Gen III downstream O2 sensor

[Worshington]

Is it just me or is the wiring harness for this the ultimate PITA? Been under the truck for an hour and haven't even been able to disconnect the damn thing. Anyone got a trick for this?

Thin tip mini flathead to pry with a bit once you depress the clip lever. It's the same type of connector used topside under the hood so look at that one for reference.

Thanks Salonika, I just went and washed the undercarriage, a lot of mud caked under there, I'm gonna give it another shot as soon as it cools down.

All taken care of. Just needed to try a different angle and it slid right off. Now we'll have to see if that pesky service light stays off.

If it's the p0421 you might need a new cat. Or cheat the sensor like this: http://www.civicforums.com/forums/2...lug-non-fouler-trick-installation-w-pics.html
