#15 of 35 Found TSB by tmlkcl Sep 09, 2007 (5:25 pm)
TSB EL01099 notes the problem, and there are tons of complaints filed. Not sure how this allworks but probably since not a 'safety' problem, we are on our own. Anybody know how these type things are handles? Where there is a documented problem with tons of complaints but not a clear safety problem?
#16 of 35 Re: 99 4 Runner and 99 Tacoma - both fuel gauges erratic [tmlkcl] by dkrazydingo Sep 20, 2007 (8:23 am)
Replying to: tmlkcl (Sep 09, 2007 2:07 pm) I've had the same problem with a previous car that I had. I found out that the gas censor (in the tank) was loose. I had to access the gas tank, remove the censor and make adjustments. Now, I'm not sure how the censors are on the 4Runner, but you might want to either buy a new censor and drop the gas tank and install it yourself or have someone else do it.   Just a thought!
#18 of 35 Temperature guage in the red by johng10 Sep 02, 2007 (2:55 pm)
2002 4 Runner V6 Temperature guage is in the red Coolant and resavoir is at the proper level, belts and fan are working properly. Upper radiator hose is hot but not extremely. Lower hose is cold which indicates the thermostat has not opened. I can not locate temperature sending unit. Looking for a diagram and any information you can give, Thanks

Replying to: altonvwill (Nov 13, 2007 6:40 pm) Check the brake fluid level. There is a float in the reservior that if your fluid gets low, the light will come on. Also make sure the parking brake lever/pedal is released completely.

Replying to: ojarquin (Oct 10, 2007 11:08 am) My Toyota 4runner 1999 check engine light (CEL) came on five years ago. I paid the dealer $1122.00 to fix it after a few weeks it came back on for a few minutes and disappeared. The dealer told me to bring the car back when the light is on… it came on after a year and the dealer wanted to charge me another $1000. They wanted me to believe if I don’t fix it the car would break apart. I refused and took my car with me. I have driven the car like that for 4 years and the car always runs good. Several mechanics told me not to bother with trashing money at the dealers. The only problems were that red light on the dash, it can be distracting at night and I had to pay about twice the cost of inspection every year. After I spent a hundred dollars for inspection last year I decided to do something about it. I started to research online and within several forums, several contributors said they work or used to work for Toyota dealers and that most of the time the problem is caused by the Mass Air Flow Sensor (MAF), and it is easy to clean it to fix the problem. Some forums even document step by step, with pictures how to clean the MAF. To make sure the MAF is causing the problem you need to get you car scanned and get the error code. If you get P0171 System too Lean (Bank 1), then it is definitely the MAF. Most Auto Zone will scan your car for free. But I decided to buy the device instead from amazon.com: (Actron CP9145 AutoScanner Diagnostic Code Scanner with Live, Record and Playback Data Capability for OBDII (Post-1996) Vehicles) . The device is easy to use. I got the code, I followed the instruction on how to clean the MAF found here: http://www.4x4wire.com/toyota/maintenance/tacoma_4runner_30k/maintenancep5.html , and I have not seen the CEL again since that time. I hope this help.
#22 of 35 Mileage Calculation by mike805 Feb 06, 2008 (6:08 am)
The mileage display in my 2006 4Runner seems to be getting more inaccurate. Driving a combination of city and highway it starts of at as much as 25 mpg and continues to go down to about 21 mpg by the time I have used 3/4 tank of gas. Then when I fill it up the calculated mileage is about 2.5 mpg less (18.5 mpg). Is there any way to correct this display and make it more accurate?

Replying to: mike805 (Feb 06, 2008 6:08 am) 2003 4Runner here. There is nothing that can be corrected. You'll eventually get used to rarely looking at it. Mine is off by about 2 MPG, although it was almost exact when new. I average 15.3 in mostly city driving, so be really happy with your MPG.
#24 of 35 94 4Runner E-brake light by da4runner Jul 18, 2008 (9:40 am)
Hey, all. I got a 94 4Runner 3.0 V6. This morning on my way to work, while I was driving, my e-brake light came on for a second, then turned off, then came on for another second, then went off again. This was while I was in motion and not applying the brakes. The brakes worked fine the whole way to work, and I did not notice any drivability issues. This did happen right after I was adjusting the air conditioner, but that may be cooncidence. What do you guys think? Replies to this message: da4runner (Jul 23, 2008 1:50 pm)
