jjrbus Posted June 30, 2018 Share Posted June 30, 2018 A Toy owner has been stuck in TX for 2 weeks with a bad VSS, the speed sensor in the transmission on a 91 Toyota, V6, automatic transmission. electronic speedometer, I did a quick search and the the 91 seems to be different than the 92 and up which are available. He says the VSS has been tested and is bad. Anyone know where one, new or used would be available? Quote Link to comment Share on other sites More sharing options...
linda s Posted July 1, 2018 Share Posted July 1, 2018 Looks like the cut off date is 8/91. Before that is a no go and after that they are still available. Not even from Japan sellers which usually have our discontinued stuff. Have them check the production date of their rig and if it's a no go a junk yard is the only option. Found some after market part numbers but looks like all of them are discontinued too. Maybe some one can find them CARQUEST 72-4294 WELLS SU14037 AIRTEX 5S12622 This link shows it was available on a bunch of different vehicles. Sometimes Toyota seems pretty useless.

The transmission uses the same case from 1988 to 1995 so the hole it goes into is the same size. I would try the newer one. Better than being stuck forever.

Linda S I thought about that, the 91 speedometer is a different part #, don't know if that would make a difference or not?? Hmmm, if the computer were the same part # as the toys with the newer VSS could possibly swap out the speedometer????? Quote Link to comment Share on other sites More sharing options...
Maineah Posted July 1, 2018 Share Posted July 1, 2018 It is also is the possibility the speedo gear ratios are different kind of seem unlike they would change the trans build. Quote Link to comment Share on other sites More sharing options...

linda s Posted July 2, 2018 Share Posted July 2, 2018 The reason I think the newer one would fit is that a 1991 Cressida takes the same speed sensor and the campers and that Cressida do not have the same computer. Not even close in part number. Different gear ratio. Maybe if they switched the speed sensor and the speedometer gearing so they matched Linda S That's how I found the alternate after market part numbers. Guy was looking for one for his Cressida. Several years ago though so he probably found them Quote Link to comment Share on other sites More sharing options...
jjrbus Posted July 2, 2018 Author Share Posted July 2, 2018 All gets complicated, I am glad the VSS is available for my 93 so I don't have to look for and carry a spare. I have been watching for a spare ECU to get as a spare, but they are rarer than hens teeth for the Cab and Chassis. Quote Link to comment Share on other sites More sharing options...
Derek up North Posted July 2, 2018 Share Posted July 2, 2018 Re: C&C ECU. It would be nice to know the difference between a 'C&C' and 'Regular' ECU. I doubt you'd find out the difference from a Dealer. A call to a specialized Toyota salvage yard ight get better/more info. It might be as simple a a small change in transmission shift points (perhaps optimized for a 6000lb GVWR). Any change would result in a different Part Number. http://yodajims.com/ I'm sure there aren't too many Toyota motorhomes that have been scrapped because of the 'wrong' ECU being used.

I have only found one reference to the "wrong" ECU being used in an RV. They said it worked with no issue. Hard to put much store in only 1 report on the net. The C&C ECU would be a trip stopper as there are not many available and often the only option is to send in for rebuild. When mine went out there was only 1 available that I could find in the eastern US. Quote Link to comment Share on other sites More sharing options...

linda s Posted July 2, 2018 Share Posted July 2, 2018 There are companies that make speedometer adjusters for people who change rear axle gearing or get giant tires. Commercial speedometer in Sacramento has been use by quite a few Toyota motorhome owners. Cost about 100. Don't really need the factory part but if someone wanted it yes it's still available, 200 bucks for that Linda S Quote Link to comment Share on other sites More sharing options...
ToyotaDave Posted July 14, 2018 Share Posted July 14, 2018 Hi Everybody, I'm the guy with the 1991 Toyota stuck in Tx. The RV is still in Tx and I am back in California. I will check on that speed shop. The part has not been found. I think we will have to get one off of a similar model. I would also be willing to have one made. I am open to suggestions. I have attached pictures of the item I am looking for. Quote Link to comment Share on other sites More sharing options...
sonny sunrader Posted July 17, 2018 Share Posted July 17, 2018 I'm puzzled as to why you can drive the home without the speedo working, just use a Garman or other GPS device. It has a speed reading on it! Quote Link to comment Share on other sites More sharing options...
jjrbus Posted July 17, 2018 Author Share Posted July 17, 2018 VSS sends a signal to the speedometer which converts the signal to something the ECM can use. Without the signal the transmission will not shift right or not at all. Not sure what else is affected? Quote Link to comment Share on other sites More sharing options...
ToyotaDave Posted July 18, 2018 Share Posted July 18, 2018 It also regulates the heat of the engine. With out the sensor there are multiple things not working. I am still looking for this item. The clock is running out for me as I have to bring the car back to Tx I borrowed to get home. I hope I can find one soon. Quote Link to comment Share on other sites More sharing options...

ToyotaDave Posted July 19, 2018 Share Posted July 19, 2018 Thank you Linda! I called, then texted on this part. My main concern is the ECT on the dashboard. I think the sensor also controls it, the ECT is like overdrive but kicks in much faster to get you over hills or mountains. I am keeping my fingers crossed. I do feel I will need to find the part on a similar RV. Again, thank you so much for the link!! You guys on this site are very helpful, it is refreshing to have such a network available.

linda s Posted July 19, 2018 Share Posted July 19, 2018 There is no closer or more correct part than the exact same part number. If we could still buy it at Toyota, the motorhome owner and the Cressida owner would receive exactly the same part. Linda S Quote Link to comment Share on other sites More sharing options...
ToyotaDave Posted July 19, 2018 Share Posted July 19, 2018 (edited) It is a different part, the part I am looking for is Pre-Aug 1991 The Cressida has a cable for the speedometer, the speedometer for this kind of Transmission is controlled by the sensor. We got the part number from looking up the VIN on the RV. We also found that the updated part has the same exact part number. I bought one from Auto Zone in TX. It is very different. Onward and upward! I just spoke to a parts house that specializes in hard to find parts. I hope they can help. I am also contacting anyone parting out 1986-91 Toyota's with a V6, not many out there. So if anyone runs across one I would love to know of it. Edited July 19, 2018 by ToyotaDave date clarification Quote Link to comment Share on other sites More sharing options...
linda s Posted July 19, 2018 Share Posted July 19, 2018 Well then if Toyota did still make it they would have no way of finding the right part for you since part numbers don't seem to mean anything. The Cressida used the a340E transmission the same as the dual wheeled trucks. The E stands for electronically controlled. Not manual cable. All have sensors.

ToyotaDave Posted July 19, 2018 Share Posted July 19, 2018 It is Pre August 1991, seems to be why we have not found the right one. Thank you for your help! Quote Link to comment Share on other sites More sharing options...

Thanks again everyone for your help! OH OH. After posting I decided that it was too easy and went back and double/triple checked the part. It does not seem to fit your application! So I deleted the post, was not up for 10 minutes. Looks like the right part and says for 91 truck, but does not list your vehicle in the applications.

Something has to move to trigger the transducer either a gear or a tone wheel it would be attached to the output shaft not the transducer. If you had two in your hand and they looked the same it probably would work however the accuracy would be questionable. Quote Link to comment Share on other sites More sharing options...

Maineah Posted July 24, 2018 Share Posted July 24, 2018 Because of the final drive ratio, tire size, vintage and the possibility of the transmission being replaced it's going to hard to pin one down with spot on accuracy. Quote Link to comment Share on other sites More sharing options...
