P2115 — Throttle/Pedal Position Sensor "D" 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 P2115 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 P2115 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2115 (parts and labor, USD, independent shop rates): Clean the throttle body: $80–$200; Replace the throttle body assembly: $250–$700; Replace the MAF or MAP sensor: $150–$400. Overall, fixing P2115 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 does OBD2 code P2115 mean?

Throttle/Pedal Position Sensor "D" Minimum Stop Performance (P2115): 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, dirty throttle body or stuck throttle plate, failed electronic throttle motor.

What are the symptoms of P2115?

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

How do I diagnose P2115 myself?

Start with a scan: confirm P2115, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the throttle and intake air metering, and verify the suspect component against live data before buying parts.

Is it safe to drive with P2115?

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 much does it cost to fix P2115?

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

What does P2115 mean?

Behind P2115 is a specific failure in the throttle and intake air metering: throttle/pedal position sensor "D" minimum stop performance. The onboard computer stores it in the powertrain (engine/transmission) group after verifying the fault over repeated checks.

The module monitors this system continuously while driving. When readings fall outside the expected range for a defined number of drive cycles, it stores P2115 and switches on the warning light. Freeze frame data saved with the code shows the exact conditions — rpm, load, temperature, speed — at the moment the fault was detected, which is the best starting point for diagnosis.

Common symptoms of P2115

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

What causes P2115?

  • faulty throttle position sensor or pedal sensor
  • failed electronic throttle motor
  • contaminated or failed MAF/MAP sensor
  • intake air leaks after the MAF sensor

  6. Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2115 does not return.

How to fix P2115

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

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

Can you drive with P2115?

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.
