Hi everyone,

I am hoping I can get some other gear heads to help me out here. I have a 2000 4.7 Durango. Recently my Power Steering Pressure Switch went bad and as many of you know it shot Fluid into my harness and eventually it reached my o2 sensor. That caused my mileage to drop and exhaust to stink.

So after much research I decided I would just reroute most of the cables and run new ones to the PCM. I picked up the universal Bosch o2 Sensor for the upstream and a Bosch OEM for the back.

The Upstream sensor consists of 4 wires: (18 gauge)
================================================== ======
1. OR/DG - Fused Auto Shut Down Relay Output - Cut this from original contaminated harness and connected to "white wire" on bosch o2. (Bosch calls it a heated wire)

2. BK - Ground ==> Ran new wire to harness 1 by PCM and connected using crimp style onto BK/TN (Ground). From looking at the diagrams this is the source of the contamination!

3. BK/LB - Sensor Ground (This is the PCM ground) ==> Ran new wire to harness 1 by PCM and connected to BK/LB at PCM (Sensor Ground).

4. LG/RD - Oxygen Sensor 1/1 Signal ==> Ran new wire to harness 1 by PCM connected to LG/RD wire using a butt connector (I didn't solder because I read something about oxygen and the sensor needing it)

I actually was documenting the whole process so everyone out there could fix it themselves. But as opf right now my tutorial is a failure.

After putting everything back and taking a ride I got an engine light on. Code "p0132" aka "O2 Sensor Shorted To Voltage Oxygen sensor input voltage".

I can't for the life of me figure out why this code has popped up. I took a short trip and once I started to get home the truck felt like it was about to stall. I put my foot on the gas and it was just totally about to shut off.

Suggestions would greatly be appreciated. :frown:
