My Fj is 2012 6mt:

The button is located just to the right of the hood release

After airing down I wanted to see if I used the reset button if the low tire light when away...it did..

After I was done airing back up, I use the rest procedure again so that if my tires went below my set pressure enough the light would then come on again instead of being set at the 18 psi.

Not sure what the recommended psi, i check in the am, I have on it now 285/70 R17 Good Year Wrangler Dura-trac- not sure what recommend is on them either but I normally run at 35-36 psi ...pretty sure they were rated up to 50-60 psi.. 11 ply

hope this helps and sorry but being confusing.


Bear with me here, I'm trying to determine if the "set-point" on the TPMS sensors is "fixed", or "adjustable", and some parts of your post are not clear:

1. What year is your FJ?

2. What is the RECOMMENDED tire inflation pressure for the original tires, as shown on the label on the driver's door jamb? (this helps determine if the TPMS sensor actuation point is "fixed", and linked to the recommended inflation pressure for whatever tires were installed when the FJ was built)

3. You performed the initial TPMS reset procedure with all tires set at 18 PSI?

4. Not clear what you mean by "... aired up to 34 PSI and did it again and again ...". Did WHAT again and again .... performed the reset procedure, or reduced tire pressure to 18 PSI, or something else?

5. After doing whatever you did, are you saying that your TPMS indicator light now turns ON at 14 PSI (18 - 4), or turns on at 30 PSI (34-4)?

Reading the entire thread it appears that 2012-2014 have the TPMS Reset button and only a few 2011... \

My 2011 TTSE Mfr-7/11 does not...

I guess I'll have to live with the light on to get good wear/performance out of my tires instead of running high pressured tires and no light.

The batteries in the tire sensors have a maximum life of about 7 years. Crappy system having to replace the sensor as you can't replace the batteries.

Here's an update on re-setting the TPMS light. I recently added 5 "used" TPMS sensors to all wheels plus the spare. When I bought my truck all sensors had been removed, the previous owner was running bead lock wheels and apparently they don't accept such devices.
New sensors run about $60 each I found a company on ebay that sells used sensors however they 100% test and guarantee that they work. I got all 5 for $80 shipping included.
Upon installation, pressure above 35psi and driving 5 miles the light remained on. However the solution was to have the mechanic, with the engine diagnostic screen plugged in, reset all codes. After that walla no more irritating light!

Here is the link to Connected Auto Parts in Arkansas http://stores.ebay.com/Connected-Auto-Parts/OEM-TPMS-Tire-Sensors-/_i.html?_fsub=851129719

'12 through '14 FJs have a TPMS reset button under the dash.

The reset procedure, from the '14 Owner's Manual:

How to initialize the tire pressure warning system

1. Park the vehicle in safe place and turn the engine switch to the LOCK position.
(While the vehicle is moving, initialization is not performed.)

2. Adjust the tire inflation pressure to the specified cold tire inflation pressure level.
Make sure to adjust the tire pressure to the specified cold tire inflation pressure level. The tire pressure warning system will operate based on this pressure level.

3. Turn the engine switch to the ON position.

4. Press and hold the tire pressure warning reset switch until the tire pressure warning light blinks slowly 3 times.

5. Wait for a few minutes with the engine switch in the ON position, and then turn the engine switch to the ACC or LOCK position.
How long is a "few" minutes? I waited for over five minutes and the light still did not reset.

I didn't author the procedure, it's straight from Toyota, but I'd assume that a "few" minutes is less than 3.

You carefully matched the pressure in all FIVE tires, correct?

How exact do they need to match? I don't have a digital pressure gauge, so they aren't exactly the same pressure.

A digital pressure gage isn't inherently more accurate or repeatable than an analog gage, it depends on the quality of the instrument, how roughly it's been treated, storage conditions, etc.

For calibrating the TPMS system, I think you should try to have les than 2 PSI difference between the highest and lowest tire pressures, set cold.

Thanks, I'll fine tune the pressures as best I can and try it again.

What do you mean by "set cold"?

Set cold - tires at ambient temperature, vehicle not driven for several hours to allow tires to cool from whatever temperature they reached while driving.

Tires will always heat up slightly due to flexing of the rubber (hysteresis) in the tread and especially the sidewalls. The higher the speed, the greater the heat buildup, minus the heat extracted by additional airflow across the tire. As the tire heats up, the internal air pressure increases.

Driving on an underinflated tire will cause it to fail due to heat buildup in the sidewall caused by excessive flexing.

Does anyone with access to the wiring diagrams on the 12-14 FJ's care to share the pages relating to where the TPMS reset switch is wired? I would be curious to try and wire one into my 2011 so I can set the pressure when the light would come on.

I know this is an old thread, but helped me with my TPMS indicator. Inflating my spare to the proper psi resolved my issue, but I also found the reset button under the steering wheel on my 2014 FJC.

This just bit me in the butt and I'd be interested in seeing a solution as well (if it exists...). Would much prefer to "re-calibrate on demand" than be at the mercy of pre-programmed limits.

If you wheel enough, then you are airing down & up on a regular basis and no need to TPS. My tire shop wants $60+/- per sensor and the batteries are not replaceable, how stupid is that?
Heres the deal, the TPS is made in bulk by a manufacturer, there cost is $3.75 and they mark it up 100% and sell it to a distributor for $7.50. The Distributor sells them at a 100% mark up to car parts stores for $15, who in return mark it up 100% and sell to tire shops for $30, who put their 100% mark up on it and sell it to us for $60 + installation.

There are hacks on Youtube or on FB Forums showing a quick wire around to permanently disable the monitoring.

Thanks, I used it today for our trip up Antero, worked great after airing down... I hit the sequence.. and the light went off like a charm.. set at 18 lbs... When I aired up to 34 psi and did it again and again the light is set the that pressure... When the pressure gets below 4 psi what they are set for the lights will come on on low tire

so now if my light comes on, it means something <img src="http://www.fjcruiserforums.com/forums/images/smilies/wink.gif" border="0" alt="" title="Wink" class="inlineimg" />
To set it at a lower psi like 18...do you have to lower the pressure in the spare too?

If you have one it will be under the steering wheel next to the hood release lever
You do realize that you are posting on a 13 year old thread with the original poster not being on here for over 6 years?

@R3x. Why are you editing a quote from RogueLeader and not saying anything else? Looks like SPAM to me.

Hannibal. I didn’t release the age of the thread. I’m new here so still navigating 😃
