Default 05 Speedometer innacuracy

I just bought a 05 Camry LE 4cyl and it seems to have a speedometer problem.
I drive the same route every day (for 27 years) and the general speed is
about 60 to 62 in a 55mph zone. I set the cruise at 60mph when I got my new
Camry everyone goes blowing by me. I now have to go 65-67 mph to just stay
with traffic and even past Sheriffs? I took it in to the dealer and they
said they checked it and it is within the 10% error that Toyota allows? I
can't believe a 10% error is acceptable? They said it read from 60 to 64mph
at a actual speedo reading of 60. I drove past several stationary radar
signs and at a speedo reading of 30mph the radar indicated 25. At a actual
speedo reading of 60 I get 54-55mph on several occasions on a stationary
radar sign. The dealer uses 2 ways to check 1) stopwatch and 2) reading off
the car computer. I would think 1 would be subject to inaccuracy and 2 would
just give what the speedo reads.

I am terribly unhappy with the inaccuracy of this speedo and Toyota's answer
to this problem. I contacted the 1-800 number and a lady from the dealer
called and confirmed the 10% spec and that said Toyota does not seem to be
as picky about specs any more??? I actually would not have bought the car
if I had known the speedometer was off by 5-6 mph and the dealer does not
think there is a problem.

Has anyone had this experience or have any suggestions.

Steve

Accuracy can depend on tire size and wear.

Steve,
The best way I've found to check a speedo/odo is to use the mile markers on
the roadside. The speedo should be the same accuracy as the odometer.
If you use the trip meter you will be able to check tenths and I've found
it's best to do a 10 mile trip. If your odo is within 5% then I would
consider this normal, if it's 10% I would agree with your dissatisfaction.
At 10% fast you will show 100k when you only have slightly over 90k.
If you find it is 10% and fight with them, ask them if they will extend your
warranty 10%.
HTH, davidj92

Maybe this is Toyota's way of increasing gas mileage. BTW they did use the
mile marker method and came up with 64 or 65 mph at 60 on the speedo. They
claim this is within the 10% spec. The mile marker method leaves alot of
room for slop too as in how do you determine when the odometer is exactly on
the 10th marker. you could be off by a few mph that way. The radar system
showed the error at 5mph at 30mph. Yet Toyota says theyre method of mile
markers is what they use.

Then cars wouldn't be passing you, you would be passing them. This test
indicated that you are going faster than what the speedometer is saying, not
slower.

It sounds to me that this car is going faster than the speedometer and the
other one was going even faster than this one.

Once I bought new tires of the wrong size and I got a speeding ticket
because of it. Maybe the other car you no longer have had the wrong size
tires on them. Tire dealers do this all the time to use the stock that they
have so they don't loose a customer over not having the 'exact' replacement
tire in stock.

Snipped a little:

Generally, Steve, 10% is acceptable to everyone including Law Enforcement.
This is the standard speedo error.

However, check your tire sizes; they may have been replaced with a size
not recommended for your car for one reason or another. There are some
good Tire Size Calculator (Google: tire size calculator miata and tire
size calculator Ram to find two of the best), or at
http://www.tirerack.com. Punch in the recommended size, and, if you want a
bigger 'footprint' you can find another that will keep the same aspect
ration and keep the speedo accurate.

Good luck

Hachiroku,

Thanks for the reply,

Yeah, unfortunately I may be stuck with a near 10% inaccuracy on the
speedo or greater at lower speeds (which the dealer can't verify), which I
never would have expected from Toyota. Like you said, Law enforcement would
not allow for such an error. Oh what a feeling.

The tire site hotlink you posted was very useful for verifying stock tire
size. Since my car was a locate, I was wondering if someone swapped tires
after reading responses to my post. The site you sent me shows 205/65-15s as
being stock size and that is what is on the car. The dealer had said they
checked the tire size and it was OK, but your posted site also confirmed it.

I am going to take my car to a reputable speedometer specialist nearby
and have him go over it and calibrate it at my expense. If the error happens
to be greater than 10% I will attempt to bill Toyota. If not it will be my
treat, but at least it will be accurate.

I will let the group know what the results are.

Steve

Fwiw, those BMW motorcycles that the CHP uses in California had to have some
special speedometers put on because the factory ones always read high by 10%
and then a few mph over that. I was going to send my bike's speedometer off
to Palo Alto Speedometer around the Bay area for calibration. However, they
told me that they cannot do anything to calibrate the odometer which also
read faster (maybe to get it off warranty sooner?!). What made matters
worse to begin with was the speedometer's head came into the U.S. with the
odometer reading in kilometers while the face of it was im MPH. I got
really good miles per gallon numbers with that setup until the dealer
changed it out.

If you have a gps you can get a more accurate speed off of that and then
just learn to live with it.

Reb,
The way I do it is to pull over next to a mile marker, set my trip meter on
odo to zero, go ten miles and pull over at the tenth mile marker. The error,
if any will/should be the same on speedo as odo as it gets its information
from the same source. If your odo shows you went 11 miles when actually it
was 10 then this is a 10% error on the high side and speedo will show 10%
fast.
HTH, davidj92

What they will do will be to open a 'hatch' in the transmission and
replace a gear. Not hard, and the gears are available from Toyota, incase
you go overboard with larger tires.

I can't understand this, though...even when I replaced the stock rubber on
my Tercel, the speedo was only off by 3%, and most of my Toys are off by 1
MPH at 35, if at all...
