Smile Power Steering Pressure Switch Replacement Guide: 2000 Ford Taurus Duratec 24V DOHC

Symptoms and Diagnosis
A post in a 2004 model thread shows several photos of the spray pattern where the power steering fluid leaked out. The Taurus had been leaking fluid at a slow rate for a while and needed topping off, until a puddle started forming and one day the engine idle bucked the car like a carnival ride between 700 to 1400 rpm until it warmed up and presumably the o-ring and switch membrane partially sealed. I found the spray pattern after that and immediately replaced the switch.


The engine revs up to increase power steering pressure when the pressure is lowered during turning, or will get confused when there is a massive leak such as this. You might not think steering would be related to engine performance, but the drive belt powers the power steering pump.


Replacement of Power Steering Pressure Switch
First buy the replacement. I got one at O'Reilly for about $25. Make sure the o-ring is included! I bought one at Autozone and had to return it as the o-ring was missing. (Photos 1 and 2)


Remove the airbox accordion hose, EGR, throttle body, and upper intake manifold. This FordTechMakuloco video is pretty good, though I also remove the throttle cable and cruise control cable so I can completely remove the throttle body and UIM out of the engine bay.



Clean the area of all the sprayed fluid using appropriate cleaner. I mostly used electrical connector cleaner and paper towels.



If you see fluid pooled in the connector once you remove the 2-wire cable, you're probably on the right track. (Photos 3 and 4)


I used the electrical connector cleaner to thoroughly clean the plug. The blue gasket on the back had been blown off so I cleaned the inside of the connector too and dried it before replacing the gasket. (Photos 5 and 6)


A 9/16" wrench that is 8.5" long will barely fit and give good leverage. Use it to loosen the old switch, then you can easily unscrew it by hand. Quickly put in the new one as fluid will start leaking out. Tighten it with the wrench. You will need to make use of the trick of flipping the wrench over to get 1/12th turns due to the 15 degree offset of the wrench head. It is a tight space to work in. I also suggest buying a new wrench or at least test fitting your wrench with the replacement before starting. My toolkit's 9/16" wrench was a bit short and the head was forged too tight and did not want to slip onto the switch's bolt head. (Photo 7)


Top off the power steering fluid using the owner's manual instructions.



That's it, there should be no more leaks and your engine and steering should run well.

Using a crowfoot wrench would have made the install much easier.

Nice write up OP!


Replacing mine now, it blew :-(, leaking all over the cat, nice and smoky :-(


I found you just need to remove the air filter box cover/hose to TB and transmission dip stick. Use a 15MM stubby, then VOILA removed. I did this before when replacing the Pressure line leaking at the pump. I thought it was leaking at the rack but nope, it was the bloody switch PSS4.

Success!


The old switch was soaked. I picked up a PSS4T from CLARKS DISCOUNT AUTOPART $17 with o-ring :-)


Now the dreaded P0446 Vent Circuit Malfunction, oh the joy.

Cool, glad it helped. Though Jeff K points out that using a crowfoot would be best, that way you can get the proper torque spec. I was wondering how that was supposed to work and didn't know about crowfoot wrenches. Just be sure to either apply the crowfoot to the torque wrench at a right angle or adjust the torque setting for the angle.

I had to replace my leaky sensor too in my 2001 Duratec. I have taken out only the transmission dip-stick, air box cover and the accordion tube and the sensor was visible. Kind of... see the pic below.

I used a 15mm crowfoot wrench with a looong extension to loosen the old sensor. Crowfoot set is $9.99 at Harbor Freight. The extension got the clicker wrench above the cowl, see the pic below for my "construction". After breaking loose the sensor, it will rotate by hand.

The BWD PS104 sensor from AAP was $20.66 ordered online (with a 25% off code from Retailmenot) and picked up locally. I have added one layer of plumber's Teflon tape on the sensor threads and tighten it with the crowfoot. Torqued at "goodandtight" value...
