Default 98 ranger VSS craziness

98 Ford Ranger 3.0 L, RWD (no transfer case, no housing extention), VSS problem :

The safety compliance sticker on the drivers door says “transmission code = B”. Chiltons repair manual does not even list a code B, nor does any other site I have been to. I am trying to find out what exactly this tranny is, and if there is a VSS inside, or on the tranny, but can not seem to get the same answer from any of the 6 sources I checked with.

The ABS pumps the brakes at normal braking (intermittent), and the speedo drops out (intermittent, seems worse when ambient temps are high. AZ = 100 + about now). I replaced the differential mounted sensor with an AutoZone sensor that looked the same. Still having same symptoms. Old sensor removed read 1200 ohms. OBDII check with new sensor says P1502 VSS SENSOR SYSTEM, indicating a sensor inside or on the tranny ??? According to this code and the VIN #, Ford sent a replacement part that won’t fit anywhere I can find, on the tranny (outside mount) or on the differential, and looks a lot like the differential mounted sensor but not exactly.

Most sites I checked say there is only one VSS on 98 Rangers, and it is on the differential, but I am getting conflicting signals from the OBDII. I bought this truck, used, in 2000 and have had no reason to suspect a tranny switch out from OEM, as nothing has been goofy till 11 years later. What do I really have and what do I need to fix it ?

I have some pics : what is the blue capped device on the tranny, drivers side?

I will remove the new VSS one more time, and be sure it does not “rock” when installed, as that is all I know to do. Does anyone have some other ideas out there ???

You sure that "B" isn't a "D"?

On a 98, the only VSS sensor should be on the axle shaft. However I know that on the 5R55E, there is supposedly no VSS, because speed sensing is done by the Output Shaft Sensor mounted on the tailshaft of the transmission.

it sounds like you have an Automatic Transmission. is that correct?.........I also suspect that you might be reading the interior trim color on the label.......look at the label again and next to the axle code it says TR.....what does it say?

check this out courtesy of Rockledge. even though this TSB is for 2000-2001 suspect the connections anyways.....have you gone though any water lately? http://www.ford-trucks.com/forums/sh...2&postcount=10

I was looking at the 4th position from the left (letters seperated by "/") and these do seem to be trim colors, seats, ..., so you seem too be right. Further to the right, I see "TR" above the letter "T".

I have heard a few times that OEM replacement parts sometimes fix this sensor problem. Even though foreign made aftermarket parts meet spec, they just don't work the same. Any reason to buy it from Ford ?

As for Auto tranny question : Yes it is auto

As for hit it with a hammer question : I'd like to but won't. Had a gas leak last week so it will probably blow up !!!! Nuts ! It's the Fourth of July and I'd like a show too !!!

it looks like you have the 4R44E http://www.therangerstation.com/tech...AutoTrans.html

Did you read the link that I gave you courtesy of Rockledge?.......I have a duralast sensor in my diff they last about 2 years.

Too simple !!! The 2 leads coming off the sensor, about 2 feet away, had rubbed thru each other and shorted intermitantly. 2 inches of elect tape and problem was gone. Trick was, the break in the wires was just barely inside the wire protection harness where it was screwed to the frame, and could not be seen until I pulled them out a bit. Sometimes you just gotta get in there and root around a bit !!!
