TERMINAL AND CONNECTOR INSPECTION
E056E9B4
Refer to DTC P0110.
SIGNAL CIRCUIT INSPECTION
E66614F6
1.
Check voltage
1)
IG "OFF" and disconnect IATS connector.
2)
IG "ON" and ENG "OFF"
3)
Measure voltage between terminal 4 of IATS harness connector and chassis ground.
Specification : Approx. 5V
4)
Is the measured voltage within specification ?
YES
▶ Go to "Component Inspection" procedure.
NO
▶ Go to " Check short to ground in harness" procedure.
2.
Check short to ground in harness
1)
IG "OFF" and disconnect IATS connector and PCM connector.
2)
Measure resistance between terminal 4 of IATS harness connector and chassis ground.
3)
Measure resistance between terminals 4 and 5 of IATS harness connector.
4)
Measure resistance between terminals 4 and 3 of IATS harness connector.
Specification : Infinite
5)
Is the measured resistance within specification?
YES
▶ Go to "Component inspection" procedure.
NO
▶ Repair short to ground in harness and go to "Verification of Vehicle Repair" procedure.

3)
Is the measured resistance within specification ?
YES
▶ Go to "Check PCM" as follows.
NO
▶ Substitute with a known - good IATS and check for proper operation. If the problem is corrected, replace IATS
and go to "Verification of Vehicle Repair" procedure.
2.
Check PCM
1)
IG "OFF" and connect scantool.
2)
Disconnect IATS connector and connect probe to terminal 4 of IATS harness connector.
3)
IG "ON" and ENG "OFF" and simulation Function on scantool.
4)
Simulate voltage at terminal 4 of IATS harness connector.

5)
Does the signal value of IAT sensor change according to simulation voltage ?
YES
▶ Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deteriora-
tion, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure.
NO
▶ Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM
and go to "Verification of Vehicle Repair" procedure.
NOTE
There is a memory reset function on scantool that can erase optional parts automatically detected and memorized
by PCM. Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others.

DTC P0113 INTAKE AIR TEMPERATURE SENSOR1 CIRCUIT HIGH INPUT
COMPONENT LOCATION
E3BEBEF2
Refer to DTC P0110.
GENERAL DESCRIPTION
E577857C
Refer to DTC P0110.
DTC DESCRIPTION
ECA49F73
Checking output signals of IATS every 20 sec. under detecting condition, if an ouput signal is over 4.9V for more than 10
sec., PCM sets P0113. MIL(Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving
cycle.
