Jim Bird Posted March 21, 2023 Posted March 21, 2023 Have a 1990 16 valve with 40000 miles. Odometer is still working but the speedometer quit just before I put it into winter storage last year. Snow is almost melted and soon time to come out of storage. Need repair suggestions ??? Jim Bird

Jim Bird Jim, the problem is almost always the opposite of what you described, that the SPEEDOMETER needle indicates speed but the ODOMETER numbers do not rotate. If this is what you mean, the repair is a set of small gears that are in the odometer drive which are broken and need replacement. If you feel up to repairing it yourself, you can obtain the gears from ODOMETER GEARS at the website sales@odometergears.com there is also a video available to show you how to do it. If you do not feel up to the repair, you could contact me as I have done likely a hundred or more over the years and would happily repair yours. Contact me in a PM here or get the contact information from your TC Owners Club Newsletter. Edited March 21, 2023 by Hemi Dude Spelling correction (see edit history)

Check the September 2022 Newsletter as you only want to ship the odometer and not the entire instrument cluster. Bob
2Shelbys Posted March 21, 2023 Posted March 21, 2023 If it is indeed the speedo that isn't working it is one of the speed sensors in the trans, probably the output sensor. Replace both. They are side-by-side, easy to access, and inexpensive.

Here is a photo of the 'Distance Sensor' on the transaxle behind the 16V engine. Edited March 21, 2023 by Hemi Dude Photo added (see edit history)
Jim Bird Posted March 21, 2023 Author Posted March 21, 2023 It is indeed the speedo and not the odometer. For a couple of weeks before it completely failed it was intermittently failing ie reading correctly then falling back to zero. It would stay at zero for some time and then for no apparent reason start to function.Finally it stopped working totally. Jim Bird

Jim Bird You wrote "Odometer is still working but the speedometer quit just before I put it into winter storage last year." The way you wrote that would give us the perception that although the speedometer stopped indicating the speed, the ODOMETER continued to register the distance traveled. In any event I would look for a loose connection at the Distance Sensor and if not there, possibly the sensor may be defective. The problem is rarely in the speedometer itself. Some times the adaptor below the Distance Sensor looses contact with the sensor and this can also cause disruption of the signal.

Jim Bird Posted May 4, 2023 Author Posted May 4, 2023 Update on speedo issue. Local transmission shop checked distance sensor. Found sensor and wiring to be good Did a road test with scanner. Got vehicle speed signal on the data stream of the scanner but nothing on the speedo Suggesting that the problem is with the instrument cluster. Any suggestions???
Nile Posted May 7, 2023 Posted May 7, 2023 When the speedo was not working, did the car run poorly and then run fine when it started working?
