Wideband AFR Sensor for Precise Mixture Control

This advanced wideband O2 unit keeps your Toyota engine breathing right. It sends fast, accurate feedback to the ECU, so fuel and air stay in perfect balance. Result: smooth idle, clean emissions, strong throttle, and better fuel economy .

Why you need it

The sensor maintains the ideal 14.7:1 mixture in closed loop. It protects the catalytic converter, reduces fuel waste, and helps your vehicle pass inspection. A healthy sensor saves money at the pump and extends exhaust system life.

How it works

Mounted upstream of the catalyst, the wideband element uses a pump cell and heater to measure oxygen in the exhaust. It outputs a current the ECU reads in milliseconds, then trims injector pulse to keep the mixture spot on under idle, cruise, and load βš™οΈ.

What happens if it’s broken

Expect hard starts, rough idle, hesitation, higher fuel use, sulfur smell, and black soot. The Check Engine light may appear with mixture codes (e.g., P2195/P2197). Running rich can overheat and damage the catalytic converter .

Tech tips

Fix vacuum or exhaust leaks first, use proper anti-seize on threads only, avoid silicone sprays, and perform a learn/adaptation reset after installation ✨.
