What to do if 2, 2 O2 sensor is stuck?
If, after starting the engine and warming to operating temperature, the 2,2 oxygen sensor is observed to be stuck high, or close to 1 volt and the voltage doesn’t drop or vary, then turn the engine off. With KOEO (key on engine off) unplug the 2,2 o2 sensor and check for a good ground on both the heater element and the sensor.
When to reset the ECU after changing an O2 sensor?
Sometimes an O2 sensor fails, and you need to replace it. Once you’ve replaced your vehicle’s O2 sensor, you’ll need to reset the ECU so it can properly gather information from the new O2 sensor.

When does an O2 sensor cause a surge?
Normally, your computer will throw a check-engine light and an O2 sensor failure code when the sensor gets bad enough to surge. But this isn’t always the case; sometimes, the O2 sensor can trick the computer into thinking that everything’s fine. One quick way to diagnose O2 sensor surge is to unplug the O2 sensor’s wiring harness.
What happens if your O2 sensor gets stuck?
If it gets stuck open, too much exhaust gas is mixed with the intake air-fuel mixture. This will drag down your actual O2 level as seen by the wideband O2 sensor/air-fuel sensor that is situated before your upstream catalytic converter.
