P00E9 2015 Chevrolet Silverado Code - Intake Air Temperature Sensor 3 Circuit Performance

Quick Answer

The Intake Air Temperature (IAT) Sensor 3 is a variable resistor that changes an Engine Control Module (ECM) supplied 5 V signal. Common causes include Faulty Intake Air Temperature (IAT) Sensor 3 (Integrated with the Intake Manifold Pressure and Air Temperature Sensor), Intake Air Temperature Sensor 3 harness is open or shorted, Intake Air Temperature Sensor 3 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P00E9 2015 Chevrolet Silverado Description

The Intake Air Temperature (IAT) Sensor 3 is a variable resistor that changes an Engine Control Module (ECM) supplied 5 V signal. The signal varies with intake manifold air temperature and is displayed by the scan tool as °C (°F). The IAT sensor 3 is integrated with the Manifold Absolute Pressure Sensor in the intake manifold. The ECM provides a ground for the IAT sensor 3 low reference circuit. The Diagnostic Trouble Code (DTC) will be set when the ECM determines the absolute difference between IAT sensor 1 start-up temperature and the IAT sensor 2 start-up temperature that is not at factory specifications.
