DTC P0113 [MZR-CD (RF Turbo)]

BME010200100W27

DTC P0113

IAT sensor No.2 circuit high input

DETECTION CONDITION

• PCM monitors input voltage from IAT sensor No.2 while engine is running. If input voltage from IAT sensor No.2 is above 5.0 V, PCM determines IAT sensor No.2 circuit high input.

POSSIBLE CAUSE

• IAT sensor No.2 malfunction
• Connector or terminal malfunction
• Short to power circuit in wiring between IAT sensor No.2 terminal A and PCM terminal 8
• Open circuit in wiring between IAT sensor No.2 terminal A and PCM terminal 8
• Open circuit in wiring between IAT sensor No.2 terminal B and PCM terminal 91
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
PERFORM DTC CONFIRMATION PROCEDURE
• Perform "DTC Confirmation Procedure".
• Is same DTC present during KOEO or KOER self-test?
Yes
Go to next step.
No
Intermittent concern exists. Go to "Intermittent Concern Troubleshooting".
2
INSPECT POOR CONNECTION OF IAT SENSOR NO.2 CONNECTOR
• Turn engine switch to OFF.
• Inspect for poor connection (damaged, pulled-out terminals, corrosion, etc.).
• Is there any malfunction?
Yes
Repair or replace suspected terminal, go to Step 7.
No
Go to next step.
3
INSPECT IAT SENSOR NO.2 SIGNAL CIRCUIT FOR SHORT TO POWER
• Turn engine switch to ON (Engine OFF).
• Inspect voltage between IAT sensor No.2 terminal A and body GND.
• Is voltage below 1.0 V?
Yes
Go to next step.
No
Repair or replace harness for short to power, go to Step 7.
4
INSPECT IAT SENSOR NO.2
• Inspect IAT sensor No.2.
• Is there any malfunction?
Yes
Replace IAT sensor No.2, go to Step 7.
No
Go to next step.
5
INSPECT POOR CONNECTION OF PCM CONNECTOR
• Turn engine switch to OFF.
• Inspect for poor connection (damaged, pulled-out terminals, corrosion, etc.).
• Is there any malfunction?
Yes
Repair or replace suspected terminal, go to Step 7.
No
Go to next step.
6
INSPECT IAT SENSOR NO.2 CIRCUIT FOR OPEN
• Turn engine switch to OFF.
• Inspect continuity between following harnesses:
- IAT sensor No.2 terminal A and PCM terminal 8.
- IAT sensor No.2 terminal B and PCM terminal 91.
• Is there continuity?
Yes
Go to next step.
No
Repair or replace harness for open, go to next step.
7
VERIFY TROUBLESHOOTING OF DTC P0113 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear DTC from PCM memory using WDS or equivalent.
• Perform KOEO/KOER self-test.
• Is same DTC present?
Yes
Replace PCM, go to next step.
No
Go to next step.
8
VERIFY AFTER REPAIR PROCEDURE
• Perform "After Repair Procedure".
• Is there any DTC present?
Yes
Go to applicable DTC inspection.
No
Troubleshooting completed.
