The wife's 04 EX-RES started revving from 800 to 1100 RPM rhythmically. Thanks to this site I found the thread about the power steering wire, I looked at mine and it does look like the wire is broken, it's the black wire and looks to be broken right at the connector.

My question is how are the wires secured to the connector? Mine broke so close to the connector that I know a small piece of wire is going to be left behind in the connector. Are there some sort of pins holding the wire? It would be a much easier fix if I had some more length before the break.

Thanks guys

You need to disassemble the connector. Cut the wire, take the connector to your desk, and try all kinds of tools you have to take it apart. Once the connector is opened up, it is easy to solder a piece of wire to it. I did this to my 02 a few years ago, and it took me about 2 hours.

Can you buy a new connector with wires already attached to it and splice that onto the van? I tried to look around to find the part but can't seem to find it, I may be calling it the wrong thing, I've been searching for "power steering wire harness"

You might be able to get 1 at a salvage yard for a couple bucks. Then you could take yours apart and repair it for a backup.

Power steering switch connector is on the right engine compartment wiring harness. You might be able to find the connector by googling automotive connectors and matching up by looks.

Which part of it comes out? There's the gray housing and a white sleeve that slides in there. How did you get it apart without breaking it?

It's easy to pull it under the car but you need to raise the car at the same time to have some room. You also need to unplug the connector for O2 sensor . I drill into the pigtail using 1/16 to pull out the pin and solder a wire then put it back again. It works. I look everywhere and nobody is selling it ( dealer wants me to but the whole wiring harness for $ 200.00). Did mine two days ago.

Thanks for the responses. I got it fixed last night. I disconnected the connector and then traced the green and black wires up the wire conduit to a point higher up in the engine compartment. Then, I pulled the green and black wires out of the wire conduit, after pulling the sticky black electrical tape off of them. Having twelve inches or so to work with, I cut a few inches of the corroded wire off and set to work on rehabbing the connector. There's a green rubbery plug on the end of the connector you can pull out to get to the internals. Then, you need to remove the white spacer -- I used dental tools. After that I took the metal contacts out to solder on some new wires. Reassemble everything, use some wire crimp connectors to add six inches or so of new wire and connect everything back up. I sealed the crimp connectors with black RTV to keep water out of the connectors. I was surprised at how corroded the wires were, even far from the sensor. Guess ten years has been hard on electrical components.

I definitely have the broken wire. Noticed it was broken about two years ago when replacing cv's. With it broken I haven't noticed anything different about the way the van runs or drives. What are the symptoms for this wire being broken on an 02 EX? Should I bother with it if no symptoms are present?

If you don't notice any symptoms, don't worry about it. My idle was slowly hunting up and down by a few hundred rpms while in neutral. I don't even think my wife noticed it. It bugged me so I tracked it down. ;)
