Genuine 78110-0C012 Accelerator Pedal Position Sensor Assembly

The Genuine 78110-0C012 Accelerator Pedal Position Sensor Assembly is a factory OEM component designed for Toyota vehicles equipped with electronic drive-by-wire throttle control systems. This sensor assembly measures accelerator pedal position and communicates that data to the engine control module (ECM) to precisely control throttle opening, air-fuel mixture, and engine performance.

Key Features:

• Genuine Toyota OEM part number 78110-0C012 (supersedes 78110-0C010 and 78110-0C011)
• Complete accelerator pedal sensor assembly with integrated pedal
• Dual potentiometer design for redundancy and fail-safe operation
• Electronic drive-by-wire system eliminates mechanical throttle cables
• Provides voltage signal ranging from 0.5V (pedal released) to 4.5V (full throttle)
• Direct replacement for worn or failed accelerator pedal sensors
• Factory-tested for reliability and durability

This accelerator pedal position sensor is an integral component of modern electronic throttle control systems. When you press the accelerator pedal, the sensor converts pedal movement into electronic signals that the powertrain control module uses to calculate optimal throttle position, fuel delivery, ignition timing, and transmission shift points. The dual-sensor design ensures safe operation—if one sensor fails, the backup sensor maintains functionality while triggering a diagnostic code.

Important Installation Notes: This is a complete pedal assembly with integrated sensors. Do not drop or strike the accelerator pedal during installation. Always disconnect the negative battery cable before removal. Some vehicles may require pedal position relearning procedures after installation.
