Find one of those radar displays that sit on the roadside and tell you how fast you're going. Most likely your GPS is the one that's off, because it has to average and estimate your speed, wheras the vehicle's speedometer should be good from the factory.

95 Silverado 5.7 automatic C2500 Replacement of speed sensor correct 8mph error in my speed. At 60 mph reads out at 68. Checked with GPS.


Are you certain that the correct size of tire is on the truck? A smaller tire will cause the speedometer to register faster speed. If it does have the correct size, the speed sensor would be the cheapest place to start. If that does not fix the problem I would think the speedometer head might need to be either replaced or calibrated.

My 05 Focus speedometer is wacky. All other gauges and systems work fine. The speedometer needle doesn't go to zero when vehicle stops moving.


Sounds like the speedometer is faulty. If the speed sensor were the problem, the odometer would not work correctly, the transmission would not shift correctly, and the check engine light would be on.

Where can I find the wiring diagram for this Chevy Colorado 2007 for the Speedometer. I bought this Truck to this local Car Dealer with Speedometer doesn't function at all. I want to try to see what...


Your speedometer is controlled by your computer network. The vehicle speed sensor (VSS) sends a signal to the Body Control Module (BCM) which then relays the speed sensor data via the UART data lines to the Powertrain Control Module (PCM) and the Instrument Panel Cluster (IPC). To find out why your speedometer is not functioning, you must FIRST scan your ENTIRE computer network for possible fault codes. It is possible that either the VSS is defective or the BCM is not able to relay the information due to a communications fault, or the BCM is relaying the information and the IPC is unable to receive the information due to a communications fault, or the IPC itself is defective. Wiring diagrams will be of no use until you determine which parts of the network is receiving the information from the VSS and which parts are not. This will require the use of a scan tool that can not only read generic OBD fault codes, but also access and display codes and live data from the BCM, PCM and IPC.

Hi, I think 2 things have happened. 1st, when your oil was changed, the technician did not reset the oil life back to 100%. This can be done by turning the key on, without starting the engine, consistantly push the accelerator to the floor fully, 3 times. At the last time, the oil life should reset to 100%. The other issue sounds like a different size tire may have been installed, causing the speedometer to read incorrect. A dealer should be able to reprogram the computer to accept the correct size tire, therefore making the speedometer read correctly. This should not be an issue, unless the current tire size is not accepted in the computer, at this point, you ned to change to the correct size tire, or realize you may be off on the speedometer, and accomodate for your speed accordingly. Good luck...Coop

1998 honda accord speedometer wrong


I I recently went to a government speed awareness workshop (naughty boy!) and asked why all the cars I have recently driven (Vaux Zafira, Vectra, Astra, Honda Accord, Peugeot 106) were indicating a higher speed than my sat-nav. The answer they gave was that car manufacturers will always do this to err on the side of caution for boot-heavy drivers or drivers who neglect to check tyre pressures, so that in a court case they have one less thing to worry about. All these cars indicated about 5-10% over.

Speedometer reading fluctuates


IMHO, I think that the broken cable is what is causing the problems. It "confuses" the programing of the CPU or computer.
