Gas Tank Size?

[ALBPM]

I don't think that matters..Also, I found some more info: There is a board and sensor that may need to be replaced.

Instruments - Fuel Gauge Calibration Procedure
ELECTRICAL
EL010-99
December 24, 1999
Title:
FUEL GAUGE HORIZONTAL CALIBRATION PROCEDURE
Models:
'99 & '00 4Runner
Introduction
When replacing the meter circuit plate (or) inclination sensor, you must perform the following calibration procedure to ensure proper operation of the Fuel Gauge. This procedure supplements the diagnostic steps for the combination meter.
Applicable Vehicles
-
1999 and 2000 model year 4Runner.
Repair Procedure
1.
After replacing the meter circuit plate or inclination sensor, move the vehicle to a level location. (A surface with an inclination no greater than ±0.5°is the target flatness.)
2.
With the ignition switch in the "OFF" position, press and hold the trip reset button.
3.
Continue pressing the trip reset button while turning the ignition switch to the "ON" position.
4.
Within 5 seconds of turning the ignition switch "ON", release the trip switch, press the trip switch 3 times, and on the third press hold the switch for 5 seconds. The buzzer will sound for 1 second at 800 HZ.
5.
After the buzzer stops, release the trip switch.
6.
Press the trip switch one more time and hold for 5 seconds. Once more, the buzzer will sound for 1 second at 800 HZ.
7.
The calibration process is completed.
HINT: If in the operation of step 6, the buzzer sounds higher than that of step 5, turn the ignition switch to "OFF" position and repeat the setting procedure from step 2.

Re: gas tank size

I have sputtered and coasted into the gas station and put in 16.5 U.S. gallons. I can go at least 50 to 60 miles after empty light begins to warn me. 1999 3.4L Limited 4WD.

I revived this thread a long time ago with that picture of me filling up with 19 gallons. I was checking my mileage I am getting now and did a quick search for how big our tanks were (because I forgot if it was 15.5 or 18.5). That lead me to this thread and my picture. I kept reading this thread to see if I updated it on my picture, but I apparently never did. After I took that picture, a week or two later, the gas station was shut down. They were diluting the gas with something and calibrating the pumps to deliver less gas than displayed on the screens. So basically I got screwed and it made my engine run like crap. I quickly put two and two together but forgot to update it on here.

Bastards, did it cause any long term effects on your truck?

In my 2000 SR5:
220 miles the light goes on.
13.5 gallons to fill it.
I've never put more than 14.5 gallons in it. Too chicken to run her dry to check the tank capacity.

Well now you guys have me thinking something is wrong with my truck.. My fuel light comes on well before 200 miles. After I get to 200(sometimes even before) the fuel gauge is way under E. I think the most I've gone is between 220 and 230. Sometimes it'll be reading about 130 and I'll fill up with a full 13 to 15 gallons. Yet my Scan Gauge is showing really good average and instant mpg's. So what gives?

Have you calibrated the Scan Gauge?

And if you really are getting ~10mpg, you probably have something to fix mechanically on the engine/truck...

Didn’t even think to calibrate it. Just plugged it in and took drove. For the most part the average has been pretty close to my calculations, around 15 mpg if I can manage to go 220-ish on a tank. I don’t have any cel’s or anything, could it be a fuel pump/filter issue?

Nothing obvious. It ran until about 320K I believe before a mechanic buddy picked it up to take it back to his home town for some R&R. I think any issues I had were strictly due to high mileage at that point.

I got 17.5 gallons into my 1998 last Friday. And it cost me an arm and a leg...

The most I can get into mine is 16.5 gallons and that is with a out-of-gas empty tank.

It may be a 18.5 gallon tank but it doesn't have 18.5 usable gallons.
