Question about 2000 Dodge Durango

1 Answer

I have a 2000 Dodge Durango that had been setting off multiple engine codes. I took to a mechanic today that told me a bad Power Steering Pressure Sensor caused oil to be pulled through the entire engine wiring harness and is currently shorting out all electrical connections and possibly the ECU. He then told me it wasnt worth replacing and to get a new vehicle. What would be the approximate cost to replace the harness and the ECU?

    He showed me postings from his mechanics network thing and they all said it was extremely rare but it has happened before. I followed the harness around all the exposed connections and pulled back the insulation, it is covered in oil inside and outside of the insulated coverings. It runs fine, other than the fact it is burning gas at twice the normal speed, but the mechanic thinks the O2 sensors, which are about 2 months old, are being fried again as well because of this problem. I didnt think he was bs-ing me, since most mechanics I've ever dealt with, would have tried to get me to spend the money to replace the harness and ECU/ECM.

Im not sure about the price. I would go to the junk yard. However, I have never heard of this happening to anybody in my life. I do not see how powersteering fluid would get in the whole wiring harness. The only places that it would or could make a difference is on the plugs. The rest of the harness has wires with insulation on them. If there is oil fouling out the system? Go to Autozone or Advanced, etc. Get some electronic connector cleaner. And or Electric Motor cleaner. It is about $6 a can. Find the power steering sensor. Change it or just unplug it. Spray all in the contacts. Then follow the harness to next plug. See if there is powersteering fluid. Clean every contact you see. Dont be scared it evaporates quickly and is electrical safe. Even find the ECM or ECU whatever it is called. And clean it. Oh Ya. Remove the negative battery cable before you start this.

Then after you clean all of them. Hook the power back up. And remove the ECM fuse in both fuse boxes. Leave them out for 5 minutes. Then plug them back up. That will reset the check engine light. And see what happens then. Make sure power is hooked up before you pull ecm fuses. Or it will not reset.


I hope this helps. If not, take it to someone else. I will give you scrap price for it. LOL

    Well thank you very much for getting back to me on that. I have never heard of that happening. Im not real familiar with Dodge products. Most of the vehicals I work on the wire harness stops and it just has the wires going to the sensors. Then any leaks would just leak. As far as I know. Seems to me like that should be a recall. Or something. LOL.

Having problem with power steering 2000 Dodge Durango. Could it be the power steering pressure switch?


The pressure switch is only there to tell the PCM (computer) when the pump is developing high pressure. If the engine RPM is near idle (as when parking), the PCM will increase idle speed through the inlet air control (IAC) valve to prevent stalling. The pressure switch has nothing to do with the function of the power steering itself.

2000 Dodge Durango bad steering pully cable and pump


Unless the tow truck operator hooked up to the wrong thing the tow will have nothing to do with it.

I have never heard of any connection to the transmission and power steering, so the chances of the transmission repair causing the p/s failure is pretty low.

Is the repair shop reputible? I would recommend a second opinion from another shop.
