Hi all,

Just recently I swapped the TOY 8" diff for a Ford 9". I don't have the rear VSS anymore. I'm getting a P0500 code and my speedo isn't working.

I already tried to tap into the front wheel VSS's at the skid control ECU but this did not work.

Any other ideas?

you can install the tone rings in the 9", but I don't know the details. Wyatt at Demello Offroad is smart on this issue, maybe give him a call. Luckily the 4wd's speedo sensor is in the transfer case so mine still works, but of course the abs,vsc, and traction control don't. There's also a speedometer app for the iPhone if you have one of those-

Is there a VSS in the tranny? Mine is 4WD as well but it is my understanding that there are no VSS's on the tranny. Toyota usually uses a VSS1 on the tranny and another backup VSS2. I understand that there is no VSS 1 or 2 on these vehicles.

However according to my diagrams the signal comes from the WSS (wheel speed sensor, aka VSS) it goes something like this:

WSS > skid control ecu > combination meter > ECU (the signal is "conditioned" be the combination meter)

Update:

Pulled a VSS from a Land Cruiser. Wired it as per Wyatt's method and it works just fine. CEL is now off. Still have ABS and e-brake lights on, probably since rear WSS are unplugged. Used a 31 teeth gear on VSS and seems to be a little off, it reads faster than actual vehicle speed. Trying to get a 28 tooth count gear for VSS.

what year/model LC?
interesting to see that a non-Tacoma/Runner VSS works in the new Taco tcases.
junkyard price?
2-wire or 3-wire?

It came from a 1999 HZJ105. This model was not available in the US. However, it uses the same fulltime transfer case found in the USDM 80 and 100 series Land Cruisers.

It is a 3 wire sensor and it was a freebie since the donor vehicle is mine. I still need a VSS to replace that one!

AFAIK there are 2 models of VSS that are very common amongst the entire Toyota/Lexus platforms. They vary on the gear side usually. I believe the stock M/T on an 05 Tacoma uses a 28 teeth gear. It is stamped 28-11 on the plastic gear. The one Im using is 31-11.

very good info!
If, in fact, that vss you have works with the Taco tcases you can order any of the 5 different gears...28, 30, 31, 32, or 33t.
I have all the pt #s in the speedo gear writeup in the faq/tech section.
even if the shafts are different lengths (as in some early Tacos) the gear itself can be pressed on/off what shaft you have with ease.

Cool, I'll look for that writeup.

edit:

Found it!http://www.ttora.com/wiki/index.php/Speedometer_error

Thanks Hy-T!
