WG1641240114 Right Lower Pedal

The WG1641240114 Right Lower Pedal is a key operating part for SINOTRUK HOWO heavy-duty trucks' control systems (tractor, cargo, dump trucks). It acts as the accelerator pedal, transmitting the driver's acceleration intentions to the ECU via a precision sensor. This adjusts engine fuel injection linearly, ensuring smooth power output during startup, acceleration, or constant speed-super important for driving comfort, fuel economy, and stable operation. We use good materials and precise manufacturing to make it: the pedal arm is high-strength aluminum alloy-lightweight and corrosion-proof. The pedal pad is non-slip rubber-wear-resistant and anti-skid. The built-in sensor uses imported electronic components-stable signal transmission and anti-interference. The installation interface, fixed holes, and signal connector fit the original HOWO control system exactly (models with WP series engines), so it installs with no mods. It handles tough conditions--30℃~70℃ cab temperature, 50-100N stepping force, and dust/liquid splashing-without pedal arm deformation, rubber pad peeling, or sensor failure. Swapping it is easy: no need to modify the wiring harness, just disconnect the old pedal's sensor connector, take off the bolts, install the new pedal, reconnect the connector, and test acceleration. Before shipping, we test 'em strict: check sensor signal accuracy (error ≤±1%), durability (500k stepping cycles), and environmental adaptability-so it's reliable.

Product Model: WG1641240114

Applicable vehicles: HOWO A7/T7H/T5G (original HOWO control system, matching WP series engines)

Type: Right lower pedal (accelerator pedal; aluminum alloy + non-slip rubber + imported sensor)

Function: Transmit acceleration signals to ECU, adjust fuel injection, ensure smooth power output

Material: Pedal arm (high-strength aluminum alloy); pedal pad (non-slip wear-resistant rubber); sensor (imported electronics)

Installation: Direct replacement-fits original control system interface and signal protocol

Working conditions: -30℃~70℃; 50-100N stepping force; ≤±1% signal error; ≥400,000 km life

Sensitive & linear response: High-precision imported sensor + optimized pedal stroke ensure real-time signal transmission and linear power output. Response time ≤0.1 seconds, 25% faster than ordinary accelerator pedals.

Durable & reliable: High-strength aluminum alloy pedal arm resists deformation/corrosion, non-slip rubber pad is wear-resistant. Sensor service life up to 800k cycles, overall pedal lasts 400k+ km.

Perfect for HOWO: Made to HOWO's original control system design-installation interface, fixed holes, signal connector match. No adapters or wiring mods needed-saves 30% maintenance time vs universal accelerator pedals.

Comfortable & anti-slip: Ergonomic pedal angle + non-slip pad increase foot contact area, reduce long-distance driving fatigue, and avoid slipping in wet conditions.

This Right Lower Pedal (Model: WG1641240114) is only for SINOTRUK HOWO heavy-duty trucks-A7, T7H, T5G models with original HOWO control systems (matching WP series engines). It won't work on HOWO with modified control systems or other brands (FAW Jiefang, Dongfeng Tianlong). Those have different control system structures, interfaces, or signal protocols-this right lower pedal won't fit or work.

Q1: Works on HOWO with modified control systems?

A1: No-modified control systems have different structures/signal protocols. It causes mismatched installation or abnormal signals, leading to uncontrollable acceleration or power failure. Get the right lower pedal for modified HOWO control systems instead.

Q2: Acceleration unresponsive or jerky after install?

A2: First check sensor connector (fully plugged in, no looseness). If good, check pedal installation (no stroke obstruction). If installed properly, clear ECU fault codes and test. Still faulty? Replace the pedal (rare defect).

Q3: How to maintain the right lower pedal?

A3: 1. Clean pedal pad often to remove dust/oil (avoid corrosive cleaners); 2. Check sensor connector for looseness/oxidation every 25k km (wipe with dry cloth if oxidized); 3. Avoid excessive force or impact on the pedal to prevent deformation/damage.

Q4: Need to replace wiring harness with new right lower pedal?

A4: Not mandatory but recommended. New pedal works best with intact wiring harness-old ones affect signal stability. Inspect harness and replace if cracked/oxidized for optimal performance.
