Nissens 955089 Electric Throttle Body with Integrated Position Sensor

The Nissens 955089 is a complete, factory-new electric throttle body engineered as a premium-quality aftermarket replacement for OE-equivalent performance. Designed to regulate airflow into the engine, the throttle body sits between the air filter box and the intake manifold, controlling the volume of air reaching the combustion chamber by opening and closing an internal throttle plate.

When the accelerator is pressed, the throttle plate rotates to admit air; working in concert with the ECU and mass airflow (MAF) sensor, the unit enables precise fuel injection adjustments for an optimal air-to-fuel ratio, directly impacting engine performance, fuel efficiency, and emissions control.

Key Features:

• Electric actuator — electronically controlled throttle plate for precise, drive-by-wire operation
• Integrated throttle position sensor — built-in sensor for accurate real-time feedback to the ECU
• No vacuum bypass — designed for applications that do not require a vacuum bypass port
• No gaskets/seals included — unit ships without gaskets; source application-appropriate seals separately
• Complete factory-new unit — not remanufactured; no core charge, no core return required
• Nissens quality tested — subjected to functional, high-temperature endurance, durability, load, and corrosion testing
• OE-matching fit and performance — manufactured to original equipment standards for a direct, first-time-right installation

Important Installation Note: After installation, the engine control unit (ECU) software must be trained or updated (throttle body adaptation/relearn procedure required). This procedure should be performed by a qualified technician using manufacturer-specific diagnostic equipment and repair instructions.

The Nissens 955089 throttle body delivers reliable, long-lasting engine airflow management as a trusted alternative to the OE part, backed by Nissens' decades of engineering expertise in engine efficiency and emissions system components.
