Diagnostic Trouble Code (DTC) Charts and Descriptions
P0093 - Fuel System Leak Detected - Large Leak (Continued)
All GO to Pinpoint Test HG.
P0094 - Fuel System Leak Detected - Small Leak
Description: This DTC sets when the PCM detects an air leak that exceeds a calibrated limit for greater than 5 seconds. If
the airflow entering the engine exceeds the airflow through the throttle, a leak is detected.
Possible Causes: • Unmetered air leaks between throttle body and intake valves
• Air leaks at the intake manifold
• Positive crankcase ventilation (PCV) system is leaking
Diagnostic Aids: Verify the integrity of the PCV system. Refer to Section 1, Positive Crankcase Ventilation (PCV) System for
system information.

All GO to Pinpoint Test HG.
P0096 - Intake Air Temperature Sensor 2 Circuit Range/Performance (Bank 1)
Description: This DTC sets when the intake air temperature 2 (IAT2) sensor PID does not correlate with the charge air cooler
temperature (CACT) sensor or the intake air temperature (IAT) sensor PIDs at ignition ON. It also sets if the
IAT2 sensor PID exceeds the maximum calibrated temperature threshold while driving.
Possible Causes: • Slow responding intake air temperature 2 (IAT2) sensor
• Damaged IAT2 sensor
Diagnostic Aids: The IAT2 sensor is located on top of the intake manifold. Aftermarket heaters that are attached to the engine,
transmission or battery may cause DTC P0096 to set in cold weather climates after a 6 hour soak period. This DTC may be accompanied by other DTCs. Check for other DTCs and diagnose those first.

All GO to Pinpoint Test DN.
P0097 - Intake Air Temperature Sensor 2 Circuit Low
Description: This DTC sets when the intake air temperature 2 (IAT2) sensor signal is less than the self-test minimum. The
IAT2 sensor minimum is 0.2 volt.
Possible Causes: • IAT2 circuit short to ground
• Incorrect harness connection
• Damaged IAT2 sensor
Diagnostic Aids: Monitor the IAT2 sensor PID value. A typical IAT2 sensor temperature should be greater than the IAT sensor
temperature.

All GO to Pinpoint Test DN.
P0098 - Intake Air Temperature Sensor 2 Circuit High
Description: This DTC sets when the intake air temperature 2 (IAT2) sensor signal is greater than the self-test maximum.
The IAT2 sensor maximum is 4.6 volts.
Possible Causes: • IAT2 circuit open
• IAT2 circuit short to voltage
• Incorrect harness connection
• Damaged IAT2 sensor
Diagnostic Aids: Monitor the IAT2 sensor PID value. A typical IAT2 sensor temperature should be greater than the IAT sensor
temperature.
