P02EB 2017 Chevrolet Silverado Code - Intake Air Flow Valve Control Motor Current Performance
Quick Answer
The intake airflow valve of diesel engines reduces the intake air flow rate in part-load operation so that a higher exhaust gas recirculation rate can be achieved. Common causes include Faulty Throttle Body Assembly, Throttle Body Assembly harness is open or shorted, Throttle Body Assembly 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 P02EB 2017 Chevrolet Silverado Description
The Intake airflow valve assembly contains a contactless inductive throttle position sensing element that is managed by a customized integrated circuit. The valve position sensor is mounted within the valve body assembly and is not serviceable. The Engine Control Module (ECM) supplies the valve body with a 5 V reference circuit, a low reference circuit, an H-bridge motor directional control circuit, and an asynchronous signal/serial data circuit. The asynchronous signal means communication is only going from the intake airflow valve to the ECM. The Intake Air Flow Valve cannot receive data from the ECM over the signal/serial data circuit. The valve position sensor provides a signal voltage that changes relative to the valve blade angle. The valve position sensor information is transmitted between the Intake Air Flow Valve and the ECM on the signal/serial data circuit.
The valve may also be used to shut down the engine by closing the intake airflow valve and disabling the fuel injectors if the control module detects the engine speed is beyond the desired control limits. The Diagnostic Trouble Code (DTC) will be set if the ECM detects a high current through the throttle motor.
What are the Possible Causes of the DTC P02EB 2017 Chevrolet Silverado?
- Faulty Throttle Body Assembly
- Throttle Body Assembly harness is open or shorted
- Throttle Body Assembly circuit poor electrical connection
- Faulty Engine Control Module (ECM)

Frequently Asked Questions about P02EB 2017 Chevrolet Silverado Code
1. What does the OBDII code P02EB mean on a 2017 Chevrolet Silverado?
P02EB indicates an issue with the Intake Air Flow Valve Control Motor, specifically relating to its current performance, suggesting it may not be operating within expected parameters.
2. What are the common symptoms of the P02EB code on a 2017 Silverado?
Symptoms may include reduced engine performance, a check engine light, poor fuel efficiency, rough idling, or hesitation during acceleration.
3. What causes the P02EB code to appear on a 2017 Chevrolet Silverado?
The code may be triggered by a faulty intake air flow valve control motor, wiring or connector issues, carbon buildup in the intake system, or a malfunctioning powertrain control module (PCM).
4. Can I drive my 2017 Chevrolet Silverado with the P02EB code?
While the vehicle may still be drivable, it’s not recommended, as the issue can lead to decreased performance and potential long-term engine damage if not addressed.
5. How do I diagnose the P02EB code on my Silverado?
Diagnosis typically involves scanning for additional codes, inspecting the intake air flow valve motor and related wiring, and testing the motor's functionality with a multimeter or diagnostic tool.
6. How can I fix the P02EB code on a 2017 Chevrolet Silverado?
Repairs may include cleaning or replacing the intake air flow valve control motor, repairing damaged wiring or connectors, and clearing carbon buildup in the intake system.
7. How much does it cost to repair the P02EB code on a Silverado?
Repair costs can vary, but replacing the intake air flow valve control motor typically costs between $150 and $400, depending on parts and labor.
8. Can a dirty air filter cause the P02EB code?
While a dirty air filter alone is unlikely to cause the code, it can contribute to airflow restrictions, which may worsen related issues.
9. Does the P02EB code require reprogramming the PCM?
Reprogramming the PCM is rarely needed for this code unless there is a confirmed software issue or a PCM malfunction.
10. Will clearing the P02EB code solve the problem?
Clearing the code without addressing the underlying issue will only temporarily turn off the check engine light, and the problem is likely to return.
