Intake Air Temperature Sensor 2 Circuit Range/Performance

Descripción

This code means the second Intake Air Temperature (IAT) sensor is reporting readings that are outside its expected range or are inconsistent. The car's computer can't make sense of the data it's receiving from this sensor.

Pasos de reparación

1. 1 Check for any loose or disconnected wiring and connectors at the Intake Air Temperature (IAT) sensor 2, cleaning any corrosion or debris found.
2. 2 Inspect the air intake system for leaks, cracks, or loose clamps that could allow unmetered air to affect temperature readings.
3. 3 Verify the IAT sensor 2 is correctly installed and properly seated in its mounting location.
4. 4 Test the IAT sensor 2 resistance values with a multimeter at different temperatures and compare to manufacturer specifications.
5. 5 Check the wiring harness between the IAT sensor 2 and the ECM for damaged, chafed, or shorted wires, and repair as needed.
6. 6 Replace the Intake Air Temperature sensor 2 if resistance values are out of specification or the sensor fails testing.
7. 7 Have the engine control module (ECM) inspected and tested by a professional if all other components check out normal.
