What Does P2132 Mean?
The PCM has detected a voltage signal from Throttle/Pedal Position Sensor F that is below the acceptable threshold. This indicates a short to ground or sensor internal failure causing low voltage output.
Safety Warning
Vehicle will enter limp mode immediately with no or minimal throttle response. Creates unsafe condition if fault occurs while driving in traffic.
Common Causes
40%
Accelerator pedal position sensor internal short to ground or failure
30%
Short to ground in APP sensor signal wire or damaged insulation
15%
Corroded or damaged connector pins at pedal assembly causing short
10%
Ground circuit fault or poor connection affecting sensor voltage
5%
PCM internal input circuit failure causing false low reading
Diagnostic Steps
1
Step 1: Inspect accelerator pedal connector for moisture, corrosion, or damaged pins that could cause shorting
2
Step 2: Disconnect pedal sensor and measure voltage on signal wire at PCM side (should read 5V if circuit is open/not shorted)
3
Step 3: Measure resistance between sensor signal wire and ground with pedal disconnected (should be infinite/OL)
4
Step 4: Check wiring harness routing for pinch points, especially where harness passes through firewall or near pedal bracket
5
Step 5: If wiring tests good, replace accelerator pedal assembly with integrated sensors
Estimated Repair Cost
$200 - $600
Parts + labor, varies by vehicle and location
The PCM has detected a voltage signal from Throttle/Pedal Position Sensor F that is below the acceptable threshold. This indicates a short to ground or sensor internal failure causing low voltage output.
The most common cause of P2132 (Throttle/Pedal Position Sensor/Switch "F" Circuit Low) is: Accelerator pedal position sensor internal short to ground or failure
Typical repair costs for P2132 range from $200 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle will enter limp mode immediately with no or minimal throttle response. Creates unsafe condition if fault occurs while driving in traffic.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2132 to identify the root cause.
