Intake Air Meter Sub‑Assembly for Toyota Engines ✅

This OEM-grade intake air flow sensor (MAF) measures how much air enters the engine, letting the ECU set the right fuel dose. Precise airflow data means smooth starts, strong pull, clean exhaust, and better mpg. Built for Toyota platforms, it fits the air duct just after the filter and before the throttle, using a sealed housing for stable readings.

Why Your Engine Needs It

Without accurate air data, the mixture goes rich or lean. Correct fuel mapping protects the catalytic converter, keeps idle steady, and preserves power on hills and highway merges.

How It Works ⚙️

Inside is a heated element and intake temperature sensor. As air passes, it cools the element; the circuit adds current to hold target heat. That current change equals airflow. The ECU converts this signal into fuel injector timing for precise air‑fuel ratio.

When It Fails — Signs and Risks ❗

• Rough idle, hesitation, or flat spots on acceleration
• Poor fuel economy and black tailpipe soot
• Check Engine Light with lean/rich or airflow codes
• Hard starts, stalling, premature catalytic damage

Tech Tips

Inspect the air filter and ducting; no leaks before the sensor. Do not touch the hot film; clean only with MAF spray. Ensure proper orientation and a tight seal. After install, clear codes and allow a short relearn drive cycle.
