Intake Air Temperature Measurement System - Multiple Sensor Correlation Bank 2

Descripción

This code indicates that the engine's computer is detecting a mismatch between multiple sensors that measure the temperature of the air entering the engine on bank 2 (one side of a V-engine). The readings from these sensors don't align.

Pasos de reparación

1. 1 Check for any air intake leaks or restrictions on bank 2 by inspecting intake hoses, clamps, and connections for cracks or loose fittings.
2. 2 Inspect the wiring and connectors for the intake air temperature (IAT) sensors on bank 2, looking for damaged, corroded, or loose connections.
3. 3 Use a scan tool to read live data from all IAT sensors on bank 2 and compare their readings to identify which sensor is out of range.
4. 4 Test the intake air temperature sensor(s) on bank 2 with a multimeter to verify proper resistance values match manufacturer specifications.
5. 5 Replace the faulty intake air temperature sensor(s) on bank 2 if readings are out of specification.
6. 6 Repair or replace any damaged wiring or connectors in the IAT sensor circuits on bank 2.
7. 7 Clear the diagnostic trouble codes and test drive the vehicle to confirm the repair.
8. 8 If all sensors and wiring test good, have the engine control module (ECM) inspected and reprogrammed or replaced by a qualified technician.
