P02E3 2016 Chevrolet Silverado Code - Intake Air Flow Valve Control Circuit High Voltage
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 P02E3 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 that the intake airflow valve control circuit voltage is greater than a calibrated.
What are the Possible Causes of the DTC P02E3 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)

4. Can I drive my 2016 Chevrolet Silverado with a P02E3 code?
While the vehicle may still be drivable, continued use can lead to reduced performance and potential engine damage. It’s best to address the issue promptly.
5. How is the P02E3 code diagnosed in a 2016 Chevrolet Silverado?
A technician will inspect the wiring and connectors, test the intake air flow valve, and use a scan tool to monitor voltage and circuit performance.
6. How do I fix the P02E3 code on my 2016 Chevrolet Silverado?
Repairs may include replacing damaged wiring or connectors, repairing or replacing the intake air flow valve, or reprogramming/replacing the ECM if necessary.
7. What tools are needed to diagnose the P02E3 code on a 2016 Chevrolet Silverado?
A diagnostic scan tool, multimeter, and possibly an oscilloscope are typically used to test the circuit and related components.
8. How much does it cost to fix a P02E3 code on a 2016 Chevrolet Silverado?
Costs depend on the issue, but repairs can range from $100 for simple wiring fixes to $500 or more if the intake air flow valve or ECM needs replacement.
9. Can a dirty air filter cause a P02E3 code on a 2016 Chevrolet Silverado?
While unlikely, a severely clogged air filter can contribute to airflow issues that might indirectly affect the intake air flow valve.
10. How can I prevent the P02E3 code from occurring again in my 2016 Chevrolet Silverado?
