MD628227 Mitsubishi SENSOR,THROT BODY THROTTLE, Price: 145.06$, Weight: 0.03kg

Throttle Position Sensor for Mitsubishi (MD628227)

Why you need it

This throttle body sensor feeds the ECU with exact pedal and butterfly angle. With correct TPS data you get smooth idle, sharp acceleration, cleaner emissions, stable ignition timing, and proper automatic shift timing. It keeps fuel delivery precise, saving gas and protecting the engine. ⚙️

How it works

Mounted on the throttle shaft, the TPS uses a calibrated potentiometer and an idle switch to turn movement into a 0.5–4.5 V signal. The ECU tracks this voltage curve to meter fuel, control purge/EGR, and manage torque. Designed to match OEM spec MD628227, it delivers a steady closed‑throttle reading and linear output across the full sweep for predictable response.

What happens if it’s broken

Symptoms include hard starts, high or hunting idle, tip‑in hesitation, flat spots, stalls after decel, poor MPG, and erratic shifting. The Check Engine light may show P0120–P0123 or P0220‑range codes. Wear on the resistive track causes dead spots; moisture ingress or a loose rotor adds signal dropouts. Ignoring it can trigger limp mode, rich running, and catalytic converter stress. Replace to restore clean, consistent driveability. ✅
