The P0096 code indicates that the engine control module has detected a signal from the Intake Air Temperature (IAT) Sensor 2 on Bank 1 that is outside the expected operating range or performance parameters. This sensor typically measures the air temperature after it has passed through a turbocharger or intercooler to help the computer calculate air density and fuel trim.
The sensor element has failed internally or become contaminated, sending an inaccurate voltage signal to the PCM.
Frayed, shorted, or broken wires in the sensor circuit causing signal interference or loss.
Moisture or debris in the sensor connector leading to high resistance or poor electrical contact.
A leak in the charge air piping that allows ambient air to affect the sensor reading inconsistently.
An internal fault in the engine control module's processing circuit for the IAT 2 input.
It is unlikely. This code refers to the electrical performance or range of the sensor signal rather than a restriction in airflow.
No. It is very rare for the PCM to fail in a way that triggers P0096; the issue is almost always found in the sensor or the wiring.
Depending on the vehicle, the PCM may use a default temperature value to protect the engine, which can result in reduced power or limited RPMs.
