P02EB 2018 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 2018 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 2018 Chevrolet Silverado?
- Faulty Throttle Body Assembly
- Throttle Body Assembly harness is open or shorted
- Throttle Body Assembly circuit poor electrical connection

2. What are the common symptoms of code P02EB on a 2018 Silverado?
Symptoms may include reduced engine performance, poor fuel efficiency, a rough idle, or the Check Engine Light turning on.
3. What causes the P02EB code to be triggered?
Common causes include a faulty intake air flow valve control motor, wiring or connector issues, or buildup of carbon or debris in the intake system.
4. Can I drive my 2018 Silverado with a P02EB code?
While it may still be drivable, performance issues and potential long-term engine damage make it important to address the problem promptly.
5. How do I diagnose the P02EB code on my Silverado?
Diagnosis involves using an OBDII scanner to verify the code, inspecting wiring and connectors, and testing the intake air flow valve control motor for proper operation.
6. How can I fix the P02EB code on my 2018 Chevrolet Silverado?
Repairs may include cleaning or replacing the intake air flow valve control motor, repairing damaged wiring, or clearing debris from the intake system.
7. What tools are needed to repair the P02EB code?
You may need an OBDII scanner, multimeter, and basic tools for inspecting and replacing the intake air flow valve control motor or connectors.
8. How much does it cost to fix a P02EB code on a Silverado?
Repair costs depend on the underlying issue. Replacing the motor could range from $100 to $300, while labor and diagnostics may add $100 to $200.
9. Can a dirty air filter cause the P02EB code?
A dirty air filter alone is unlikely to directly cause this code, but it can contribute to airflow restrictions, which may exacerbate related issues.
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 issue will persist if the underlying problem isn’t addressed.
