Question about 2007 Hyundai Santa Fe Limited

1 Answer

Speedometer no longer works

The speedometer started to oscillate just a few miles/hr. The following day it fluctuated about 10 miles/hr and would occassionally "hang" at 40-42 miles/hr. By the third day, it just stays at zero and the odometer is no longer updating. The dealer, which saw it whille it was still working, said it was the speedo head and wanted $784 for a new gauge cluster (can't get speedo separately) plus tax and labor since the bumper to bumper warranty is out by 7K miles. Any thoughts/suggestions?

    Thanks for answering. The Technician spent about 45 mins. checking out the diagnostics, trying to determine whether it was the sensor or speedo head. He took it for a couple of short trips and after the second one he came back in and stated it was the head though I'm not sure how he came up with this conclusion. I'll try your suggestions and see what happens. Again, thanks!!

Hi did the dealer pull this diagnosis out of hat ? or did you observe him carry out a series of diagnostic checks? i would first check the speed sensor electronis on g/box disconnect and clean/check for corrosion etc ? wd40 spray and dry plug you can test with voltmeter if circuit is ok then re plug and try again? other possibility could be actual sensor fault which you can change diy with a doner sensor which will then eliminate sensor fault? worth checking out before parting with $784+ ? make a thorough check of wires to sensor for any decay etc best of luck from uk ps make sure you pick speedo sensor not reverse light sender to verify put in reverse so light is on then disconnect if still on you have speed sensor?

I have a 2001 chevy venture I changed the vss sensor like 3 time it will work for a few days then I'll start acting up again and the speedometer will stop working how can I fix it?

Do you have any other problems with the vehicle ? Transmission shifting problems , fluctuating idle etc... The vehicle speed sensor does not control the speedometer directly , it is an input to the PCM/ECM - engine computer .
The IPC displays vehicle speed as determined by the PCM. The IPC receives a class 2 message from the PCM. The Vehicle Speed Sensor (VSS) discrete signal is pulled up to ignition voltage in the PCM. The IPC uses the VSS data received from the PCM and a software program to determine the proper vehicle speed to display.
To tell what is happening a factory scan tool needs to be hooked up to check serial data communications between the PCM an instrument cluster . Also could be a bad stepper motor for speedometer , GM had faulty ones back in that year.

I have a 1996 Honda Accord with 268k miles that sputters at the same timethe speedometer needle fluctuates wildly. But I do have a new Vehicle Speed Sensor. This typically only happens when the engin

I am no Honda expert, but a similar problem happened to my ex sister in-laws Ford Taurus. The speed odometer would jump around and it had trouble shifting (automatic transmission). After driving it I changed out the speed odometer sensor on the transmission and it's been fine ever since. I changed out the sensor because if the cars computer cannot tell how fast the car is traveling then fail safes in place go into effect and the computer will do it's best to keep the cars rpm's down based on the speed indicator and not let it shift or shift properly either. If it's getting false speeds then it will shut down the motor when the speed gets to high and allow it to run as the speeds fall (jumping speed odometer needle). It effects the transmission shift points also. It will either shift erratically or not shift out of say 2nd gear, so that the cars engine can't get damaged based on what signal the speed sensor is sending the computer.

My speedometer goes up and down , and my radio goes on and off

The speedometer can fluctuate rapidly under normal driving conditions when the car's speed changes abruptly, but sometimes the needle can start swinging around the dial without any fluctuation in speed. If the hairspring comes loose or breaks, it can't hold the speed cup in place, and the result is a fluctuation in the dial. In electrical speedometers, if the circuit that counts the magnetic pulses fails, it can cause the speedometer read-out to vary from the actual speed and to shoot upward or downward without notice. If a speed sensor in the automatic transmission starts to malfunction, it can affect the speedometer and cause fluctuations. In these instances, either the speedometer or the sensor needs replacement.

Speedometer not working

your problem is with the vehicle speed sensor.
It should be located on the transmission tucked underneath the motor very close to the passenger side axle. If the wires have come off or are corroded, this could be your problem. If the wires and connectors look okay, then most likely, the sensor is bad.

09 Ford Ranger speedometer not working properly

There should be a speed sensor in the transmission for the speedometer and the engine computer. There is a sensor in the rear end for the ABS.
Are you sure you replaced the right sensor ?
