Air Intake Flow Sensor Assembly for Toyota 🚗

This unit measures the air your engine breathes and sends the data to the ECU. With the right numbers, the computer sets fuel, ignition, and idle perfectly. Result: smooth power, clean emissions, and good fuel economy.

Why this part is needed ✅

Modern Toyota engines rely on precise air readings to balance the fuel mixture. A healthy air flow sensor keeps starts quick, throttle response sharp, and catalytic converter protected. It is vital for daily reliability and inspection readiness.

How it works ⚙️

Inside is a heated element (hot-wire/hot-film). As air passes, it cools the element. The circuit adds current to keep temperature stable. That current equals air mass. The ECU uses this signal to control injectors and timing in real time.

What happens if it’s bad ⚠️

Expect rough idle, hard starts, hesitation, high fuel use, black smoke, or lack of power. Check engine light may show MAF codes. Running rich can foul plugs and harm the catalyst; running lean can overheat valves.

Fitment, install, and care 🛠️

OEM-style plug-and-play. Mount with arrow toward engine, after the air filter. Inspect hoses for leaks. Do not touch the sensing film; clean only with MAF-safe spray. After install, clear codes and let the engine idle 5–10 minutes to relearn. Enjoy restored performance and economy. 👍
