DTC P0097

Boost air temperature sensor circuit low

DETECTION CONDITION
•  If the PCM detects that the boost air temperature sensor voltage is 0.1 V or less, the PCM determines that the boost air temperature sensor circuit voltage is low.
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The MIL illuminates if the PCM detects the above malfunction condition during first drive cycle.
•  FREEZE FRAME DATA is available.
•  DTCs are stored in the PCM memory.
POSSIBLE CAUSE
•  Boost air temperature sensor malfunction
•  Short to ground circuit between MAP/boost air temperature sensor terminal B and PCM terminal 2N
•  Connector or terminal malfunction
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform the repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT MAP/BOOST AIR TEMPERATURE SENSOR CONNECTOR FOR POOR CONNECTION
•  Turn the ignition switch off.
•  Disconnect the MAP/boost air temperature sensor 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 7.
No
Go to the next step.
4
INSPECT BOOST AIR TEMPERATURE SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND
•  Turn the ignition switch off.
•  Inspect for continuity between the MAP/boost air temperature sensor terminal B (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Repair or replace the wiring harness for a short to ground, then go to Step 7.
No
Go to the next step.
5
INSPECT BOOST AIR TEMPERATURE SENSOR
•  Inspect the boost air temperature sensor.
•  Is there malfunction?
Yes
Replace the MAP/boost air temperature sensor, then go to Step 7.
No
Go to the next step.
6
INSPECT PCM CONNECTOR FOR POOR CONNECTION
•  Turn the ignition 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.
7
VERIFY TROUBLESHOOTING OF DTC P0097 COMPLETED
•  Make sure to connect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine.
•  Is the same DTC present?
Yes
Replace PCM, then go to the next step.
No
Go to the next step.
8
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
