Air‑Fuel Ratio Sensor for Toyota Engines ?
Keep your Toyota running clean and strong. This wideband AFR sensor reads the exact oxygen level in exhaust, letting the ECU control fuel with high precision. Result: smooth idle, quick starts, lower fuel use, and long catalyst life. Built to OEM spec, tight threads, fast heater warm‑up, stable signal even in cold or dusty climates.
Why this part is needed ⛽
Modern engines need closed‑loop control to hit the 14.7:1 mix. Without a healthy sensor, the ECU can’t trim fuel correctly, hurting power and emissions.
How it works ?
A zirconia wideband cell and integrated heater create a tiny pump current that mirrors oxygen content. The control unit reads that current and adjusts injectors in milliseconds, keeping the mixture right for every load and temperature.
If it fails ⚠️
Hard start, rough idle, high fuel use, sulfur smell, black soot, poor throttle response, failed inspection, and a lit MIL. Over time the cat can overheat or clog. Common causes: age, leaded fuel, silicone fumes, coolant/oil contamination.
Fitment tips ✅
Install on the upstream position, use anti‑seize on threads (sensor‑safe), torque to spec, and do a reset of fuel trims after install.
