I've recently purchased a 1996 Ford F150 4X4 single cab short box with 160,000 KM on 302 V8 motor. Everything seems to be in good order except check engine light is on and indicates O2 sensor problem...I believe there are 3 sensors....should I replace all three as I am sure they haven't been replaced before. Is there any other way to correct this problem?

Put new 31X10.5X15 Goodyear Territories on it, Pics to come soon.

 

Welcome to the site, I would repalce all of them

 

When in doubt, throw em all out. Welcome

 

Is there any way to test them....continuity or?? Pretty nasty environment for those sensors to exist.....just buy them all I guess!! Where is the best place to buy these sensors or any other aftermarket part for these trucks?

 

Welcome to F150forum.com Lots of good guys and gals here...be sure to post some pictures
