RENAULT KWID BR10 THROTTLE BODY UNIT

The Renault Kwid electronic throttle body regulates the amount of air entering the 1.0L 3-cylinder engine when you press the accelerator pedal. Function & Location What it does: Controls engine airflow to manage acceleration, idling, and overall fuel efficiency. Where it sits: Mounted directly on the engine between the air filter box and the intake manifold. Common failure signs: Rough idling, loss of power, engine hesitation, or unexpected stalling. Mechanism of Action Signal processing: Pressing the accelerator pedal sends a voltage signal to the ECU. Valve actuation: The ECU commands an internal electric motor inside the throttle body to open or close a butterfly valve (plate). Air-fuel adjustment: A built-in Throttle Position Sensor (TPS) tracks the exact angle of the valve and reports back to the ECU, which then meters the correct amount of fuel injection. Specifications Operating Voltage: 12 volts [1] Connector/Pin Count: 6-pin electrical connector [1, 2, 3] Bore Diameter: Varies slightly by aftermarket/OEM specification, typically around 41mm to 60mm depending on the exact manufacturing batch and engine type (0.8L vs 1.0L). [1, 2, 3] Control Note: Replacement or deep cleaning often requires an idle relearn procedure or software update via an OBD scanner to match factory ECU specifications
