2002 Nissan Altima speed reading wrong
I just purchased a 2002 Nissan Altima 2.5 and the
speedometer is reading about 5 to 8 mph faster
than I'm actually traveling. I've replaced the speed
sensor but that didn't make a difference. I'm
hoping to get some help please
Did you install tires that are the wrong size?
Sounds like you need to have the speedo/odometer re-calibrated. Usually this happens when wheels and or tires are changed to a different size.
Tires are the correct size, 205/60R16
Have you confirmed that the speedometer is really off using a GPS speedometer on your smart phone?
That's actually how I figured it was not correct. I was wondering why everyone else was passing me. I've had my girlfriend following me and my speed was reading 70 when her speed was 65
On an old car like yours I would allow for the difference and drive accordingly.
Thank you for your feedback, i really appreciate your time
Actually, most cars of that era and older had speedometers that were calibrated to run faster than actual speed. You can check any common car and find this. It was originally intended to be a deterrent to speeding and the "government" thought it would help make roads safer. I like to calculate the difference and install larger tires that bring the cars speed up to the speedometer. It often just takes an upscale of one tire size. See how the people we elect to government are helping us?
