Dtc P0113 Intake Air Temperature (Iat) Sensor High Voltage - Daewoo CIELO EURO III Manual

4. This step simulates a DTC P0112. If the ECM
senses the change, the ECM and wiring are
OK.
5. This step will determine if the reason the ECM
did not sense the change was due to a open ground
or signal circuit or malfunctioning ECM.

DTC P0113 Intake Air Temperature (IAT) Sensor High Voltage

Step
Perform an On-Board Diagnostic (EOBD) System
Check.
1
Is the system check complete?
1. Turn the ignition switch ON, with the engine OFF.
2. Install a scan tool.
2
Is the Intake Air Temperature (IAT) value less than
the specified value?
1. Turn the ignition switch ON, with the engine OFF,
review Freeze Frame data and note the
parameters.
2. Operate the vehicle within the Freeze Frame
3
conditions and Conditions for Setting The DTC as
noted.
Is the IAT sensor value less than the specified val-
ue?
1. Disconnect the IAT sensor electrical connector.
2. Jumper the IAT sensor signal circuit at terminal
2 and the IAT sensor ground circuit at terminal
4
1 together at the IAT sensor electrical connector.
Is the IAT sensor value greater than the specified
value?
Jumper the IAT sensor signal circuit at terminal 2 to
ground.
5
Is the IAT sensor value greater than the value speci-
fied?
Check for a poor connection at the IAT sensor elec-
trical connector and replace any malfunctioning ter-
6
minals if necessary.
Is a repair necessary?
Check the IAT sensor ground circuit for an open and
repair as necessary.
7
Is a repair necessary?
Check the IAT sensor signal circuit for an open or
short to battery and repair as necessary.
8
Is a repair necessary?
Check for a poor IAT sensor ground circuit at termi-
nal M64 or a poor IAT sensor signal circuit ter-
minal B8 (M7)* connection at the
9
engine control module (ECM) and
repair if necessary.
Is a repair necessary?
1. Tur the ignition switch OFF.
10 2. Replace the IAT sensor.
Is the action complete?
