Genuine SINOTRUK 811W25970-6103 electronic accelerator pedal for C7H, C5H, T5G, T7H trucks. OEM replacement with full ECU compatibility.
When your SINOTRUK HOWO hesitates on acceleration or surges unexpectedly at low speed, don’t jump straight to fuel pumps or injectors — the issue might be simpler: a failing electronic accelerator pedal, like the original 811W25970-6103 used across C7H, C5H, T5G, and T7H models.
This genuine SINOTRUK pedal isn’t just a foot lever — it’s a precision sensor module that communicates your throttle input directly to the engine control unit (ECU). Using dual redundant potentiometers, it sends real-time voltage signals that determine fuel delivery, turbo boost, and transmission shift points. That means even minor wear or signal drift can cause poor drivability, reduced fuel efficiency, or unexpected limp mode activation.
Manufactured to exact factory specifications, this OEM pedal features sealed electronics resistant to dust, vibration, and humidity — critical for operations in African mines, Southeast Asian ports, or freezing Siberian highways. The pivot mechanism is pre-lubricated for smooth return action, and the rubber pad is anti-slip for driver comfort during long shifts.
Unlike cheap aftermarket copies that fail within weeks or send erratic signals, the original 811W25970-6103 maintains stable output across its entire range, ensuring seamless integration with the Bosch or SINOTRUK ECU systems. It also supports automatic calibration — no manual coding needed in most cases.
We’ve seen too many operators waste hours diagnosing “engine faults” only to find the root cause was a $120 pedal they tried to save money on. This one works right out of the box — every time.

Always disconnect the battery before replacing the electronic accelerator pedal — this prevents voltage spikes that can damage the ECU. Remove the lower dash cover to access the pedal assembly. Unplug the sealed 4-pin connector carefully — check for corrosion or bent pins. Unscrew the three mounting bolts (usually 10mm) and remove the old unit without forcing it. Install the new 811W25970-6103 pedal squarely and hand-tighten bolts before final torque (15–18 Nm). Reconnect wiring securely and apply dielectric grease to prevent moisture ingress. After reconnection, turn the ignition ON (engine off) and wait 10 seconds for the ECU to auto-calibrate the pedal position sensor. Do not press the pedal during this phase. Start the engine and test response at idle — smooth increase in RPM indicates correct setup. If the check engine light appears, use a diagnostic tool to clear any stored codes.
