(3) Remove the air temperature sensor
(4) Use a hair dryer to increase the temperature and measure the
resistance.
Normal conditions:
air temp. sensor
Temperature (ºC)Resistance (kΩ)
Temperature increasesResistance decreases
(5) If the resistance deviates from the standard values, or if it does
not change, replace the air temperature sensor.
(6) Tighten the air temperature sensor to the specified torque.
Tightening torque: 14 ± N·m
4. Inspection of the oil feeder control valve
Checking the operation of the valve
(1) Disconnect the oil feeder control valve connector.
(2) Apply battery voltage across the terminals of the connector on
the oil feeder control valve side, and check that the sound of the
oil feeder control valve operating can be heard.
Caution
There is a chance that the coil may be damaged, so apply
the voltage in as short a time as possible.
Resistance across the terminals
(1) Remove the oil feeder control valve connector.
(2) Measure the resistance across the terminals of the connector on
the oil feeder control valve side.
Standard value: 6.9~7.9 kΩ (when at 20 ºC)
(3) If the resistance deviates from the standard value, replace the oil
feeder control valve.oil feeder control

GENERAL INFORMATION - HOW TO READ THE WIRING DIAGRAMS0-4
Reading Circuit Diagrams
These diagrams show the circuits for each system, from the fuse or fusible link to the earth. In principle, the power supply is
shown at the top and the earth at the bottom, to make it easier to understand the flow of current in the circuit.
The circuit diagrams show a state where none of the switches, etc. are operating.
Indicates power take-out
point.Indicates connector No. The same number is used in the layout
diagrams. Connector numbers shown inside a rounded box indicate
connector symbols that are listed together at the bottom of the page.
Connector numbers that are not shown inside a rounded box indicate
components that are incorporated into the harness.
Indicates that the terminal is
connected via a plate inside
the relay box.
Each circuit diagram is divided into
blocks shown on separate pages.
This number indicates the block.
Indicates the harness branch
point. This number matches the
branch numbers in the other
circuit diagrams.
Indicates the number of the circuit
to which the branch connects.
Indicates the power supply
within the control unit. If no
voltage is indicated, then it is
the battery voltage.
An "X" at the end of a connector
number shows that it is part of the
centralized relay. For more
information, refer to the section
covering the Centralized Junction.
Indicates that circuit diagram
continues at [A] in Block [2].
Indicates the connector symbol,
listed in the order of the connector
numbers in the circuit diagram.
Indicates the operating
conditions of the coolant
temperature switch, etc.Indicates shield
wire.An upward arrow indicates that
the current flows from bottom to
top in the diagram.
