How Do I Calibrate My Truck Speedometer?

If your truck’s speedometer is inaccurate, you can calibrate it yourself with a few tools. First, you’ll need to find a straight stretch of road where you can drive at a consistent speed. Next, use a GPS unit or phone app to track your speed.

Then, compare the two speeds and adjust your speedometer accordingly. To do this, you’ll need to find the odometer calibration screw on your truck (it should be near the speedometer). Turn the screw until the reading on your speedometer matches that of the GPS unit or app.

Once they match up, your speedometer should be accurate!

Where is the Speedometer Calibration Button?

The speedometer calibration button is located on the instrument panel, to the left of the steering wheel. It is a small, round, black button.

Do I Need to Calibrate My Speedometer for Larger Tires?

Most people don’t realize that their speedometer is calibrated for their specific vehicle. This means that if you change the size of your tires, you will need to recalibrate your speedometer so it is accurate. Many people don’t do this and they end up driving too fast or slow because they are relying on an inaccurate speedometer.

It’s actually not that difficult to calibrate your speedometer and there are a few different ways that you can do it. One way is to use a GPS unit. You can drive at a constant speed for a mile and then check the GPS to see how fast you were going.

If your speedometer was off, then you know by how much and you can adjust it accordingly. Another way to calibrate your speedometer is with a radar detector. You can drive at a constant speed and then have someone else measure your speed with a radar detector from behind.

Again, if your speedometer is off, then you’ll know by how much and can adjust it as needed. The best way to ensure accuracy, however, is to take your car into the dealership or service center and have them recalibrate it for you using their own tools and equipment.

Will a Dealership Recalibrate My Speedometer?

Yes, a dealership can recalibrate your speedometer if it is inaccurate. Speedometers can become inaccurate for a variety of reasons, including wear and tear on the vehicle, changes in tire size, or even just driving in different conditions than what the speedometer was calibrated for. If you think your speedometer is inaccurate, take it to your nearest dealership and they should be able to help you out.

2022 Ram 1500 Speedometer Calibration If you’re looking to keep your Ram 1500 running like new, it’s important to stay on top of regular maintenance. Part of that is making sure the speedometer is accurately calibrated.

Here’s a quick guide on how to do that for the 2022 model year. The first step is to connect a reliable speedometer calibration device to your Ram 1500. Once that’s done, you’ll need to drive the vehicle at a consistent speed for about 10 miles.

After that, you can compare the readings on your speedometer with those from the calibration device to see if any adjustments need to be made. If everything looks good, then you’re all set! However, if there is a discrepancy, you’ll need to take your Ram 1500 into a certified dealership service center so they can make the necessary adjustments.

Speedometer Calibration Ram 1500

If your speedometer is reading inaccurately, it might be time for a calibration. Speedometer calibration can ensure that your speedometer is reading correctly, which is important for both safety and legal reasons. If you’re not sure how to calibrate your speedometer, don’t worry – we’ll walk you through the process step-by-step.

First, you’ll need to find a stretch of level ground where you can accurately measure distance. A straight section of road or parking lot will work perfectly. Once you’ve found a good spot, drive at a constant speed for one mile while keeping track of the time with a stopwatch or your car’s odometer.

Next, compare the time it took you to travel one mile with the number that your car’s odometer showed for that same distance. If they match up, then your speedometer is already accurate and doesn’t need any further adjustment. However, if there’s a discrepancy between the two numbers, you’ll need to make some adjustments.

To adjust your speedometer, locate the screw or knob on the back of the gauge cluster that controls calibration. From there, simply turn it until the needle on the speedometer matches up with your actualspeed as indicated by the stopwatch or odometer reading. Once everything lines up correctly, re-check your work by driving another mile at a constant speed and comparing the two readings again – they should now match up perfectly!

Mopar Speedometer Calibration

If you own a Mopar vehicle, then you know that one of the most important aspects of driving is keeping an eye on your speed. After all, speeding is one of the leading causes of accidents and tickets. That’s why it’s so important to make sure your speedometer is accurate.

Fortunately, calibrating your Mopar speedometer is a relatively easy process. All you need is a few tools and about 30 minutes of time. Here’s a step-by-step guide to help you get started:

1) Park your car on level ground and set the parking brake. Then, turn off the engine and remove the key from the ignition. 2) Locate the speed sensor on your vehicle.

This is usually located near the transmission or differential. 3) Use a wrench to disconnect the negative battery cable from the sensor. This will prevent any electrical damage while you’re working on the calibration.

4) Use a socket wrench to remove the two bolts that hold the sensor in place. Then, carefully pull out the sensor so you can access the wires. 5) On most sensors, there are three wires: power (usually red), ground (usually black), and signal (usually green).

Locate these colors on your specific sensor before proceeding.


Ram has announced a new speedometer calibration for the 2021 Ram 1500. This will allow drivers to more accurately track their speed and avoid speeding tickets. The calibration is available for both the eight-speed automatic and six-speed manual transmission models.
