Intake Air Temperature Sensor 3 Circuit High Bank 2

Descripción

This code means the engine computer is seeing a reading from the third intake air temperature sensor on 'Bank 2' that is too high for the current conditions. This sensor is important for the engine to know how dense the incoming air is to properly mix fuel.

Pasos de reparación

1. 1 Check the intake air temperature sensor 3 connector on Bank 2 for loose, corroded, or damaged pins and reseat the connection.
2. 2 Inspect the wiring harness leading to the intake air temperature sensor 3 for signs of a short circuit, chafed insulation, or damage from heat or rubbing.
3. 3 Test the intake air temperature sensor 3 circuit with a multimeter to verify the signal voltage is within specification (a high circuit reading typically indicates an open or short to voltage).
4. 4 Check for related technical service bulletins (TSBs) specific to your vehicle's make and model regarding intake air temperature sensor issues.
5. 5 Replace the intake air temperature sensor 3 on Bank 2 if testing confirms the sensor is reading out of range or has failed.
6. 6 Repair or replace any damaged wiring or connectors in the sensor circuit if a short or open is found.
7. 7 Have the engine control module (ECM/PCM) inspected and tested by a professional if all sensor and wiring checks pass, as a faulty ECM is a rare but possible cause.
