1A-74 Engine General Information and Diagnosis:
DTC P0113: Intake Air Temperature 1 Sensor Circuit High
S7RS0B1104025
Wiring Diagram
Refer to “DTC P0111: Intake Air Temperature Sensor 1 Circuit Range / Performance”.
DTC Detecting Condition and Trouble Area
NOTE
When DTC P0108 and P0118 are indicated together, it is possible that “ORN” wire circuit is open.
DTC Confirmation Procedure
1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Start engine and run it for 10 sec.
4) Check DTC.
DTC Troubleshooting
NOTE
• When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors referring to “Inspection of ECM and Its Circuits”.
• Upon completion of inspection and repair work, perform “DTC Confirmation Procedure” and
confirm that the trouble has been corrected.
DTC detecting condition Trouble area
IAT sensor output voltage is higher than 4.85 V for 0.5 seconds
continuously.
(Low intake air temperature (high voltage/high resistance))
(1 driving cycle detection logic)
• IAT sensor circuit
• IAT sensor
•ECM
Step Action Yes No
1 Was “Engine and Emission Control System Check”
performed?
Go to Step 2. Go to “Engine and
Emission Control
System Check”.
2 IAT sensor and its circuit check
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ON ignition switch.
3) Check intake air temp. displayed on scan tool.
Is –40
°
C (–40
°
F) indicated?
Go to Step 3. Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
