What’s the difference between upstream and downstream o2 sensors?
The upstream oxygen sensor is situated before the catalytic converter whereas the downstream oxygen sensor is located after the catalytic converter. The upstream sensor monitors the level of pollutants in the engine’s exhaust and sends this information to the ECU that continuously adjusts the air-fuel ratio.
How do you reset the check engine light after changing o2 sensor?
Turn the ignition to the “On” position but don’t crank the engine (it won’t start anyway). Wait five minutes and reinsert the fuse. The “Check Engine” light will blink, then shut off.
