Throttle/Pedal Position Sensor Minimum Stop Performance
Code P2117 indicates that the Engine Control Module (ECM) has detected a malfunction in the throttle or pedal position sensor circuit related to the minimum stop position. This typically means the sensor signal is out of expected range when the throttle is at idle or closed position, often due to a faulty sensor, wiring issues, or carbon buildup on the throttle body.
1. Most Common Causes
- Faulty accelerator pedal position sensor 'F'
- Loose or corroded connections in the sensor harness
- Sensor circuit shorted to ground or voltage
- Mechanical obstruction or carbon buildup preventing throttle plate from fully closing
- Dirty or damaged electronic throttle body (ETC)
- Internal PCM failure
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or limp mode
- Poor idle or stalling
- Unresponsive or delayed throttle response
3. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm code P2117 and check for related codes.
Step 2: Visually inspect wiring and connectors for damage, corrosion, or loose connections.
Step 3: Test throttle position sensor and accelerator pedal position sensor with a multimeter per manufacturer specs.
Step 4: Clean throttle body if carbon buildup is present, then recalibrate if necessary.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended as it can cause reduced engine power, stalling, or unresponsive throttle, leading to unsafe driving conditions.
How much does it cost to fix?▼
Repair costs typically range from $50 to $150 for sensor replacement or cleaning, but may be higher if wiring repairs are needed.
