Can I use wd40 to remove O2 sensor?

As your vehicle’s oxygen sensors are seldom removed, they will probably be firmly stuck in place. To loosen them, spray the sensors with a lubricant like WD-40 and let them sit for 10–15 minutes. The WD-40 will lubricate and loosen the sensors, making them easier to remove.

There are no true oxygen sensor cleaners that are safe to put through your engine. While some people choose to remove them and use a wire brush or an aerosol cleaner to remove deposits, we do not recommend trying to clean O2 sensors.

Can I use carb cleaner to clean O2 sensor?

Don’t do it. If they only have 400 miles on them and you haven’t contaminated them with coolant in the exhaust or silicone from things like certain kinds of RTV on the intake gaskets or done something to them after taking them off the car, then they’re probably fine. Soot on the sensor tip is normal.
