Dtc P0113: Intake Air Temperature Sensor Circuit High - Suzuki Grand Vitara 2011 Manual

1A-95 Engine General Information and Diagnosis: For Petrol Engine Model
Step
5 IAT short circuit check
1) Turn ON ignition switch.
2) Measure voltage between "LT GRN" wire terminal of
MAF and IAT sensor connector and vehicle body
ground.
Is voltage about 0 V?
6 IAT sensor for performance check
1) Check IAT sensor according to "Mass Air Flow (MAF)
and Intake Air Temperature (IAT) Sensor Inspection: For
Petrol Engine Model in Section 1C".
Is it in good condition?

DTC P0113: Intake Air Temperature Sensor Circuit High

Wiring Diagram
Refer to "DTC P0111: Intake Air Temperature Circuit Range / Performance: For Petrol Engine Model".
DTC Detecting Condition and Trouble Area
DTC detecting condition
Voltage of IAT sensor output is more than 4.8 V for 0.5 sec
continuously (Low intake air temperature (high voltage / high
resistance))
(1 driving cycle detection logic)
NOTE
When DTC P0108, P0118 and P0533 are indicated together, it is possible that "GRY/GRN" 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 and pending DTC.
DTC Troubleshooting
NOTE
Before this trouble shooting is performed, read the precautions for DTC troubleshooting referring to
"Precautions for DTC Troubleshooting: For Petrol Engine Model".
Step
1 Was "Engine and Emission Control System Check"
performed?
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?
