LQ1 O2 sensor replacement?

« on: May 12, 2010, 11:39:17 AM »

What's the easiest way to get to that bastard? I hear its behind the engine, and I'm going to be pulling off both front wheels, can I get to it from a wheelwell or what?

Oh, car is 91 and engine is 93. Believe it or not there are some differences between the two years of engines (not much tho)

o2 sensor socket may be your friend, or you may need a 7/8 Wrench, wichever you have room, all you gotta do it break it loose, it will spin out by hand at that point so you dont need much room

if you pull struts and knuckles, yes, you should be able to get to it without rocking the motor.

EDIT: alldata says the easiest way is to get it from underneath...
