CIRCUIT DESCRIPTION

The tire pressure monitor valve sub–assy 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, out-
puts DTCs, and blinks the tire pressure warning lamp.

DTC No.

HINT:
It is necessary to perform the procedure to identify the tire pressure monitor valve sub–assy that is malfunc-
tioning because it cannot be identified by the output DTC.
