Description
The tire pressure warning valve and transmitter 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 warning ecu recognizes it as a malfunction, outputs dtcs, and blinks the tire pressure warning light.
Hint:
It is necessary to perform the procedure to identify the tire pressure warning valve and transmitter that is malfunctioning because it cannot be identified by the output dtc.
Inspection procedure
Notice:
It is necessary to register an id code after replacing the tire pressure warning valve and transmitter and/or the tire pressure warning ecu (see page tw-9).
Standard pressure: 220 kpa (2.2 Kgf/cm2, 32 psi)

Notice:
Standard pressure: 220 kpa (2.2 Kgf/cm2, 32 psi)
Ok: tire is normal.
Replace tire pressure warning valve and transmitter
Data list
Hint:
By reading the data list displayed on an intelligent
tester, values can be checked, including those of the
switches, sensors, and actuators, without removing any
parts. Reading the data list as the first step of
troubleshooting is one method of shortening diagnostic
time.

Idle control system malfunction
Description
The idling speed is controlled by the etcs (electronic throttle control
system). The etcs is comprised
of: 1) the one valve type throttle body; 2) the throttle actuator, which
operates the throttle valve; 3) the
throttle position (tp) sensor, which detects the opening angle of ...
