Toyota O2 Sensor/Oxygen Sensor

The oxygen sensor is constantly sniffing the exhaust and sending the computer a fluctuating signal where it says in effect “a little more gas” and then “a little less gas.”

If it gets sluggish so that it’s slow to update it’s report, then it might get stuck saying “more, more, more-oops-less, less, less.” A sluggish O2 sensor can cause your idle to hunt where the rpm’s wander up and down a bit.

It can also cause some surging feel when driving at lower speeds with light-throttle acceleration or light-throttle cruise. A properly working O2 sensor is needed for fuel economy, for clean emissions, and your basic engine performance.
