Common Causes of P0445 Code

Understanding the potential causes of the P0445 code can help you diagnose the issue more effectively. Here are some common reasons why this code may appear:

1. Faulty EVAP Purge Control Valve: The most common cause of the P0445 code is a malfunctioning purge control valve, which may be stuck open or closed.
