P00EB 2014 GMC Sierra Code - Intake Air Temperature Sensor 3 Circuit High 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 P00EB 2014 GMC Sierra Code
1. What does the OBDII code P00EB mean on a 2014 GMC Sierra?
P00EB indicates a high voltage issue in the Intake Air Temperature (IAT) Sensor 3 circuit, which monitors the temperature of air entering the engine for proper fuel and air mixture adjustments.
2. What are the common symptoms of the P00EB code?
Symptoms may include poor engine performance, reduced fuel efficiency, rough idling, difficulty starting, and an illuminated check engine light.
3. What causes the P00EB code to appear?
Common causes include a faulty IAT sensor, damaged or corroded wiring, loose electrical connections, or a malfunctioning ECM (Engine Control Module).
4. How can I diagnose the P00EB code?
Start by visually inspecting the IAT sensor and its wiring for damage or corrosion. Next, use a multimeter to check the sensor's resistance and voltage to confirm if it’s functioning correctly.
5. Can I drive my 2014 GMC Sierra with the P00EB code?
While the vehicle may still be drivable, it’s not recommended. Ignoring the issue can lead to reduced performance, increased emissions, and potential engine damage over time.
6. How do I fix the P00EB code on my GMC Sierra?
Repairs may include replacing the faulty IAT sensor, repairing or replacing damaged wiring, cleaning electrical connectors, or reprogramming the ECM if necessary.
7. Where is the IAT Sensor 3 located on a 2014 GMC Sierra?
The IAT Sensor 3 is typically integrated into the intake manifold or air intake system. Refer to the vehicle’s service manual for exact location details.
8. How much does it cost to repair the P00EB code?
Repair costs vary depending on the issue, but replacing an IAT sensor usually costs $50–$150 for parts and labor. Wiring repairs or ECM issues may increase costs.
9. Can a dirty air filter cause the P00EB code?
A dirty air filter alone is unlikely to cause this code, but it can indirectly affect the IAT sensor by causing restricted airflow or debris accumulation near the sensor.
10. Do I need to clear the P00EB code after repairs?
Yes, after completing repairs, use an OBDII scanner to clear the code and ensure it does not return during subsequent driving cycles.
