P2117 — Throttle/Pedal Position Sensor "F" Minimum Stop Performance

powertrain (engine/transmission)

Is it safe to drive?

Drive with caution Drive with caution. Many throttle faults put the car into limp mode with limited power — enough to reach a shop, not for highway trips. If the engine stalls or the pedal stops responding, do not drive.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm P2117 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the throttle and intake air metering for damage, corrosion, chafing or poor contact.
  4. Subsystem check Inspect and clean the throttle body; check that the plate moves freely.
  5. Subsystem check Watch throttle position and MAF/MAP readings in live data while pressing the pedal — values should change smoothly.
  6. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2117 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2117 (parts and labor, USD, independent shop rates): Replace the throttle body assembly: $250–$700; Replace the MAF or MAP sensor: $150–$400; Clean the throttle body: $80–$200. Overall, fixing P2117 usually costs between $80 and $700. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

What are the symptoms of P2117?

Drivers most often notice: unstable or high idle, Check Engine Light on, poor throttle response, limp-home mode with reduced power.

How much does it cost to fix P2117?

Replace the throttle body assembly — $250–$700; Replace the MAF or MAP sensor — $150–$400; Clean the throttle body — $80–$200. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

Will P2117 clear itself?

Sometimes P2117 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

What does OBD2 code P2117 mean?

Throttle/Pedal Position Sensor "F" Minimum Stop Performance (P2117): a powertrain (engine/transmission) fault affecting the throttle and intake air metering. Short, gentle driving to a shop is usually possible. Most often caused by wiring or connector faults in the throttle circuit, faulty throttle position sensor or pedal sensor, failed electronic throttle motor.

What does P2117 mean?

The engine control module sets P2117 when it detects a fault in the throttle and intake air metering. In practical terms: throttle/pedal position sensor "F" minimum stop performance. The code belongs to the powertrain (engine/transmission) group of OBD2 codes.

To set P2117, the control module compares live readings of the throttle and intake air metering against calibrated limits, usually over several drive cycles. Alongside the code it stores a freeze frame — a snapshot of rpm, load, coolant temperature and vehicle speed at the moment of failure. Reading that snapshot first saves diagnostic time.

What causes P2117?

  • intake air leaks after the MAF sensor
  • failed electronic throttle motor
  • contaminated or failed MAF/MAP sensor
  • faulty throttle position sensor or pedal sensor
  • wiring or connector faults in the throttle circuit

Common symptoms of P2117

  • unstable or high idle
  • Check Engine Light on
  • poor throttle response
  • limp-home mode with reduced power
  • stalling when coming to a stop

How to fix P2117

Start with the cheapest and most common causes before replacing expensive parts:

  • Replace the throttle body assembly — $250–$700
  • Replace the MAF or MAP sensor — $150–$400
  • Clean the throttle body — $80–$200

Can you drive with P2117?

Drive with caution. Many throttle faults put the car into limp mode with limited power — enough to reach a shop, not for highway trips. If the engine stalls or the pedal stops responding, do not drive.
