[Shotimes] oxygen sensor

Mon, 24 Apr 2006 16:53:36 -0400

Bosch sensors for the SHO all have the same part number because they use
a generic length of wire coming off of them, and the part number you get
is more than likely enough for both sides. Go to any AAP and I can
guarantee that the part numbers in their database are correct for the 95
ATX. Different part numbers for the most part only mean different
lengths of wire; O2 sensors themselves are all the same (in the 'heated'
category, which ours are in, they're a 2-wire plug). There are 2 of them
in the car, one for each bank of cylinders. The front one is easy to
find, just trace the exhaust pipe up around the tranny and there it is!
It's a bitch to get off unless you have a crow's foot wrench (just ask
for an O2 sensor wrench). The rear one is harder, it's on the other side
of the tranny and waay up there. If you take the plastic half-box thing
off the firewall on the top end you can reach it from above. FYI, 1-wire
= unheated (old type), 2-wire = heated (ours & most others), 4-wire =
Wide Band (expensive).

If you have any more questions, just email back and I (and others) would
be more than happy to enlighten you :).

p.s. [gen1/2]SHOs don't have pre-cat sensors, just two post-cats. I
would recommend the Boschs. They seem to last longer.

Subject: [Shotimes] oxygen sensor

I need to replace the post-cat O2 sensor on my '95 ATX.  I'm a little
confused as to which sensor to purchase.  If I were to buy the OEM
sensor, the front and rear sensors have two different part numbers.
However, if I were to buy the Bosch sensor, the front and rear sensors
appear to be the same part number.  Looking at the descriptions for the
Bosch sensors on various parts websites, it always says "2 sensors
required."  Can someone confirm that the part numbers for the Bosch
sensors are the same for both front and rear locations?  Thanks for the
help!
