Question about 2005 Chevrolet Impala

1 Answer

Chevy Cavalier 1991 RS 2.2

My Speedometer has seemd to go out on me. I had this problem last year and replaced the speed sensor and also the little motor in my dash. Recently I have noticed problems with the speedometer sticking or jumping. I knew it was a sign of what was to come. Could it be that I picked up a faulty motor? Or could the problem be much bigger? If I had only bought a years older model the cable sounds like it would have been much easier for me. Thank you for your time :0)

Yes the motor is faulty or the circuit that controls it, both the motor and the driver circuit that sends voltage to the motor can cause this issue, have seen both issues many times, I think electronic speedo's are just over complication of a very simple device, i.e. cable driven speedometers.

Recently replaced speedometer sensor on my 2005 Chevy Tahoe speedometer still does not work do you know how to fix it


Yes , replace the stepper motor inside the instrument cluster . The speedometer sensor as you call it is actually a VSS - vehicle speed sensor. If the transmission shifts good an engine runs good it's not the VSS bad. You have to know how it works to fix it . The VSS is an input to the PCM/ECM - engine computer , The PCM/ECM calculates engine speed then sends this info to the instrument cluster over the serial data communication bus . GM has had bad stepper motors in that year vehicle . How to repair GM Instrument Cluster Speedometer Gauge Stepper

Had to replace my starter and now speedometer doesn't work


The starter would have nothing to do with the speedometer not working . What year ,make , model vehicle ! Most vehicles the speedometer is control electronically . The VSS - vehicle speed sensor located on or inside the transmission ,is what the PCM - engine computer uses for speed information . The VSS is an input to the PCM , the PCM sends that information to the instrument cluster over a serial data communication network or data buss , then the instrument cluster controls a little electric motor to control the speedometer . So if the car runs good an shifts good the problem could be the instrument cluster .

Speedometer doesn't work


You might try an oil pressure sending unit, first making sure the connector and harness are okay. I'm not sure, but I think there is a VSS Sensor as well, or vehicle speed sensor. Check the connector and wiring. If its okay, try a sensor. Good luck, hope this helps.

Speedometer not working


run fault codes and look for a speed sensor problem . If the speedo is not reading then any other items requiring a computation of speed/ distance will not work either.

Speedometer is sticking and then jumping up every couple of mph


The speedometer in this truck is electronic, the needle is moved by a tiny electric motor called the speedometer needle stepper motor, a stepper motor is a DC motor than can hold one position rather than just rotate when power is applied to it. You will need to remove the instrument cluster from the truck and send it in to a Ford electronics repair center that repairs speedometers.

Speedometer acting erratic on 99 chevy cavalier


Check the VVS (vehical velocity sensor) "speed sensor", The vss controls shifting and cruise control as well as speedometer. If the Cavalier shift's fine and cruise control work, the it's going to be a good chance that the speedometer n the instrument panel may have a bad connection or the stepper motor needs to be replaced. Get a service book and attempted to check for voltage going to speedo cluster( at dash), to determine if your stepper motor is bad and replace the motor or the whole instrument panel.
Good luck and thank you for using fixya.

Doesn't shift into gear


I recently had this same issue in my 1997 escort. When my speedometer stopped working, my transaxle did not want to shift properly either. This of course caused the check engine light to come on. Without the speedometer working, the transaxle would ride out first gear for a bit until it seemed to "warm up", then it would shift ok. It would seem to slip here and there; especially after slowing to turn a corner. I used my scanner to find a code, and it gave me the code "P0500", which is the speed sensor. I replaced the speed sensor, but that did not cure my issue; I had to take it a few steps further.

My ultimate solution started by removing the instrument cluster from the dash and checking continuity between the speed sensor, and the speedometer. I had 100% continuity between the two, so I looked further. There is a small electric motor that runs the speedometer; it has 6 wires, 2 brown wires, a red wire, a white wire, a blue wire , and a orange wire. I checked the electric motor, and it was bad. I went to the salvage yard and pulled the electric motor and replaced it. After I replaced the electric motor, everything started working as it should.

I hope this information is useful to you as well. Your transaxle may not be bad; the speed sensor alone may fix your issue.
