2008 Toyota RAV4 Parts Questions & Experts Answers

• Q: How to install the TPMS Sensor sub-assembly on 2008 Toyota RAV4?

  A: Insert the valve into the hole of the rim from the inside so the print surface remains visible. Evaluate the transmitter for signs of deformation and check for damage and abnormalities while confirming no foreign material exists on the inner grommet or rim hole space. When installing the tire pressure warning valve opposite to its proper orientation it produces the risk of damaging both the valve and signal transmission system at fast wheel speeds. The washer installation process starts with placing it on the tire pressure warning valve from the rim side before tightening the nut until it reaches 4.0 Nm (41 kgf-cm, 35 in-lbf). The washer and nut need to be free of foreign contaminants before use while the grommet requires inspection for damage or foreign materials if the tire and valve were removed from the vehicle. Grommet replacement may be necessary if damage or foreign materiel is detected. Check for the absence of oil, water and lubricants in the areas surrounding the rim hole together with the tire pressure warning valve and washer and nut to prevent incorrect installation. Follow inflation of the tire by tightening the valve nut to its specific torque value then inspect for air leaks with soapy water. Position the main body of the valve sensor within the specified shaded area before mounting the wheel disc to the machine while installing the lower tire bead. Safely install the upper tire bead so the tool and sensor have no contact with each other. The installation of front and rear tires demands a torque setting of 103 Nm (1,050 kgf-cm, 76 ft-lbf) and new transmitter ID codes must be registered when replacing the tire pressure warning ECU before inspecting the warning system.
