the manual for the 93 trooper (dohc, 3.2 liter) mentions there is an attachment (pipe, wire, line) connected permanently to the O2 sensor (the manual calls it the HO2S) and warns against disconnecting or changing the connection
does that mean that only the original isuzu part will work as opposed to a Denso/Bosch replacement O2 sensor? or do the replacement sensors also come with the needed attachment(s) ?
anyone done this replacement - did it require special adapter or special tool(s) ?
sorry I don't know the answer but I have this job scheduled next week and will post back the reply from one of the mechanics unless someone else let's you know the answer first
I know I'm way late tagging my reply here...but for future reference, the 93 (at least with SOHC) just trips the O2 light at 90k miles. There's a screw you can move in the back of the dash to get it to turn off...simply replacing the O2 sensor won't turn it off. See
