No codes get set with the 3.3K resistor method.

The direct TPMS system for Toyota vehicles uses a button labeled “SET” below the steering column or in the glove box to reset the system. When you press the button, the system is looking for the sensor IDs that are already stored in the memory.
This button is not a magic button saving you from purchasing TPMS tools and training. In fact, this button can get you into even more trouble if you do not know what you are doing.
Reset Procedure
1. Park the vehicle in a safe place and turn the ignition switch to the "LOCK" position.
2. Adjust the pressure of all installed tires to the specified cold tire inflation pressure level.
3. Turn the ignition key to the "ON" position.
4. Push and hold the tire pressure warning reset switch until the tire pressure warning light blinks slowly three times.
5. Leave the system with the ignition switch in "ON" position for a few minutes, and then turn the ignition key to the "LOCK" position.
Typically, systems use a light on the dash and do not display individual pressures (some 2010 models display pressures in the drive information). When the vehicle is started, the light should illuminate for three seconds and go out if the system is functioning normally. If the light stays on, it means that the system has detected a low tire. The inflation of all the tires (sometimes including the spare) should be checked.
If the light flashes for one minute after the ignition is turned on or continues to flash, it is a sign the system has a malfunction that needs to be diagnosed. On some models, the frequency and length of the flashes can be used to diagnose a problem.
The "SET button" procedure should be used when rotating tires that have different tire pressures in the front and rear, changing or adjusting the tire pressure, or changing tire size, or when tires are replaced.

If you push the button while the vehicle is moving, initialization is not performed. If you push the tire pressure reset switch accidentally and initialization is performed, adjust the tire inflation pressure to the specified level and initialize the system again.

If the tire pressure warning light does not blink slowly three times when you push and hold the reset switch, initialization has failed and the tire pressure warning system may not work properly. In this case, you will need to initialize the system again.

Land Cruisers have a "MAIN/2nd" switch. This allows the owner to have two different sets of tires and wheels, with two different sets of tire pressure warning valve/sensor ID numbers. For example, the second set would be used for snow tires.

If there is a problem with one or more of the sensors communicating with the TPMS module during the reset procedure, it could go into a “looping” mode where it locks out the use of the SET button and the TPMS light will flash. The system is now stuck in this looping mode, and no matter how many times you press the SET button or cycle the ignition, the light will continue to flash.

The only way to stop the looping and the system from looking for sensor IDs not in the memory is to perform a procedure that puts the system into a "learn mode" (see "Stuck in a Loop").


Indirect System
• Scion tC 2005-2006
• Toyota Corolla 2005-2006
• Toyota Matrix 2005-2006
• Toyota Solara 2004-2006
• Toyota Highlander 2004-2006
• Toyota RAV4 2004-2005

Turn the key on (engine off), then press and hold the RESET button until the flashing TPMS warning light goes off. Or, if it is not flashing, hold the RESET button until the light flashes three times. Turn the key off. Note: The relearn procedure is not complete until the vehicle is driven at 19 mph or faster for at least an hour.

Sensor Replacement
Toyota uses either Pacific or TRW sensors and modules. The system monitors more than pressure and temperature, it also looks at the wheel speed sensor, engine RPM and other inputs to make sure the system is operating within set parameters. If the vehicle has a problem with any of the information that is shared along the CAN-BUS, it will not function properly.

Whenever you replace a sensor, module or install a second set of wheels, the new ID numbers for the sensors must be programmed into the system through the OBD II connection. The ID numbers can be found on the sensors. Sometimes it is not until the tire is installed on the rim or the vehicle, that the techs realize they now need those numbers. Some dedicated TPMS tools can collect the IDs by either capturing the periodic transmissions from a sensor, or by activating the sensor by letting pressure out of the tire so that the pressure drops 6 psi within 30 seconds.

After you have the sensor IDs, it is just a matter of following the directions on whatever tool you are using and inputting the IDs. Some tools make it easier than others; some will even tell you if you have to collect an ID from the spare

2009 RAV4 Sport Low tire pressure light on.

I pulled out my tire plug kit and found the "cement" container is empty. went to the shop and they said I don't need it, just the plug should be good. went to the shop and plugged the tire, the light went away after a couple rotation of the wheel. thanks,

I have a 2007 Rav4 and I amunable to locate the reset button for the TPMS system. I looked under and to the left of the sterring wheel like in the picture in the post # 32 but it doesn't have a button there. I looked behind the glove box and was not able to locate it there either. My low tire light come on and blinks for about a minute each time you start the vehicle and then goes to a solid light and does not go out. I have checked all 5 tires and they have the correct pressure. Any help in locating the button would be greatly appreciated.

The 2006...2012 RAV4s don't have a TPMS reset button.

OK, Thanks. Any idea on how to find out why the light won't go off ? If I have a bad sensor, how do I identify which one ?

From the owner's manual:
Quote:
Your vehicle has also been equipped with a TPMS (tire pressure warning
system) malfunction indicator to indicate when the system is not operating
properly. The TPMS (tire pressure warning system) malfunction indicator
is combined with the low tire pressure telltale (tire pressure
warning light). When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously illuminated.
This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure
as intended.
TPMS (tire pressure warning system) malfunctions may occur for a variety
of reasons, including the installation of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pressure
warning system) malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alternate
tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.
Your problem could be the TPMS computer, or, more likely, it could be that the system is not getting a signal from one or more of the sensors. One could have died.

I would order Techstream cable and software. Toyota Techstream and MVCI

It should tell you if the TPMS computer is not working. It will let you read the latest pressure received from each sensor. I guess you could read the pressures. See if one is missing or giving some error indication. Let us know what you learn in the process, as we may be faced with tracking down a failed sensor in the future. Fortunately these are cheaper and more available than they used to be.
