|P0098 – Intake Air Temperature Sensor 2 Circuit High|
|Description: Indicates the sensor signal is greater than the self-test maximum. The intake air temperature 2 (IAT2) sensor maximum is 4.6 volts.
Possible Causes: • IAT2 circuit open or short to voltage
• Incorrect harness connection
• Damaged IAT2 sensor
Diagnostic Aids: Monitor the IAT2 PID value. A typical IAT2 temperature should be greater than the IAT1 temperature.
