P00EA 2017 Chevrolet Silverado Code - Intake Air Temperature Sensor 3 Circuit Low Voltage
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.

Frequently Asked Questions about P00EA 2017 Chevrolet Silverado Code
What does the OBDII code P00EA mean for a 2017 Chevrolet Silverado?
The P00EA code indicates a low voltage issue in the Intake Air Temperature (IAT) Sensor 3 circuit, which monitors air entering the engine to help regulate performance and emissions.
What are the common symptoms of the P00EA code?
Common symptoms include poor engine performance, reduced fuel efficiency, rough idling, and possibly an illuminated check engine light.
What causes the P00EA code to trigger?
Possible causes include a faulty IAT Sensor 3, damaged or corroded wiring, a loose connector, or issues with the engine control module (ECM).
Is it safe to drive with the P00EA code active?
While the vehicle may still be drivable, ignoring the issue can lead to reduced performance, increased emissions, and potential damage to other engine components over time.
How do you diagnose the P00EA code?
Diagnosis involves using a scan tool to confirm the code, inspecting the IAT Sensor 3 and its wiring for damage, and testing the sensor's voltage and resistance.
Can a dirty air filter cause the P00EA code?
While unlikely, a severely clogged air filter could affect airflow and sensor readings. It's worth checking and replacing the air filter if it's dirty.
How do you fix the P00EA code?
Repairs might include replacing the IAT Sensor 3, repairing or replacing damaged wiring, cleaning corroded connectors, or reprogramming the ECM if needed.
Where is the IAT Sensor 3 located on a 2017 Chevrolet Silverado?
The IAT Sensor 3 is typically located in the intake manifold or air intake duct, depending on the engine configuration.
How much does it cost to repair the P00EA code?
The cost can vary, but replacing the IAT sensor generally ranges from $100 to $300, including parts and labor. Wiring repairs may add to the cost.
Can a bad IAT Sensor 3 affect fuel economy?
