SOURCE: speed sensor for a 1996 Century

Dave,

May want to see if the parts store gave you a good sensor or not. Also May want to check and see if you have a transmission input and output sensor as well. these will also give you the same symptoms. Whatever it is, the transmission is not sending the speed signal to your ECU which is in turn not sending the right shift points until its too late causing the hard shifting and also since the ECU doesnt have a speed signal you may not get an odometer/speedometer reading (one or both may go out). Hope this gives you some direction. Good luck. Thanks for using fixya.

SOURCE: 2004 Chev Venture- Speedometer has stopped working

how is your shifting, usually a bad speed sensor will set a check engine light and may cause shift errors, this trans has a internal and external speed sensor, the pcm uses the external for shift and for cruise and for also cruise control. A quick no scanner way to tell is if your cruise is working, if it is then your most likey looking at a bad cluster, take it from me i'm a master gm tech. if i don't have a scanner to do a guage sweep it's like having a broken arm while fixing these. but this should help you out.

SOURCE: My 89 Buick Skylark speedometer reads 10 mph fast.

there is no censor for speed on a buick skylark.
i have an 88 same motor and everything
u jumped a tooth on the gear that drives the needle.
u have to pop the dash off and get to the problem behind the main gauge and the needle assembley should come right out. either that or you stripped the gear and its just going wherever it pleases.

SOURCE: My speedometer stopped working. i have already

I'm not sure with that type of vehicle, but on my 91 S10 my speedometer did not work at all also. The problem with that was the sensor that plugged into my tranny was missing so it was not reading anything. If you have a sensor that goes into the tranny it may be bad or missing so in my opinoin i would try checking that.

SOURCE: speedometer not working properly example

passenger side of vehicle, the tail shaft of the transmission has a VSS (Vehicle Speed Sensor)
that is most likely the culprit, it has a 2 pin plug and a 10MM bolt holding it in.

99 ford Taurus won't go over 35-40 mph, however speedometer reads 120 mph from start. Tranny seems fine and no check lights whatsoever.


Scan the vehicle for fault codes first. Sounds like you need to check the vehicle speed sensor signal into the speedometer. If that is ok then send the speedo head out for repair.

My 2005 Cadillac Deville speedometer goes to zero and transmission seems get stuck and car will not go over 15-20 mph with high engine rpms. Unless I mash on the petal to make it skip gears. #help


problems with speed sensor for transmission. Computer uses a speed signal to shift transmission through the gears. Without speed input, the computer doesn't know when to shift the transmission. Either the speed sensor is bad or wiring from the ECM to the speed sensor is bad. Usually 2 wires lead to the sensor. The sensor generates a AC voltage signal with higher speeds generating more voltage and frequency. The ECM (computer), looks at the signal to see how fast the vehicle is traveling.

I would suspect you have a faulty electronic speedo head, have the cluster removed and have it sent out for repair of the problem. There is no at home repair procedure for this problem, it takes special equip to repair the speedo.

Well i'm going 60 mph but my speedometer read 70 plus for avery mile that i travel the meter read 1 1/3 so my car is gona hit 1k if i still friving like that?


In most cars especially those older models, the speed sensor for the speedometer is located in the transmission. Check for physical wear on the cable that leads from the transmission to the back of the dashboard. If you have increased the size of the tires dramatically, the actual car speed would be slower then the speedometer. Either the components responsible for measuring speed (speed cable, dashboard, speedsensor) is damaged or tire size or transmission parts or the transmission itself was replaced.

Nissan Maxima speedometer reads 20 mph but actual speed is 40-50 mph, is my transmission going bad?


NO, IT'S NOT THE TRANSMISSION! SOUNDS LIKE A SPEEDOMETER PROBLEM! THAT WOULD BE ONE OF THREE THINGS! EITHER THE SPEEDOMETER, THE CABLE, OR THE SPEED SENSOR! THE SPEED SENSOR WILL USUALLY GIVE YOU A P0500 CODE ON AN OBD-II CODE READER! THE SPEED SENSOR IS ELECTRONIC SPEED CONTROL LOCATED ON THE TRANSMISSION! SOME HAVE A SPEEDOMETER CABLE HOOKED TO THEM, AND SOME JUST HAVE A 2 WIRE PLUG THAT HOOKS TO IT!

When i accelarate the speedometer goes to 35 mph and stops. the faster you go, the speedometer drops below 35 mph.


the sppedometer gets a signal from the vehicle speed sensor in the transmission. The speedo cluster then converts that signal nd sends it to the speedo & odometer and to the enine computer. I suspect you have a bad speedo head. Does the odomter record correctly?

Buy a used speeo on Ebay for a good price. Analog (needle) or digital (numbers)?
