4 Wheel Drive/SUVs/speed sensor on 96 Toyota Tacoma 4WD 2.7


Good afternoon, well only turning to you here cause I cannont determine where the speed sensor is located on my 96 Toyota Tacoma 4WD 2.7. I have check the internet, I get different results,one says on the tranny, its not there and other have said in the speedometer cluster.I have recieved a P0500 check engine light and my speedometer does not work. I have tried replaceing the cable but nothing. My smog is due here in Feb and like to figure this out before then, I was told this would not pass smog with a check engine light. Please any help here? I have check and rechecked all the pix on the net etc etc..thx Bernie


From what I can find, there are 2 pieces to the puzzle. On a '96 you have a speedometer cable, unlike the newer Tacomas. Also, all Tacoma 4x4s have a gear driven sending unit on back end of the T-case, right near where the driveshaft comes out. Crawl under your truck and take a look. On your '96 the speedometer cable will attach there.

If you are in California, it will not pass smog with the check engine light on, as the check engine light is part of the visual inspection.

Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you.

I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles, and I suggest that you obtain a repair manual for mechanical problems and do some research before asking your question. Most mechanical questions can't be answered completely without looking at, or listening to the vehicle in person.


40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range. Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland. Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
