Electronic accelerator pedal is the primary driver input device for engine throttle control on the HOWO MAX 4X2 tractor. A reliable electronic accelerator pedal ensures precise engine response, smooth acceleration, and optimal fuel efficiency. This genuine HOWO electronic accelerator pedal kit includes the complete pedal assembly and all required mounting hardware.
When you choose authentic Howo Parts, you receive an electronic accelerator pedal engineered to meet the exact specifications of the HOWO MAX 4X2 cab floor mounting points.
The electronic accelerator assembly is the complete pedal unit that houses the position sensor, pedal lever, and return spring mechanism. This assembly is manufactured from glass reinforced nylon for high strength and wear resistance. The electronic accelerator assembly contains a dual channel non contact Hall effect sensor that converts pedal angle into a voltage signal for the engine control unit.
The sensor output is redundant and self checking, ensuring safe operation even in the event of a single channel failure. The pedal lever features a textured rubber surface for secure foot grip, even when wet. The return spring mechanism provides progressive resistance that matches driver expectations,
with a defined hysteresis curve that reduces driver fatigue during long hauls. The pivot points are fitted with stainless steel bushings for long term durability. The electronic accelerator assembly is sealed to IP67 standard, making it resistant to dust and water ingress from floor washing or rain entry. The assembly is pre calibrated to the HOWO engine control unit and requires no additional programming after installation.
The hexagon bolt with flange M10 is used to secure the electronic accelerator pedal to the cab floor. Two bolts are supplied, each with an integrated flange that distributes clamping pressure evenly across the pedal mounting bracket. The bolts are made from grade 10.9 steel with a zinc flake coating that resists corrosion.
The flange has a serrated underside that bites into the floor panel to prevent loosening under vibration. The bolts have a thread length of 20mm and a hex head size of 15mm across flats. They are torqued to 25 Nm during installation, providing a secure clamp that will not loosen over time. These hexagon bolts are specially designed for the electronic accelerator pedal mounting pattern and should not be substituted with standard hardware.

The electronic accelerator pedal uses a dual channel, non contact Hall effect sensor that provides accurate throttle position feedback to the engine ECU. This technology is more reliable than potentiometer based pedals, as there are no wiper contacts to wear out. The sensor output is linear and repeatable across the full pedal travel range.
This electronic accelerator pedal features two independent sensor channels that monitor each other. If a discrepancy is detected, the system defaults to idle and illuminates a warning light. This fail safe design prevents unintended acceleration and meets ISO 26262 functional safety requirements for commercial vehicles.
The electronic accelerator pedal connects directly to the factory wiring harness using a sealed 6 pin connector. No programming or calibration is required after installation, as the sensor is pre matched to the HOWO engine control unit. The included hexagon bolts simplify mounting to the existing floor holes.
The pedal lever is shaped to follow natural foot movement, reducing ankle fatigue during long driving shifts. The textured rubber surface provides excellent grip, and the progressive spring resistance gives the driver a confident feel for throttle modulation. The pedal width and height are optimized for the HOWO cab floor geometry.
The electronic accelerator pedal converts the driver’s foot position into an electrical signal that the engine control unit uses to determine fuel delivery. Unlike traditional cable operated throttles, this system has no moving cables that can stretch or bind. When the driver presses the pedal, the Hall effect sensor detects the angular position of the pedal lever and sends a corresponding voltage to the ECU.
The ECU then commands the fuel injection system to deliver the appropriate amount of fuel. This electronic accelerator pedal provides faster response times and allows for integrated features such as cruise control, engine braking, and idle validation. The sensor output is refreshed multiple times per second, ensuring smooth and precise throttle control even during rapid pedal movements.
The electronic accelerator pedal assembly is built to withstand the harsh environment of a truck cab. The housing is molded from impact resistant polyamide with glass fiber reinforcement. The pedal lever is made from the same material with additional ribbing for stiffness. The pivot points use self lubricating bronze bushings that require no maintenance.
