INSPECTION <4056E15FDAC
Caution
The driving test should be carried out by two people at a
placewherefully-openaccelerationcanbedone,and
reading of the measurement values on the pressure gauge
shouldbemade by the person in the passenger seat:
(1)Remove the hose that is connected to the fuel injection
pump boost compensator, and install the pressure gauge
via the Tjoint, as shown in the illustration_
(2) Accelerate the vehicle in second gear (MIT) orL range
(AT) with the throttle fully open, and take a reading of the
measurementvalueonthepressure gaugewhenthe
engine speed reaches approximately 3,000 rlmin:
(3) Ifthepressure isnot positivepressure,thereasonis
probably one of the following, so carry out the following
inspection:
Waste gate actuator is defective
Leaking turbopressure
Turbocharger is defective
(4)If the turbo pressure is 82 kPa (0.84 kg/cm?,12 psi ), the
reasonis probablyan abnormality in the turbo pressure
control, so carry out the following inspection
Wastegateactuator rubber hose is disconnectedor
burst
Waste gate actuator is defective
Waste gate valve is defective
WASTE GATE ACTUATOR INSPECTION <4056, 4M4O>
EI6FEAD
Connect a hand pump (pressurization type) to the nipple_
(2) While gradually increasing the pressure, check the pres-
sure where the waste gate actuator rod begins to move
[approx:Imm (0.04 in.) stroke)]
Standard value:
<4056>82 kPa (0.84 kg/cm?12 psi.)
<4m4O>89 kPa (0.91 kg /cm?13 psi,)
Caution
To prevent damage to the diaphragm,donot apply
pressuremorethan90kPa(0.9kg/ cm?13psi_
<4056> or more than115 kPa (1.17 kg/ cm?17 psi:)
<4m40>
(3) If the value is widely outside the standard value, inspect
theactuatororthewaste gatevalve,andreplace
necessary
