P2116 code meaning
Throttle/Pedal Position Sensor E Minimum Stop Performance
Powertrain system Generic code P21xx codes Check engine light
What P2116 means
The code covers the rest-position check of signal E. Ford, GM and Mitsubishi assign E to the second accelerator pedal sensor, which on many pedals runs at roughly half the voltage of sensor D (GM: APP 2 between 0.16 and 2.3 V). If the reading with the pedal released lies outside the learned or calibrated window, P2116 can be stored. No manufacturer documents this code publicly. Circuit faults of the same sensor are reported separately (P2125, P2127-P2129) and disagreement between D and E as P2138; P2115 and P2117 handle D and F. Typical effects are a warning lamp, an unsteady idle and limited throttle response.
P2116 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 P2116
- Warning lamp on
- Unsteady or raised idle
- Limited throttle response
Common causes of P2116
- Most likelyPedal held off its stop by floor mat or sticking pivot
- PossibleWorn or contaminated sensor track E
- Less likelyMoisture or corrosion at the 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 P2116 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. |
| 16 | The exact fault in that area. |
What to do next
- Note P2116 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 P2116
What does P2116 mean?
P2116 means "Throttle/Pedal Position Sensor E Minimum Stop Performance". The code covers the rest-position check of signal E. It is a generic code, so it means the same on every make.
Is it safe to drive with P2116?
Drive gently and only to a workshop. With P2116 the car can go into limp mode (reduced power) to protect itself.
Will P2116 fail an emissions test?
Yes, it can. P2116 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 P2116 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 P2116 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
