This is on my '01 Dak (4.7). I called around to see
who had the best price on an upstream 02 sensor,and
Advance said $81.00. So I went after it,and began the
arduous process of changing it.
One word of advice to anyone else who has a 4.7/45RFE
that throws this code,and is anxious to fix it
themselves:
Dear friend,let me tell you something. I don't know
your situation regarding how far you are able to lift
a vehicle,or the tools at your disposal. I can only
speak for myself,having only two plastic ramps,some
Craftsman sockets and basic hand tools. But changing
an upstream 02 sensor on a 4.7 Dak,at least on the
passenger side,is something I found personally
offensive. You can gain access to and remove the
sensor by removing the fenderwell liner and using a
7/8" crowsfoot adaptor. But accessing the cable end
and harness are the true fun! You see,they are wedged
tightly between the transmission and the heat shield
on the body,way the h*ck up in there! Once you pull
the sensor end loose,you can yank some slack in the
harness and disconnect the plug,but it's a nightmare.
Then you have to cut the plug off the cable,because
there's no room to pull either end through to get it
off the truck! I tried for twenty minutes,and if
you'll pardon the expression,"That stuff just wasn't
happening". :)
Anyway,the sensor ended up being wrong. Advance's "OE
Type" sensor had the wrong plug. So I got a Bosch
universal type instead and went through all
that,getting the wires cross-referenced and connected.
But the good news is,my code is gone,and the Elmscan
shows comparable fuel trim on both sides,similar
voltages on both sides.
Now all I need to do is clean the soot off my trumpets
and I'm all but good to go! :)
