What does p0028 mean on an intake valve?
P0028 is a diagnostic trouble code (DTC) for “Intake Valve Control Solenoid Circuit Range/Performance (Bank 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
How does an OBD-II trouble code work?
During the vapor leak test, the ECM commands the vent and purge control valves to close. The ECM then monitors the system for pressure/vacuum loss. If the ECM detects a leak, it records a trouble code.
