Throttle/Pedal Position Sensor Minimum Stop Performance
The P2114 code indicates that the Powertrain Control Module (PCM) has detected a malfunction in the throttle/pedal position sensor circuit, specifically that the sensor is not reading the minimum stop position correctly. This typically occurs when the throttle plate fails to return to its idle position or the pedal position sensor does not match the expected voltage at idle. The system uses two sensors (APP and TP) for redundancy; a discrepancy between them triggers this code. Common causes include a dirty throttle body, faulty throttle position sensor, accelerator pedal position sensor, or wiring issues.
1. Most Common Causes
- Dirty throttle body causing sticking
- Faulty throttle position sensor (TPS)
- Faulty accelerator pedal position sensor (APP)
- Wiring or connector issues in the sensor circuit
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: Scan for codes and record freeze frame data.
Step 2: Visually inspect throttle body for carbon buildup; clean if necessary.
Step 3: Test throttle position sensor and accelerator pedal position sensor voltages with a multimeter.
Step 4: Check wiring and connectors for damage, corrosion, or loose connections.
Step 5: If sensors are faulty, replace them and clear codes; test drive to verify repair.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive with P2114 as it can cause sudden loss of throttle control or stalling, leading to unsafe driving conditions. Limp mode may limit speed, but you should have it diagnosed and repaired promptly.
How much does it cost to fix?▼
The cost to fix P2114 typically ranges from $50 to $150 for cleaning the throttle body or replacing a sensor, but can be higher if wiring repairs or multiple parts are needed. Labor costs vary by shop.
