DTC P0097:00	Boost air temperature sensor circuit low input
DETECTION CONDITION	• If the PCM detects that the boost air temperature sensor voltage is 0.1 V or less for 5 s, 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 (Mode 2)/Snapshot data is available. • DTCs are stored in the PCM memory.
POSSIBLE CAUSE	• MAP sensor/boost air temperature sensor connector or terminals malfunction • Short to ground in wiring harness between MAP sensor/boost air temperature sensor terminal B and PCM terminal 2N • Boost air temperature sensor malfunction • PCM connector or terminals malfunction • Boost air temperature sensor signal circuit and ground circuit are shorted to each other • PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot data on 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 repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT MAP SENSOR/BOOST AIR TEMPERATURE SENSOR CONNECTOR CONDITION • Turn the ignition switch off. • Disconnect the MAP sensor/boost air temperature sensor connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 8.
3		No	Go to the next step.
4	INSPECT BOOST AIR TEMPERATURE SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND • MAP sensor/boost air temperature sensor connector is disconnected. • Inspect for continuity between MAP sensor/boost air temperature sensor terminal B (wiring harness-side) and body ground. • Is there continuity?	Yes	If the short to ground circuit could be detected: • Repair or replace the wiring harness for a possible short to ground. If the short to ground circuit could not be detected: • Replace the PCM (short to ground in PCM internal circuit). (See PCM REMOVAL/INSTALLATION [L3 Turbo].) Go to Step 8.
4		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 any malfunction?	Yes	Replace the MAP sensor/boost air temperature sensor, then go to Step 8. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/BOOST AIR TEMPERATURE SENSOR REMOVAL/INSTALLATION [L3 Turbo].)
5		No	Go to the next step.
6	INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 8.
6		No	Go to the next step.
7	INSPECT BOOST AIR TEMPERATURE SENSOR SIGNAL CIRCUIT AND GROUND CIRCUIT FOR SHORT TO EACH OTHER • MAP sensor/boost air temperature sensor and PCM connectors are disconnected. • Inspect for continuity between MAP sensor/boost air temperature sensor terminals B and A (wiring harness-side). • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to each other, then go to the next step.
7		No	Go to the next step.
8	VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [L3 Turbo].) • Start the engine. • Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [L3 Turbo].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)
8		No	Go to the next step.
9	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].)
9		No	DTC troubleshooting completed.
