P00EA 2015 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.

Code P00EA 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 detects that the IAT sensor 3 signal is warmer than 149°C (300°F) for at least 5 s.

Frequently Asked Questions about P00EA 2015 Chevrolet Silverado Code

1. What does the OBDII code P00EA mean on a 2015 Chevrolet Silverado?

P00EA indicates that the Intake Air Temperature Sensor 3 Circuit has detected a low voltage condition, which may affect engine performance.

2. What are the common symptoms of the P00EA code?

Symptoms include poor engine performance, reduced fuel efficiency, difficulty starting, and possibly an illuminated check engine light.

3. What causes the P00EA code on a 2015 Chevrolet Silverado?

Common causes include a faulty intake air temperature sensor, damaged wiring or connectors, a short circuit, or a malfunctioning engine control module (ECM).

4. Can a dirty air filter trigger the P00EA code?

While a dirty air filter may not directly cause P00EA, it can lead to restricted airflow, which may contribute to sensor-related issues.

5. How do I diagnose the P00EA code on my Silverado?

Start by inspecting the intake air temperature sensor, wiring, and connectors for damage. Use a multimeter to check the sensor's voltage and resistance, and scan for additional trouble codes.

6. Is it safe to drive with the P00EA code?

Driving with this code is possible but not recommended, as it can lead to reduced engine efficiency and potential long-term damage.

7. How do I fix the P00EA code on my 2015 Chevrolet Silverado?

Repairs may include replacing the intake air temperature sensor, repairing damaged wiring or connectors, or updating/reprogramming the ECM if necessary.

8. How much does it cost to fix the P00EA code?

Repair costs can vary but typically range from $100 to $300, depending on whether the sensor needs replacement or wiring repairs are required.

9. Where is the intake air temperature sensor located on a 2015 Chevrolet Silverado?

The intake air temperature sensor is usually located in the air intake duct, near the throttle body or air filter housing.

10. Can a bad mass airflow sensor cause the P00EA code?

While the mass airflow sensor and intake air temperature sensor work together, a malfunctioning mass airflow sensor is unlikely to directly trigger P00EA. However, itâ€™s worth checking if related codes are present.
