I have a 1993 cb7 5-speed with the stock f22 in it. It was my first car and I bought it from the guy that bought it new. I always thought that since I have bought it, I was going slower than everyone else. After passing a few speed detectors, I figured out why. When it says I'm doing 40, I'm going about 38. When I'm doing 50, it says about 45. Then it says 70, and I'm doing 62. I know the first thing I should do is search the forum. I did. I found nothing. So could this be my speed sensor? Gauge cluster? Please help. I drive 80 miles a day to work and cops are everywhere. I really really need this fixed.

Thanks.

Speed sensor is located on the back side of the transmission.

Your numbers are all roughly equivalently proportional:
40/38 = 1.05
50/45 = 1.11
70/62 = 1.13
Your figures were guesstimates it seems, so I would say the electronics and mechanics are probably working just fine. I would chalk this up to worn tread, low tire pressure, or tires different in size from stock. :/

I would clean the sensor, considering you said that it'll be off, then it'll be dead even.
But, I want to know, what kind of shape are your tires in? Are you running the recommended air pressure in your tires? Tread wear? Lastly, can you confirm your tire size? I know that you said that you think they're 195/60/15.. but if they're a different size, even a 205/60/15 or a 195/65/15, it will make a difference.92 Honda Accord LX - Sold
