Intake air temperature sensor 2 is the second air temperature sensor in the intake path; on many turbocharged engines it sits in the intake manifold, often combined with the manifold pressure sensor, and is used to calculate cylinder filling and ignition timing. For P0098, the sensor signal is above its valid range. With the usual voltage-type NTC sensor this means an open circuit or a short to the reference voltage, and the control module reads an extremely low temperature; with sensors that have a frequency output, a high signal corresponds to an extremely high temperature.
Likely causes
Connector loose or corroded, or wire interrupted
Sensor open internally
Sensor ground interrupted
Engine control module faulty
Symptoms
- Check engine light on
- Usually no noticeable symptoms
- Slightly changed power or knock control with an implausible reading
