  Q: How to remove the TPMS Sensor and Transmitter on Toyota Tacoma?

  A:

  The Tire Pressure Warning Valve and Transmitter needs removal by taking off the front and rear tires of the vehicle. Rotating the tire valve cap off while also disposing of the core will evacuate air from the tire chamber. The nut should be removed after sufficient air has escaped and the tire pressure warning valve and transmitter can drop into the tire opening. Save all discarded components including the valve core together with the cap and nut and washer. Remove the tire bead while using the tire remover shoe while being cautious not to harm the sensor by placing it near the tire bead. Pull out the tire bead on the upper side before extracting the tire pressure warning valve and transmitter from the tire opening and then removing the lower tire bead. Before reusing the tire pressure warning valve and transmitter you should remove any grommet that has not sustained damage.

  Q: How to install the TPMS Sensor and transmitter on Toyota Tacoma?

  A:

  Before installing the tire pressure warning valve and transmitter check the valve component's condition since a new unit provides its own grommet which makes separate grommet installation unnecessary. Push the valve component with transmitter through the inside of the rim until the print surface becomes visible from the valve installation hole. The adjustment of valve and transmitter requires checking for oil or water residues which produce improper installation near the rim hole together with the valve washer and the nut. Additionally you should check for visible damage or foreign substances on the valve and transmitter. The transmission signals may fail to function at fast speeds if the unit faces downwards and you must record new unit identification numbers (IDs). Begin the initialization routine only after you properly register transmitter IDs with the tire pressure warning ECU. The new nut and washer need installation from the rim side before torque specification at 4.0 Nm (41 kgf-cm, 35 in-lbf) and verification of washer and nut cleanliness. The wheel disc needs to be placed on a mounting machine where technicians must position the lower tire bead inside the shaded area to protect the valve and transmitter. Steer clear of the valve and transmitter location when you secure the upper bead. Put the valve core in place then inflate the tire before securing loose valve nuts with the specified torque while testing for leaks using soapy water. Proceed to install the specified air pressure on the tires before fixing the valve and transmitter cap. The front and rear wheels need installation with a torque of 113 Nm (1152 kgf-cm, 83 ft-lbf). The Tire Pressure Warning System initialization must be done while all tires have their proper pressure levels set beforehand. Register transmitter IDs before running this procedure. A proper check of the actual tire pressures should appear in the Data List following all repairs.
