What P2115 means
Here the controller judges position signal D at the released (minimum) end of travel. On Ford and GM drive-by-wire systems D is the first accelerator pedal sensor, so the code means the pedal's idle reading is outside the expected window, for example because the pedal does not return fully or its sensor track has shifted. No manufacturer documents P2115 publicly; Ford and GM publish only circuit and correlation codes for D (P2120-P2123, P2138). P2116 and P2117 are the E and F counterparts, P2109 and P2113 refer to A and B. The engine may not return to idle cleanly, and the ECU may limit pedal response.
P2115 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyEasy, DIY possible
- Typical labor0.2 to 1 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2115
- Warning lamp on
- Engine does not drop to normal idle when the pedal is released
- Dull or limited pedal response
Common causes of P2115
- Most likelyPedal blocked by floor mat or weak return spring
- PossibleWorn pedal sensor track D at the idle end
- Less likelyAftermarket pedal tuning module or wrong pedal part
- Less likelyCorroded or loose pedal connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2115 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 1 | Area: fuel and air metering. |
| 15 | The exact fault in that area. |
What to do next
- Note P2115 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 P2115
What does P2115 mean?
P2115 means "Throttle/Pedal Position Sensor D Minimum Stop Performance". Here the controller judges position signal D at the released (minimum) end of travel. It is a generic code, so it means the same on every make.
Is it safe to drive with P2115?
Drive gently and only to a workshop. With P2115 the car can go into limp mode (reduced power) to protect itself.
Will P2115 fail an emissions test?
Yes, it can. P2115 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2115 to fix?
Difficulty: easy. A typical repair takes 0.2 to 1 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2115 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
