shorted to a voltage-carrying wire in the shifter harness
- PossibleBroken wire or unplugged connector on a pulled-up input
- PossibleMissing ground of the tip switch or Hall sensor
- Less likelyFaulty input stage in the transmission 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 P0953 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. |
| 53 | The exact fault in that area. |
What to do next
- Note P0953 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 P0953
What does P0953 mean?
P0953 means "Auto Shift Manual Control Circuit High". Voltage on the manual up/down request circuit lies above its expected window. It is a generic code, so it means the same on every make.
Is it safe to drive with P0953?
P0953 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0953 fail an emissions test?
P0953 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 P0953 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 P0953 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
