Sinotruk HOWO
| Attribute | Description |
|---|---|
| Part Name | Electric Throttle Pedal / Electronic Accelerator Pedal |
| Common Names | E-TP (Electronic Throttle Pedal), Sensor Pedal, Drive-by-Wire Pedal |
| Function | Converts driver’s foot pressure into an electrical signal sent to the Engine Control Unit (ECU) to regulate fuel injection and engine speed |
| Technology Type | Contactless or dual-potentiometer sensor design (typically Hall-effect or resistive type) |
| Signal Output | Dual analog voltage signals (e.g., 0.3–5V range) with defined relationship (e.g., 1:2 ratio) for safety redundancy |
| Mounting Style | Bolt-on bracket mounted under the dashboard on the firewall side |
| Compatibility | Designed for use with common rail, EUI, and electronically controlled diesel engines |
| Interface | Multi-pin waterproof connector (typically 4–6 pins) linked to vehicle CAN bus or engine harness |

| Parameter | Specification |
|---|---|
| Operating Voltage | 5V (reference from ECU), powered via engine control circuit |
| Output Signal Range | • Primary Sensor: 0.3V (idle) → 4.8V (full load) • Secondary Sensor: Follows proportional curve (e.g., double of primary) |
| Signal Type | Analog voltage output (some models support digital/PWM output) |
| Pedal Travel (Stroke) | Approx. 20°–30° angular rotation (varies by model) |
| Resistance Tolerance | ±1% to ±3% for consistent response |
| Sensor Configuration | Dual independent sensors for fault detection and safety compliance |
| Protection Rating | IP67 – Dust-tight and protected against temporary immersion |
| Operating Temperature Range | -40°C to +85°C (-40°F to +185°F) |
| Durability | Rated for over 1 million cycles (long-term reliability) |
| Weight | Approx. 0.8 – 1.3 kg |
| Materials | • Housing: High-strength engineering plastic (ABS/PC blend) • Shaft & Linkage: Stainless steel or reinforced nylon • Seals: NBR or silicone rubber |
| Return Mechanism | Integrated torsion spring ensures automatic return to idle position |
⚠️ WARNING: Never remove the old pedal while ignition is ON — may trigger ECU errors.
Park securely and apply parking brake.
Turn off ignition and disconnect battery negative terminal.
Wait 2 minutes for ECU capacitors to discharge.
Remove lower dashboard trim panel near pedals.
Ensure clear access to mounting area.
Take photo of current wiring and linkage.
Locate multi-pin connector at back of pedal.
Press release tab and unplug carefully.
Inspect pins for corrosion or bending.
Unscrew 3–4 mounting bolts (M6/M8 typically).
Gently pull out the unit — avoid damaging surrounding components.
Insert new pedal into position.
Align mounting holes and secure with original bolts.
Torque to manufacturer specification (~8–10 N·m).
Plug in electrical connector firmly until it clicks.
Reinstall trim panels.
Reconnect battery.
Turn key to ON (do not start engine).
Wait 10–30 seconds for ECU to detect new pedal.
Some systems require pedal learning procedure via diagnostic tool (e.g., Delphi DTS, KTS, SCN coding).
✅ Perform test drive:
Check smooth acceleration
Confirm no “Check Engine” light
Verify cruise control functionality (if equipped)
