Throttle Body 55581662 0280750498 S20191 55565489 For Opel

1. Product Performance Features

• Advanced Electronic Throttle Technology: Utilizes "drive-by-wire" technology, precisely controlled by the Engine Control Module (ECM) via an electric motor for rapid and accurate throttle valve positioning.

• High-Precision Components: Features a high-quality DC motor, precision gear set, and durable potentiometer-based position sensors, ensuring signal accuracy and long service life.

• Integrated Design: Combines the motor, throttle plate, sensors, and housing into a compact, highly reliable unit.

• Rugged Environment Suitability: Engineered to withstand under-hood conditions such as high temperature, vibration, and contaminants, with excellent sealing properties.

2. Vehicle Compatibility Table (Core Application Range)

    This throttle body is widely compatible with multiple gasoline models under the Opel/GM umbrella from the late 2000s to mid-2010s, primarily matching engines like 1.6L, 1.8L, 2.0L, and 2.2L.

Critical Note: The above lists common applications. Always perform a final verification using the VIN (Vehicle Identification Number), as this is the only reliable method to confirm part fitment due to model year and specification variations.

3. Purpose

• Core Function: Precisely regulates the volume of fresh air entering the engine's combustion chambers based on driver input (accelerator pedal) and ECM calculations. It is a key actuator controlling engine power output.

• Service Application: Used to replace a faulty original throttle body suffering from internal motor failure, gear wear, sensor malfunction, or carbon buildup causing sticking.

• Symptoms Resolved: Replacement can fix issues such as illuminated check engine light, unstable or high idle, poor acceleration, hesitation, hard starting, or even the engine entering "limp-home" mode.

4. Advantages

• Original Equipment Performance: This is the "OE-equivalent" part, identical to the component installed at the factory, restoring 100% of the vehicle's intended throttle response, fuel economy, and emission levels.

• Perfect Compatibility: Developed specifically for the target vehicles, ensuring a perfect match for both physical installation and electronic communication protocols, with no complex modifications needed.

• Long Service Life: Manufactured with high-quality materials and precision engineering for extended durability, reducing the risk of premature repeat failure.

• Cost-Effective Choice: Often provides better value compared to purchasing a "genuine part" with the carmaker's logo from a dealership, while maintaining identical quality.

5. Service Aspects

• Professional Installation Required: After replacement, a "throttle body adaptation/relearning" procedure MUST be performed using a professional diagnostic scanner to allow the ECM to learn the new component's position baseline. This service is typically provided by qualified repair shops.

• Ready-to-Fit: The part is supplied as a complete assembly, requiring no additional assembly or adjustment, making it a true "plug-and-play" item (after software adaptation).

• Warranty Support:  parts from authorized channels usually come with a quality warranty ranging from 12 to 24 months, providing customer assurance.

• Abundant Technical Resources: As a common service part, its installation and adaptation procedures are widely documented in professional repair platforms and well-known among technicians, making technical support readily available.
