2005 highlander tire pressure warning light

[mmendez]

my tire pressure warning light keeps comming on even after checking all the tire pressure, even the spare, and pressing the reset button under the dash. This happend once before and I took it to the dealer and they fixed it. now i am having the same problem. how can i fix this without taking it back to the dealer?

TSB BR006-05 Titled "TIRE PRESSURE WARNING SYSTEM LIGHT ON" outlines the steps to re-initialize the system

You just have to keep holding that button with different combinations of turning on and off my car. The light went off on my 3rd try, the lights really useless. It went off when all my tires are at 35 psi, and doesn't go off went my back right is flat .

Your 35 PSI IS INCORRECT!!!

I hope yu are not trying to save 3 cents on fuel by bumping up your PSI by 5 pounds. The H/L rides like crap, handles poorly and gives lousy foul weather traction. with anything higher than 31PSI anyway. And, the tires WILL have tread feathering on the outer edges with higher NON-Spec. PSI.

The correct PSI is 30. Don't go by the TIRE's sidewall PSI rating. Use Toyota's Drivers Door Jamb lable , it will say 30 PSI>Correct the pressure exactly (per TSB) ,then refer to the TSB on this issue. Follow it exactly.

Do yu have access to this TSB? It is very informative on your TPMS issue!

According to the TSB...Worst case, yu might need a new "Actuator Unit" ! Hope your warranty is in effect!

FYI, the Highlander has an "INDIRECT type Sensor System" and therefore doesn't include the SPARE tire for those that don't know this.

True, for more information refer to the description of this system included in the 2004 Toyota Highlander New Car Features

Thanx TS for the follow up. Great reading. Many people should "Subscribe".


I eat this invaluable stuff for breakfast. I miss Toyota Tech School.

I'm still trying to get Toyotas Navigation "Service Menu" Supplement for the H/L. It is a supplement to the H/L Repair manuals. Toyota publications doesn't offer it! But it does exist for the Dealers.

I viewed it at the dealer. But I can't get my own copy.
