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 1S • Connector or terminal malfunction • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS 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 Information availability. • Is any related Service Information available? | Yes | Perform 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. (See BOOST AIR TEMPERATURE SENSOR INSPECTION [L3 Turbo].) • Is there malfunction? | Yes | Replace the MAP/boost air temperature sensor, then go to Step 7. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/BOOST AIR TEMPERATURE SENSOR REMOVAL/INSTALLATION [L3 Turbo].)
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 WDS or equivalent. • Start the engine. • Is the same DTC present? | Yes | Replace PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)
No | Go to the next step.
8 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [L3 Turbo].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [L3 Turbo].)
No | DTC troubleshooting completed.
