P2117 — Throttle/Pedal Position Sensor “F” Minimum Stop Performance #

Note: The label for DTC P2117 may vary by manufacturer.

• P2117: Throttle/Pedal Position Sensor “F” Minimum Stop Performance (Generic/Most OEMs)
• P2117: Throttle Actuator Control Throttle Body Range/Performance (Honda/Acura)
• P2117: Throttle Position Sensor “F” Performance Problem (Ford)
• P2117: Accelerator Pedal Position Sensor “F” Minimum Stop Out of Range (GM/Chevrolet)

Summary of code P2117 #

The P2117 diagnostic trouble code indicates that the engine control module (ECM) detected the Throttle/Pedal Position Sensor “F” is reporting a value outside the expected minimum stop range. The throttle/pedal position sensor is a key component of the electronic throttle control (ETC) system, which regulates how far the throttle plate opens in response to accelerator pedal input. When the “minimum stop” is mentioned, it refers to the lowest physical or electronic position the sensor should detect when the throttle is closed. If the ECM detects a signal that doesn’t match this calibrated stop, it sets P2117 to ensure the system operates safely. This code can cause drivability issues and may trigger the vehicle to enter “limp mode” to protect the engine.

Common symptoms for code P2117 #

When P2117 is stored, drivers may notice a range of symptoms affecting acceleration and throttle response. The severity can vary, but these issues are often hard to ignore and can dramatically impact daily driving.

• Check Engine Light illuminated
• Reduced engine power (limp mode)
• Difficult or delayed acceleration
• Unstable idle or engine stalling
• Poor throttle response or hesitation

Most likely causes of P2117 #

The causes of code P2117 generally stem from faults within the throttle body assembly or related circuits. Some are simple to check, while others may require more advanced diagnostics. Here are the most frequent sources, listed by likelihood:

1. Faulty throttle position sensor “F” (either internal failure or contamination)
2. Wiring issues—damaged, corroded, or loose connectors at the throttle body or ECM
3. Faulty throttle body assembly (internal mechanical or electronic problem)
4. Out-of-spec minimum stop adjustment (rare, but possible after throttle body cleaning or replacement)
5. ECM/PCM software or hardware failure (least common)

Step-by-step diagnostic procedure for P2117 #

Diagnosing P2117 requires a systematic approach to avoid unnecessary part replacements. Always start with the basics, then move to more technical checks:

1. Use an OBD-II scanner to confirm the presence of P2117 and check for related codes (especially other throttle or pedal sensor codes).
2. Inspect the throttle body and connector for signs of corrosion, moisture, loose pins, or damaged wiring. Repair as needed.
3. Test the throttle position sensor “F” with a multimeter or scan tool—look for smooth, stable voltage as the throttle is opened and closed.
4. Visually inspect the throttle plate for sticking, carbon buildup, or signs of tampering.
5. Clear the code and perform a throttle relearn/reset procedure (refer to OEM instructions).
6. If the problem persists, check for software updates or ECM/PCM failures.

Possible repairs for P2117 #

Repairs for P2117 should target the root cause identified in the diagnostic steps. Avoid guessing—each fix corresponds directly to the verified issue.

• Replace the throttle position sensor “F” (if faulty or out of range)
• Repair or replace damaged wiring or connectors in the throttle body circuit
• Clean or replace the throttle body if mechanical sticking or severe carbon buildup is found
• Correct minimum stop adjustment (if out of spec—use OEM procedures)
• Update or reprogram the ECM/PCM if a software issue is confirmed

Is it safe to drive with code P2117? #

Driving with P2117 is generally not recommended. If the vehicle enters “limp mode,” acceleration will be severely limited, making it unsafe in traffic or on highways. Unstable idle or stalling further increases the risk of losing control, especially in critical situations. Use extreme caution—if the engine runs roughly or the throttle response is inconsistent, have the vehicle towed or serviced as soon as possible.

Vehicles most commonly affected by P2117 #

While P2117 is a generic OBD-II code found on many vehicles, it is most frequently reported on models that use electronic throttle control systems from the following manufacturers:

• Honda/Acura (Civic, Accord, CR-V, MDX, etc.)
• Ford (Focus, Escape, Fusion, F-150, etc.)
• Chevrolet/GMC (Silverado, Malibu, Equinox, etc.)
• Toyota/Lexus (Camry, Corolla, RAV4, ES350, etc.)
• Nissan/Infiniti (Altima, Maxima, Rogue, QX60, etc.)
• Chrysler/Dodge/Jeep (Ram, Grand Cherokee, Charger, etc.)

Common mistakes and best practices for P2117 #

Misdiagnosing P2117 can lead to wasted time and money. Here’s how to avoid the most frequent pitfalls and ensure a correct repair:

• Do not replace the throttle body or sensor without confirming the fault; wiring and connector issues are common culprits.
• Always perform a throttle relearn/calibration after repairs—skipping this step can cause the code to return.
• Use OEM parts for sensor or throttle body replacement to avoid compatibility issues.
• Document all steps and verify repairs with a test drive and scan tool data review.

FAQ express — P2117 #

Q: Will disconnecting the battery clear P2117?
A: Disconnecting the battery may temporarily clear the code, but it won’t fix the underlying problem. The code will return if the root cause is not addressed.

Q: Do I need to replace the entire throttle body for P2117?
A: Not always. Sometimes, cleaning the throttle body or repairing wiring is enough. Replace the throttle body only if it is confirmed to be faulty after diagnosis.
