P2116
Throttle/Pedal Position Sensor E Minimum Stop Performance
Throttle / pedal position
Generic OBD-II
High
What it means
P2116 means the "E" throttle or pedal position sensor is not reading correctly at its minimum (closed/rest) stop — the value the ECM expects at idle or with the pedal released is out of range. Because the ECM relies on this signal to control the electronic throttle, the fault often triggers reduced power or limp mode until the sensor or its wiring is repaired.
High
Can I keep driving? Drivable but limited — a pedal/throttle sensor fault often triggers reduced-power or limp mode, so expect weak throttle response until it is fixed.
Common symptoms
What you'll notice
- Check-engine light on, often with a reduced-power or wrench warning
- Reduced power output, sometimes limp mode
- Poor or erratic throttle response and hesitation
- Unstable idle
Common causes
Most likely first
- Faulty throttle/pedal position sensor ELikely
- Open or shorted throttle/pedal sensor wiring harnessCommon
- Poor electrical connection or corrosion at the sensor connectorCommon
- Dirty or carbon-filled throttle bore preventing the plate reaching its rest (minimum) stopLess often
- An obstruction stopping the pedal from returning fully (e.g. a jammed floor mat)Less often
- Faulty ECM (least likely)Less often
How to diagnose & fix
Work through it in order
- With the key on and engine off, check the sensor connector for a steady 5-volt reference and a good ground.
- Inspect the sensor wiring and connector for damage, corrosion, or loose pins.
- Clean the throttle bore and confirm the plate and pedal return fully to their rest position.
- Watch the sensor voltage on a scan tool through its full sweep, looking for dropouts at the closed position.
- Replace the throttle/pedal position sensor if the signal is out of spec, then clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2116?+
For short distances only. The car may drop into reduced-power mode, which makes merging and hills harder. Have it diagnosed before depending on it.
Can I just clear P2116?+
It clears, but if a sensor or wiring fault is present the code and limp mode come back quickly, so fix the cause first.
