Throttle/Pedal Position Sensor/Switch Circuit Malfunction
Code P2130 indicates a malfunction in the throttle/pedal position sensor/switch circuit, specifically a correlation error between the accelerator pedal position sensor and the throttle position sensor. This typically occurs when the PCM detects that the voltage signals from these sensors do not match expected values, often due to wiring issues, sensor faults, or throttle body problems. The system may enter a reduced power mode to prevent damage.
01. Most Common Causes
- Faulty accelerator pedal position sensor
- Faulty throttle position sensor
- Wiring or connector issues in the sensor circuit
- Carbon buildup on throttle body causing erratic sensor readings
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or limp mode
- Poor acceleration or hesitation
- Erratic idle or stalling
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to read freeze frame data and confirm code P2130.
Step 2: Visually inspect wiring and connectors for damage, corrosion, or loose connections.
Step 3: Test accelerator pedal position sensor and throttle position sensor voltage signals with a multimeter.
Step 4: Check for throttle body carbon buildup and clean if necessary.
Step 5: If sensors are faulty, replace them and clear the code.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive with this code as the vehicle may enter limp mode, reducing power and potentially causing unsafe driving conditions. Have it diagnosed promptly.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, depending on whether the issue is a sensor replacement, wiring repair, or throttle body cleaning.
