P00EC 2018 Chevrolet Silverado Code - Intake Air Temperature Sensor 3 Circuit Erratic
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.
