Tire pressure warning light goes on when tire pressure is ok
I have a 2004 Toyota Highlander and the tire pressure warning light goes on even though all tires are at 30 psi. If I have a full size spare, do I need to check it also. If the spare does not matter are there any solutions.

Re: Tire pressure warning light goes on when tire...
If your tire pressures are all set to what they are supposed to be set at, you need to re-calibrate your tire sensors. There is a button that you must hold down for 30 seconds to re-calibrate the tires. This button is located just to the right of the parking-brake. After pressing the button for 30 seconds, the light on your dash should flash several times. Hope this helps.

Once ALL tires have the proper amount of air pressure in them the computer will reset the light. This may take as long as a couple of days (depending on how long you drive the car). Some take as long as 30 minutes of continuous driving to reset.
However, you need to be sure that ALL tires are properly inflated, EVEN THE FULL-SIZED SPARE, if you have a full-sized spare tire.
By operating the tire pressure warning reset switch, the tire pressure warning ECU can be set to issue a warning at an inflation pressure that corresponds to the standard pressure of tires .Therefore, you must set the warning threshold to the proper value in order to comply with the local regulations .Operate the tire pressure warning reset switch only after the inflation pressures of all tires have been adjusted on the vehicle.To initialize the system, press and hold the tire pres- sure warning reset switch for 3 seconds or longer with the ignition switch in the ON position. When the system receives the
initialization signal, the warning light blinks 3 times (1 second on, 1 second off). During initialization, the tire pressure warning valve and transmitter measures the inflation pres sure of the tire, and registers the signals that are transmitted into the tire pressure warning ECU at a frequency of once per minute. The initialization process is completed when signals from all the tires have been received. It takes a few minutes .

2011 Toyota Highlander. Had no luck finding the reset switch, HOWEVER, the warning indicator also includes the SPARE tire (there is a BT sensor in the valve stem which operators on a tiny battery which signals to the car as well). We had filled the 4 vehicle tires properly, and was still showing the tire pressure warning. Researched it and saw the SPARE is include with this monitoring system for the vehicle. Checked and filled the spare, the warning indicator turned off.
turn the key to the on position (not running)
let at least 6 lbs of air out of each tire
put at least 32 lbs of air back in each tire
turn ignition to off
start vehicle and the light and sensors should be reset
Make sure there's 30 psi in each tire. If you have a full size spare, check that as well. If that's good, there should be a reset button under the steering wheel somewhere. Hold it down with the key on or engine running until it blinks 3 times and goes out. If that's no good make sure you still have 4 sensors.
need to have the tire sensors checked sounds like you have one thats bad, if the light comes on and all tires are good then theres a bad sensor, also make sure spare is also full of air, some come with a sensor in the spare also, hope this is helpful, town fair tire can test them for you,
Do you have a full-size spare tire? If so, it too is checked via the Tire Pressure Warning System. Perhaps it is low, this is quite commonly omitted when setting tire pressures. If you have a temporary spare tire, it is not checked. If you have no full-size spare, one of the TWPS sensors may have been damaged by your tire changer. This can happen very easily, if the changer is not careful whilst dis-mounting the tires. A Toyota dealership has a special service tool that will check each of the sensors for output, while on the car. If a sensor is found to be bad, the tester will find it.
You can reset the TPMS system on your Toyota Highlander. There are instructions in the owner's manual on how to do so. However, resetting the system without checking the cold-air inflation of the tires is not necessarily solving the problem. The recommended tire pressure inflation sticker is located on the driver-side door frame. On the Highlander, it calls for 30 pounds per square inch (psi) of tire pressure per tire, including the full-sized spare. If the Highlander had a donut spare tire, it will not have a TPMS sensor and subsequently will not effect the TPMS system one way or the other. To reset the TPMS system in the Highlander, there is a reset button under the driver-side dashboard that needs to be held for a period of time (a few seconds) while the ignition key is in the "key-on/engine-off" mode. The TPMS warning light will blink rapidly for a few more seconds, and the system will reset itself. Refer to the manual for the exact procedure. If the TPMS warning light reoccurs, have the system or tires checked by a professional.Good luck and hope this helps, keep me posted. Be glad to help.
