DTC P0113 INTAKE AIR TEMPERATURE CIRCUIT
HIGH INPUT
|
CHECK CURRENT DATA.
Start the engine.
Read the data of intake air temperature sensor signal
using Vehicle Diagnostic Interface
or the OBD-II general scan tool.
|
Note
|
|
•
|
Vehicle Diagnostic Interface
For detailed operation procedure, refer to the “READ
CURRENT DATA FOR ENGINE”.
|
|
•
|
OBD-II general scan tool
For detailed operation procedure, refer to the OBD-II General
Scan Tool Instruction Manual.
|
Is the measured value less than −40°C
(−40°F)?
|
•
|
|
Note
|
|
In this case, repair the following:
|
|
•
|
Poor contact
in intake air temperature sensor
|
|
•
|
Poor contact in ECM
|
|
•
|
Poor contact in coupling connector
|
|
•
|
Poor contact in joint connector
|
|
CHECK HARNESS BETWEEN INTAKE AIR TEMPERATURE SENSOR AND ECM
CONNECTOR.
Turn the ignition switch to OFF.
Disconnect the connector from intake air temperature
sensor.
Measure the voltage between intake air temperature
and manifold absolute pressure sensor connector and engine ground.
Connector & terminal
(B3) No. 4 (+) — Engine ground (−):
Is the measured value more than 10 V?
Repair battery short circuit in
harness between intake air temperature sensor and ECM connector.
CHECK HARNESS BETWEEN INTAKE AIR TEMPERATURE SENSOR AND ECM
CONNECTOR.
Turn the ignition switch to ON.
Measure the voltage between intake air temperature
sensor connector and engine ground.
Connector & terminal
(B3) No. 4 (+) — Engine ground (−):
Is the measured value more than 10 V?
Repair battery short circuit in
harness between intake air temperature sensor and ECM connector.
CHECK HARNESS BETWEEN INTAKE AIR TEMPERATURE SENSOR AND ECM
CONNECTOR.
Measure the voltage between intake air temperature sensor
connector and engine ground.
Connector & terminal
(B3) No. 4 (+) — Engine ground (−):
Is the measured value more than 3 V?

|
Repair harness and connector.
|
|
•
|
|
Note
|
|
In this case, repair the following:
|
|
•
|
Open circuit
in harness between intake air temperature sensor and ECM connector
|
|
•
|
Poor contact in intake air temperature sensor
|
|
•
|
Poor contact in ECM
|
|
•
|
Poor contact in coupling connector
|
|
•
|
Poor contact in joint connector
|
|
CHECK HARNESS BETWEEN INTAKE AIR TEMPERATURE SENSOR AND ECM
CONNECTOR.
Turn the ignition switch to OFF.
Measure the resistance of harness between intake air
temperature sensor connector and engine ground.
Connector & terminal
(B3) No. 5 — Engine ground:
Is the measured value less than 5 Ω?
Replace the intake air temperature sensor.
|
•
|
Repair harness and connector.

|
|
Note
|
|
In this case, repair the following:
|
|
|
•
|
• Open circuit in harness between intake air
temperature sensor and ECM connector
|
|
•
|
• Poor contact in intake air temperature sensor
|
|
•
|
• Poor contact in coupling connector
|
|
•
|
• Poor contact in joint connector
