What Does P2130 Mean?
The PCM has detected a malfunction in Throttle/Pedal Position Sensor F circuit. This is a general circuit fault indicating the sensor signal is implausible or out of expected parameters.
Safety Warning
Vehicle will enter limp mode with significantly reduced power. May result in inability to accelerate normally, creating hazardous merging or passing situations.
Common Causes
35%
Accelerator pedal position sensor failure or internal circuit fault
30%
Damaged wiring or poor connection between pedal sensor and PCM
15%
Throttle body position sensor correlation fault with pedal sensor
12%
Loss of 5V reference voltage or sensor ground circuit
8%
PCM internal fault in sensor processing circuit
Diagnostic Steps
1
Step 1: Monitor all throttle/pedal position sensor voltages in live data and verify sensors track smoothly through range
2
Step 2: Inspect accelerator pedal sensor connector for damage, corrosion, or loose pins
3
Step 3: Measure 5V reference voltage at pedal sensor (should be 4.8-5.2V) and verify ground circuit has less than 0.5 ohms resistance
4
Step 4: Check signal wire voltage ranges at pedal sensor through full pedal travel (typically two sensors: 0.5-1.0V and 1.0-2.0V at idle)
5
Step 5: Compare pedal position sensor values with throttle body position to verify correlation is within specification
Estimated Repair Cost
$200 - $650
Parts + labor, varies by vehicle and location
The PCM has detected a malfunction in Throttle/Pedal Position Sensor F circuit. This is a general circuit fault indicating the sensor signal is implausible or out of expected parameters.
The most common cause of P2130 (Throttle/Pedal Position Sensor/Switch "F" Circuit) is: Accelerator pedal position sensor failure or internal circuit fault
Typical repair costs for P2130 range from $200 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle will enter limp mode with significantly reduced power. May result in inability to accelerate normally, creating hazardous merging or passing situations.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2130 to identify the root cause.
