DTC P0097 [MZR-CD (RF Turbo)]

id0102f1802900

DTC P0097

Intake air temperature (IAT) sensor No.2 circuit low input
DETECTION CONDITION
•  The PCM monitors the input signal from intake air temperature sensor No.2. If the voltage from intake air temperature sensor No.2 is less than 0.1 V, the PCM determines that there is a malfunction in the intake air temperature sensor No.2 circuit.
Diagnostic support note
•  The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle.
•  FREEZE FRAME DATA is available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  IAT sensor No.2 malfunction
•  Connector or terminal malfunction
•  Short to ground in wiring harness between IAT sensor No.2 terminal A and PCM terminal 79
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
•  Verify related service repair information availability.
•  Is any related repair information available?
Yes
Perform repair or diagnosis according to the available repair information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT?
•  Connect the M-MDS to the DLC-2.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine.
•  Is the same DTC present?
Yes
Go to the next step.
No
Intermittent concern exists.
Perform the “INTERMITTENT CONCERN TROUBLESHOOTING”.
(See INTERMITTENT CONCERN TROUBLESHOOTING [MZR-CD (RF Turbo)].)
4
INSPECT IAT SENSOR NO.2 CONNECTOR FOR POOR CONNECTION
•  Turn the engine switch off.
•  Disconnect the IAT sensor No.2 connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 8.
No
Go to the next step.
5
INSPECT IAT SENSOR NO.2 SIGNAL CIRCUIT FOR SHORT TO GROUND
•  Turn the engine switch off.
•  Inspect for continuity between IAT sensor No.2 terminal A (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to ground, then go to Step 8.
No
Go to the next step.
6
INSPECT IAT SENSOR NO.2
•  Inspect the IAT sensor No.2.
•  Is there any malfunction?
Yes
Replace the IAT sensor No.2, then go to Step 8.
No
Go to the next step.
7
INSPECT PCM CONNECTOR FOR POOR CONNECTION
•  Turn the engine switch off.
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to the next step.
No
Go to the next step.
8
VERIFY TROUBLESHOOTING OF DTC P0097 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
No
Go to the next step.
9
VERIFY AFTER REPAIR PROCEDURE
•  Perform the Repair Verification Drive Mode.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
