Ive been getting glitches lately on my 06 tsx.
For example:
I put a full tank of gas. When i look at the range of miles it started at 400+ and then it automatically dropped to 320 miles when i just drove about 10 miles.
Anyway to fix this?

That's not a glitch. The system is constantly adjusting based upon your driving. You'll notice that the projected range will extend itself if you drive in a very conservative fashion and will decrease if you drive aggressively. Nothing to worry about and certainly nothing that needs fixing.

Alright thanks alot.

quick question, sort of related to that. i used to reset the dash trip meter (in between the tach and speedo) when i refilled, but at that time, the ~350 miles on the dash would read like 352 or 348 on the computer trip/mileage thing in the nav screen. what gives for the discrepancy?

The two systems are not linked and will give different readings since the Nav probably tracks its own distance based on the GPS information while the MID uses the sensors in the car.

^like he said.

the trip computer only gives you a ballpark range of your fuel economy and range. it changes based on the way you drive. it is NOT an accurate way of determining how far you can drive, but in most cases, it serves it's purpose well. just don't rely on it 100%

Yea, to explain this further.
Imagine the satellites orbiting above the earth. The satellites are assuming that all of the roads are completely flat and that there's no hills or grades or anything. So the satellites will measure the physical distances from point A to point B. However, your odometer will measure the distance by how many times the wheels have turned. Or... ACTUAL driving distance.

Quick followup question on the computer's projection of miles remaining before you run empty...

I drove on a tank where the average MPG when I filled up (at the end) came out at 29.2 - my trip odometer, reset at the last fill-up read 396. My miles-to-go came up at close to 0 (low gas indicator on, etc.) Based on this information, I assumed that I would take 13.6 gallons of gas at my fill-up. (Given that the car has a 17.1 gallon tank, why was I getting low gas warnings at this point? Is the rest just reserve?)

Anyway, I ended up putting 14.4 in the car - which seemed surprising. My estimated miles-to-empty (after this fill-up) was 421 - which equals the 29.2 I had on the pior tank multiplied by the 14.4 I took. Could the discrepency be as simple as that I just didn't have a full tank when I previously reset my trip odometer??

Lowest common denominator...in this case, the IQ of the drivers. This is just to keep some idiot from getting the fuel warning light when the car is actually close to running out of fuel and being stranded somewhere.

yeah, i wasn't talking about the estimated mileage left; i was talking about the actual trip computer showing miles traveled. but, thanks everyone else. makes sense.

Well.. there's a built in reserve on both the gas guage the the trip computer. At least for the 04's and 05's. Once the fuel light comes on, it will say something along the lines of at least 20 miles to go until empty on the trip computer. If you look on your fuel guage when the trip computer gets close to "0 miles to go" you will see that the needle isn't completely to the empty mark yet. You can even keep driving a little bit when the needs goes to the E mark and can even drive until it gets below. At this time, the trip computer will just say "-- to go". I wouldn't let it run that low since you never know when you will atually need reserve. But it's got a nice built in as reserve.
