SDEC Electronic Accelerator Pedal D88A-007-800+D – OEM Replacement 860121897

SDEC Engine Electronic Accelerator Pedal D88A-007-800+D – Direct 

Product Overview
This Electronic Accelerator Pedal (model D88A-007-800+D) is a high-precision, wear-resistant component engineered specifically for SDEC (Shanghai Diesel Engine) series power systems. Serving as a direct replacement for OEM part numbers 860121897 and S00006195+01, this pedal converts mechanical motion into electronic signals to ensure real-time communication with the Engine Control Unit (ECU). It is widely used in commercial trucks, construction machinery, and bus fleets that require reliable throttle response under heavy-duty conditions.

Key Technical Specifications

Product Name: Electronic Accelerator Pedal / Drive-by-Wire Throttle Pedal

Mounting Hole Spacing: Standard 44mm x 44mm (compatible with most SDEC cabin pedal brackets)

Safety & Protection Features

1. Idle Validation Switch (IVS)
The pedal incorporates a built-in idle validation switch that confirms the closed-throttle position. This prevents unintended acceleration when the pedal is released and ensures the engine returns to idle speed reliably.

2. Limp-Home Mode
In the event of sensor signal loss or unrealistic voltage readings, the ECU automatically activates engine protection mode (reduced power and speed limitation). This safety mechanism alerts the driver to a potential fault while allowing the vehicle to be driven slowly to a service location, avoiding dangerous sudden power loss.

3. Vibration & Corrosion Resistance
Tested under extreme vibration frequencies (10Hz to 500Hz) and salt-spray environments, this pedal maintains stable output signals, making it suitable for off-road construction equipment and long-haul trucks operating in harsh weather conditions.

Compatibility & Vehicle Applications
This D88A-007-800+D pedal is primarily designed for SDEC engines, but it also offers cross-compatibility with several heavy-duty vehicle brands that use the same electronic control architecture. It is commonly found in:

• SDEC-powered Dongfeng, Shacman, and Sinotruk HOWO trucks

• Foton Daimler commercial vehicles with SDEC engine options

• Bus and coach models equipped with SDEC D-series power units

• Construction equipment (excavators, wheel loaders, and cranes) using SDEC industrial engines

For a complete list of verified fitment, please check your existing pedal mounting bracket pattern and compare it with the 44mm x 44mm standard dimension.

Why Choose This D88A-007-800+D Pedal?

• OEM-grade quality: Manufactured to meet or exceed original SDEC specifications, ensuring plug-and-play installation without modification.

• Stringent testing: 100% factory-tested for output voltage linearity, idle validation, and thermal cycling before shipment.

• Cost-effective alternative: Provides the same durability and performance as genuine OEM parts at a competitive price point.

• Global compatibility: Engineered to suit both Euro II and Euro III emission standard SDEC engines commonly found in export markets.
