What Does P210E Mean?
The PCM has detected a mismatch between throttle position sensor signals and accelerator pedal position sensor signals. The two sensor systems are not correlating properly, indicating one or both may be reading incorrectly.
Safety Warning
Vehicle may enter limp mode or experience unintended acceleration/deceleration. Creates extremely dangerous conditions due to unpredictable throttle behavior that doesn't match driver input.
Common Causes
35%
Faulty accelerator pedal position sensor providing incorrect signal
30%
Faulty throttle position sensor or throttle body malfunction
20%
Wiring issues causing voltage drop or interference in sensor circuits
15%
Low system voltage or charging system problems affecting sensor readings
Diagnostic Steps
1
Step 1: Using scan tool, monitor both accelerator pedal position and throttle position sensor values simultaneously at rest and during pedal application
2
Step 2: Check reference voltage (typically 5V) at both accelerator pedal and throttle position sensors
3
Step 3: Verify proper ground circuits for both sensor systems using voltage drop testing
4
Step 4: Test accelerator pedal position sensor by monitoring voltage sweep from idle to wide open throttle (should be smooth and proportional)
5
Step 5: Compare actual throttle blade position to sensor reading using visual inspection or mechanical gauge
Estimated Repair Cost
$150 - $800
Parts + labor, varies by vehicle and location
The PCM has detected a mismatch between throttle position sensor signals and accelerator pedal position sensor signals. The two sensor systems are not correlating properly, indicating one or both may be reading incorrectly.
The most common cause of P210E (Throttle/Pedal Position Sensor/Switch "C"/"F" Voltage Correlation) is: Faulty accelerator pedal position sensor providing incorrect signal
Typical repair costs for P210E range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
