Why is my car speedometer not accurate?

Reasons why your speedometer is inaccurate

Damaged wiring or a blown fuse could be enough to through the speedometer out of whack. A malfunctioning sensor or engine control unit could be reporting an erroneous speed. A change in wheel or tire size could even throw off the senor and its calculations.

When should I calibrate my speedometer?

Discount Tire recommends that you recalibrate your speedometer every time you change your tire size. This is so you are able to safely operate on the road, ensuring you are not accidentally speeding or dangerously below the flow of traffic speed.

How do you calibrate a car speedometer?

Once you have driven the distance needed, press the button once more and the speedometer will calibrate itself to accommodate the new tire size.

How often should speedometer be calibrated?

All speedometers should be calibrated on a periodic basis, and repaired if out of factory specifications. Specified accuracy varies with make and model and can easily be ± 2 mph or more.

Does putting bigger wheels on your car affect the speedometer?

One of the most common problems a change in your tire and wheel size can cause is an inaccurate speedometer. A larger tire has a higher circumference and fewer rotations as you roll along the highway. Because the tires rotate slower, the speedometer reads this as a lower speed.

Hello, the speed sensor for the speedometer is located on the transmission at the rear extension housing. The housing is the part that the driveshaft slip yoke (front part of driveshaft) would be position at. The sensor is attached with a bolt that needs to be removed, it has a two wire connector going to it.

What causes the speedometer to fluctuate?
