DTC P0096 | Boost air temperature sensor circuit range/performance problem
--- | ---
DETECTION CONDITION | • If the intake air temperature is higher than the engine coolant temperature by 23 °C {41.4 °F} for 1.2 s with the ignition switch turn to the ON position*, the PCM determines that there is a boost air temperature sensor circuit range/performance problem. *: Ignition switch on when 6 h or more has passed since the ignition switch was turned off Diagnostic support note • This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. • PENDING CODE is available 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 • ECT sensor malfunction • 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 (damaged, pulled-out pins, corrosion, etc.). • 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 • Inspect the boost air temperature sensor. (See BOOST AIR TEMPERATURE SENSOR INSPECTION [L3 Turbo].) • Is there any 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.
5 | INSPECT ECT SENSOR • Inspect the ECT sensor. (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION [L3 Turbo].) • Is there any malfunction? | Yes | Replace the ECT sensor, then go to Step 7. (See ENGINE COOLANT TEMPERATURE (ECT) 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 (damaged, pulled-out pins, corrosion, etc.). • 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 P0096 COMPLETED • Make sure to connect all disconnected connectors. • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine and run it under the FREEZE FRAME DATA condition. • Is the same DTC present? | Yes | Replace the 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.
