Are you driving too slow? Will I get pulled over for going too fast? We are constantly asking these questions when driving. They get answered by taking a quick glance down at your cars cluster to see how fast you are driving. We rely heavily on the it telling us our current speed but may not always wonder if it is actually giving the correct reading or how it actually works.
The speedometer uses the gear ratio of the drive cable, and even the tires diameter to determine the speed. If any of these changes, the speedometer may give you the incorrect reading. You need to get speedometer calibration in order for it to work properly. A speedometer is calibrated by modifying the magnetic field strength using an electromagnet to adjust to match the input from the device’s drive cable. You can try to calibrate it yourself if you are up for the job.
If you have an electric speedometer you would start by determining the distance of the test drive you would need to recalibrate your speedometer, which can be found in the vehicles supporting documents. Press and hold the calibration button located on the speedometer, start the vehicle and then release the button. Press that button again and then take the test drive. Once you have driven the distance needed, press the button once more and the speedometer will calibrate itself to accommodate the new tire size.
