P02EB 2016 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 2016 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 2016 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)
How to Fix the DTC P02EB 2016 Chevrolet Silverado?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0

Frequently Asked Questions about P02EB 2016 Chevrolet Silverado Code
1. What does the OBDII code P02EB mean on a 2016 Chevrolet Silverado?
P02EB indicates an issue with the Intake Air Flow Valve Control Motor's current performance, suggesting the motor is not operating within the expected parameters.
2. What are the common symptoms of code P02EB in a 2016 Chevy Silverado?
Symptoms may include reduced engine performance, poor fuel efficiency, a check engine light, and irregular engine idling.
3. What causes the P02EB code to appear?
The code can be triggered by a faulty intake air flow valve control motor, wiring issues, poor electrical connections, or a malfunctioning powertrain control module (PCM).
4. Can I drive my 2016 Chevy Silverado with a P02EB code?
While the truck may still be drivable, it’s not recommended to ignore the issue, as it could lead to reduced performance or further damage over time.
5. How do I diagnose the P02EB code on my Silverado?
Start by inspecting the intake air flow valve control motor, checking for damaged wiring or loose connections, and testing the motor’s electrical circuit for proper voltage and current.
6. How can I fix a P02EB code on my 2016 Chevy Silverado?
Repairs may include replacing the intake air flow valve control motor, repairing damaged wiring or connectors, or updating/reprogramming the PCM if needed.
7. Is the P02EB code related to the mass airflow sensor?
No, P02EB specifically pertains to the intake air flow valve control motor and not the mass airflow sensor, although both impact air delivery to the engine.
8. How much does it cost to fix a P02EB code on a Silverado?
Repair costs vary but may range from $200 to $600, depending on whether the motor needs replacement and whether additional electrical repairs are required.
9. Can a dirty intake manifold cause the P02EB code?
Yes, a dirty or clogged intake manifold can restrict airflow, potentially overworking the control motor and triggering the code.
10. Will clearing the P02EB code with a scanner fix the problem?
Clearing the code may temporarily turn off the check engine light, but the underlying issue must be repaired to prevent the code from returning.
