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
▶ Check short to battery in harness.
▶ If O.K, go to "Ground Circuit Inspection" procedure.
▶ If N.G, repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
▶ Repair open or 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 P0112 INTAKE AIR TEMPERATURE SENSOR1 CIRCUIT LOW INPUT
COMPONENT LOCATION
EC387A43
Refer to DTC P0110.
GENERAL DESCRIPTION
EA0589DC
Refer to DTC P0110.
DTC DESCRIPTION
E3FD8660
Checking output signals of IATS every 20 sec. under detecting condition, if an ouput signal is below 0.1V for more than
10 sec., PCM sets P0112. MIL(Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving
cycle.
DTC DETECTING CONDITION
E698C5D0
Item
Detecting Condition
Possible Cause
DTC Strategy
• This code detects a continuous short to ground
in either the signal circuit or the sensor
Case 1
• Engine running state
• No Vehicle speed sensor fault
• Vehicle speed 〉50kph(30mph)
Enable-
Condi-
tions
Case 2

(More than 10 seconds failure for every
20 seconds test)
MIL On Condition
• 2 Driving Cycles
• Poor connection
• Short to ground in harness
• IATS
• PCM
