DESCRIPTION

The tire pressure monitor valve sub-assembly measures tire internal temperature as well as tire pressure, and transmits the information to the tire pressure monitor receiver along with the transmitter ID. If the measured temperature is out of the specified range, the tire pressure monitor ECU recognizes it as a malfunction, outputs DTCs, and blinks the tire pressure warning light.

DTC No.

The temperature inside the tire is outside the range -40 to 215°C (-40 to 419°F).
  1. Tire pressure monitor valve sub-assembly
  2. Tire pressure monitor ECU
  3. Tire pressure monitor receiver assembly
HINT:
It is necessary to perform the procedure to identify the tire pressure monitor valve sub-assembly that is malfunctioning because it cannot be identified by the output DTC.

INSPECTION PROCEDURE

HINT:
Set the tire pressure to the specified value.
1.CHECK TIRE PRESSURE WARNING LIGHT

  1. Check the tire pressure warning light.
