Turbocharger Electric Water Pump Inspection

1) Connect 12 V battery terminals to turbocharger
electric water pump terminals.
2) Check if turbocharger electric water pump operates
smoothly without noise.
3) Check if ammeter indicates the specified current.
If measured current is out of specification, replace
turbocharger electric water pump.
Turbocharger electric water pump current at 12 V
1 – 1.3 A at 23 °C, 73 °F
4) Check pumping rate.
Turbocharger electric water pump pumping rate:
More than 850 L/h. (1796 US pt./h., 1496 Imp pt./
h.). at 23 °C, 73 °F
Mass Air Flow (MAF) and Intake Air
Temperature (IAT) Removal and Installation
Removal
1) Disconnect negative cable at battery.
2) Disconnect MAF and IAT sensor connector (1).
3) Remove MAF and IAT sensor (2) from air cleaner
(3).
Engine Electrical Devices: For Diesel Engine Model 1C-33
Installation
S6JB0A1326032 Reverse removal procedure noting the followings.
• Tighten MAF and IAT sensor screws to specified
torque.
Tightening torque
MAF and IAT sensor screw: 6 N·m (0.6 kgf-m, 4.5
lb-ft)
• Tighten turbocharger inlet hose clamp to specified
torque.
Tightening torque
Inlet hose clamp: 2.5 N·m (0.25 kgf-m, 2.0 lb-ft)
• Connect MAF and IAT sensor connector securely.
Mass Air Flow (MAF) and Intake Air
Temperature (IAT) Sensor Inspection
!
Do not heat up MAF and IAT sensor more
than 100 °C (212 °F). Otherwise, MAF and IAT
sensor will be damaged.
• Check sensor O-ring (1) for damage and
deterioration. Replace as necessary.
• Blow hot air to temperature sensing part (2) of MAF
and IAT sensor (3) using hot air drier (4) and measure
resistance between sensor terminals while heating air
gradually.
If measured resistance does not show such
characteristic as shown, replace MAF and IAT sensor.
Intake air temperature sensor resistance
10 °C (50 °F): 3.55 – 3.87 kΩ
20 °C (68 °F): 2.35 – 2.54 kΩ
30 °C (86 °F): 1.61 – 1.73 kΩ
