This code indicates an issue with the third intake air temperature sensor on the side of the engine labeled 'Bank 2'. This sensor's job is to measure the temperature of the air entering the engine, helping the computer adjust fuel delivery for optimal performance.

Pasos de reparación

1. 1 Check the electrical connector at the Intake Air Temperature (IAT) Sensor 3 on Bank 2 for looseness, corrosion, or damage, and reseat it firmly.
2. 2 Inspect the wiring harness running from the IAT Sensor 3 to the ECM for signs of chafing, broken wires, shorts, or heat damage, and repair as needed.
3. 3 Test the IAT Sensor 3 circuit with a multimeter for proper voltage and resistance values according to manufacturer specifications.
4. 4 Replace the Intake Air Temperature Sensor 3 on Bank 2 if readings are out of specification.
5. 5 Clear the diagnostic trouble code and test drive the vehicle to confirm the repair and ensure the code does not return.
6. 6 If the code persists after sensor and wiring repairs, have the Engine Control Module (ECM) inspected and tested by a qualified technician for internal faults.
