DESCRIPTION
ATF pressure switch No. 2 is installed in the shift solenoid valve ATF output passage. This switch is used to identify the malfunctioning part when a
fail-safe operation is performed. If the shift solenoid valve malfunctions when the ATF pressure switch has a malfunction, a fail-safe operation will
be performed. This fail-safe operation is different from the fail-safe operation performed when the solenoid valve malfunctions and the ATF pressure
switch is normal.
