Speed sensor issue

so i figured out the code my truck is throwing is for the speed sensor, we cleared it and it came right back.

I thought the speed sensor was on the rear axle since it stopped working as soon as the 9" went in, so i was gonna by a speed sensor and try and trick the computer but it looks like the "speed sensor" is on the transmission, and the ABS sensor is on the axle?

but that leads me to ask why the hell is the speedo not working if the speed sensor is on the tranny? and why did it take a few days after the axle went in to throw a code, now the code comes back almost instantly...

Do the ABS sensor and speed sensor work together? I don't know what the code is exactly, but i can go back and get it. they guy cleared it w/o showing me the number.


I may be able to work my way into getting an inspection sticker even if the e-brake and tires are an issue but the computer will fail me if the light is on.

The only sensor that the 99's used was in the rear axle. It controlled speedo, trans shift points, and ABS, among other small things.

You will need to adapt some sort of tone ring and replace the sensor. There is a company that makes them, but I can't think of the name right now. If I figure it out I'll let you know.

Here is what I did to make mine work somewhat properly. I relocated the tone ring to the transfercase output flange. Don't ask how I did it, somebody else offered to do the math and cut the ring. It works, not well, but works. If the math were right it would be perfect.



I can get a picture of the sensor and temporary (turned permanent) bracket that I made for it when I get home if you care.

what's the thing coming off the side of the tranny then? and the computer at Autozone pulled up a speed sensor for my truck as well.

will just plugging a sensor into the wire trick it?

i don't need the speedometer, i have a gps for that.

I know on 01+ the vehicle speed sensor is on the tranny, maybe they changed that in 01.
Does it look like this:

Brea Auto Electric is the company that does the conversion VSS's... they should be able to lead you in the right direction.

If you just need it fooled and not actually working you should be able to get by by plugging the sensor back in and pointing it towards metal. This way it will be sending a signal to the computer saying that it is on and functioning and the vehicle is stationary. This should in theory shut the light off.

And that's way lame that you need this working to get it inspected... and people say CA is a *****... LOL

lol, they look the other way on some crap.. but the inspector can't do anything about what the computer says.



I'll call the shop tomorrow and see if they still have my 8.8, if not i'll buy a sensor, its $19.

My other option is to get a resistor, its supposed to have between a .8 and 1.4 k Ohm resistance so i may just rig something up and leave it at that.

I imagine the other thing on your tranny would be the reverse light switch. The reverse lamp switch is on the body of the transmission. The speed sensor for the manual tranny (excluding 98-00) is located on the extension housing.

Does it look like this:

This pic points to a wiring connector, not the sensor itself. It goes to either the O2 sensor next to the tranny, or the reverse sensor on the tranny.

The '00 2.5L manual has a reverse sensor switch on the tranny, and a speed/ABS sensor on the diff.
