MD614488 Mitsubishi SENSOR,THROT BODY THROTTLE, Price: 233.71$, Weight: 0.06kg

Throttle Body Position Sensor

✅ This sensor is a key part of the throttle body system. It tells the ECU the exact angle of the throttle plate, so the engine can deliver the right fuel and ignition timing. Without a correct signal, the car cannot “understand” your accelerator input, especially during take-off, cruising, and sudden acceleration.

Why this part is needed

⚙️ Modern engines rely on accurate throttle position data to keep idle stable, prevent hesitation, and control automatic transmission shift behavior. When you press the pedal, this sensor converts throttle movement into an electrical voltage signal the ECU can read in real time.

How it works

? Inside is a precision potentiometer (or contact track) linked to the throttle shaft. As the throttle opens or closes, the sensor output changes smoothly. The ECU compares this signal with airflow and RPM data, then adjusts injector pulse and timing to keep performance clean and efficient.

What happens if it’s broken

⚠️ A failing sensor may cause rough idle, delayed throttle response, surging, poor fuel economy, stalling at stops, or limp mode. You may also see a check engine light and inconsistent shifting because the ECU loses reliable throttle angle feedback.
