WASTE GATE ACTUATOR CHECK <4G1>
M1151001200297
AK402022
1. Connect a manual pump (pressure-application
type) to nipple.
CAUTION
In order to avoid damage to the diaphragm, do
not apply a pressure of 75 kPa or higher.
2. While gradually applying pressure, check the
pressure that begins to activate (approximately 1
mm stroke) the waste gate actuator rod.
Standard value: Approximately 60 kPa
3. If there is a significant deviation from the standard
value, check the actuator or the waste gate valve:
replace actuator or turbocharger assembly if
necessary.
