VSS

[escortwgn]

Just removed my stubborn VSS and discovered it was not installed right and that's why my speedo is dead. My question is, my truck is listed as a 90, looking at the part pictures, the part i removed was an 89. The sensor on my truck has a 2 pin connector and the cable. Based on the picture for the 90, it's just a 2 pin. Did they redesign for 90, and/or does it really make a difference?

Thanks

Yo Justin,

Buy one from local Ford dealer. Many issues with aftermarket recently.

Applications, Bronco:

Pre~85 used a cable-mounted VSS (6 pulses per cable rev) for cruise only;

~85-91 used a t-case mounted VSS (6 pulses per cable rev) for cruise and E4OD shifting. The ABS sensor was only used for RABS.

The E4OD ESOF t-case always had its own dedicated speed sensor in the tailhousing;

Miesk5 Note; 92-96 use the ABS sensor (108 pulses per diff rev) in the rear axle (via the ABS module) to feed the PSOM, which then feeds everything else.

Yo Justin,

I forgot about the speedometer.

To release the speedo cable from the cluster, push the large white plastic collar down, then back.

The cable end locks automatically when you push it into the back of the speedo. Look at them while it's apart & you'll unnerstand. by Steve

Chilton; "Reach up behind the cluster and disconnect the cable by depressing the quick disconnect tab and pulling the cable away.

Remove the cable from the casing. If the cable is broken, raise the vehicle on a hoist and disconnect the cable from the transmission.

Remove the cable from the casing.

To remove the casing from the vehicle pull it through the floor pan.

To install:

To replace the cable, slide the new cable into the casing and connect it at the transmission.

Route the cable through the floor pan and position the grommet in its groove in the floor.

Push the cable onto the speedometer head."

Lubrication; This is for a Stang, but similar "...Cable function depends hugely on lubrication and plenty of it. When lubrication becomes lean, cables bind and deteriorate, which only makes the problem worse. If the cable has deteriorated to where it is frayed anywhere along its length, it's time to replace the entire cable assembly. Frayed speedometer cables damage the inside of the sheath to create two sources of binding. This is why entire cable assembly replacement is so important to smooth speedometer operation. Here's the transmission end... Here's the transmission end of a speedometer cable, which takes a #N751 o-ring and the appropriate speedometer drive gear, chosen depending on the transmission and rear axle gear. New cables are already equipped with the o-ring. The barber pole pathway carries transmission lubrication to the drive gear.When you install a new speedometer cable or service an old one, generously lubricate the cable with a mixture of transmission fluid and lightweight lithium grease. Mix up a modest *** of lithium grease and transmission fluid in the palm of your hand and run the cable through it. You can also use speedometer cable lubricant for this purpose. Run the cable back and forth until saturated with ****. Then, slip it into the cable sheath..."