The return springs are made from music wire with a corrosion resistant coating. The electrical connector is a Deutsch style sealed unit that resists moisture and vibration. The circuit board inside the assembly is conformally coated to protect against humidity and condensation. Every electronic accelerator pedal is tested on a custom fixture that verifies sensor linearity, return spring force, and connector pin retention before leaving the factory.
Before starting, disconnect the battery ground cable. Remove the driver side floor trim panel to access the mounting area. Remove the old pedal assembly by unscrewing the two mounting bolts and disconnecting the electrical connector. Clean the floor mounting surface to remove any dirt or debris.
Position the new electronic accelerator pedal over the mounting holes, ensuring the electrical connector is oriented correctly. Install the two hexagon bolts with flange M10 and torque them to 25 Nm. Do not overtighten, as this could crack the plastic housing. Connect the electrical harness to the pedal,
pushing firmly until the connector clicks. Reconnect the battery ground cable. Start the engine and test the pedal operation. The engine should respond immediately to any pedal movement, and the idle speed should return to normal when the pedal is released. No additional programming is required, as the electronic accelerator pedal is pre calibrated at the factory.
This electronic accelerator pedal is designed for all HOWO MAX 4X2 tractors equipped with electronic engine management systems. It is compatible with both manual and automatic transmission versions. The pedal fits the standard cab and sleeper cab floor layouts without modification. It also fits HOWO MAX 6X4 and 8X4 variants that use the same cab floor stamping.
For older HOWO 70 series trucks, check the connector type before ordering, as some early models used a different pedal design. The hexagon bolts with flange M10 are a standard size and can be reused from the original pedal if necessary, but new bolts are supplied in the kit for convenience.
Common symptoms of a failing electronic accelerator pedal include erratic engine response, hesitation during acceleration, or the engine failing to return to idle when the pedal is released. In some cases, the engine control unit may log a fault code related to throttle position sensor rationality. If the pedal internal sensor fails completely, the engine will default to idle and may not respond to pedal input at all,
a safety feature of the electronic accelerator pedal system. Drivers may also notice a change in pedal effort, either becoming too stiff or too loose, indicating a worn return spring. Any of these symptoms should be addressed immediately, as a malfunctioning electronic accelerator pedal can make the vehicle difficult or dangerous to drive. Replacement is straightforward using this genuine pedal kit.
The electronic accelerator pedal requires very little routine maintenance. However, it is a good practice to inspect the pedal assembly during regular cab interior cleaning. Check for any debris that may have accumulated around the pivot point, which could interfere with smooth operation. Verify that the two hexagon bolts remain tight; if they have loosened, retorque them to 25 Nm.
Inspect the electrical connector for signs of corrosion or damage. If the pedal feels sticky, it may need cleaning. Do not use oil or grease on the pivot point, as this can attract dirt. Instead, use a dry lubricant spray designed for plastic components. The electronic accelerator pedal has no user serviceable parts inside; if the sensor or electronics fail, the entire assembly must be replaced with a genuine unit.
Aftermarket electronic accelerator pedals often use lower quality potentiometers that wear out quickly, leading to erratic throttle response. The Hall effect sensor in the genuine HOWO pedal has no physical contact and will last for millions of cycles. Aftermarket pedals may have incorrect spring rates, making the pedal feel too heavy or too light.
The genuine pedal is tuned to the exact force profile specified by HOWO engineers. The mounting bolt pattern on aftermarket pedals may not align correctly, requiring modifications to the cab floor. The genuine electronic accelerator pedal matches the factory holes precisely.
The connector may also differ, forcing technicians to cut and splice wires. The genuine pedal uses the identical connector as the original, so installation is completely plug and play. For fleet operators, using genuine electronic accelerator pedals reduces downtime and ensures consistent driver feel across all vehicles.
The electronic accelerator pedal is manufactured in an ISO 14001 certified facility. The plastic housing is made from recyclable polyamide, and the circuit board is lead free. The packaging consists of a cardboard box with molded pulp inserts that hold the pedal securely during shipping.
