P0445 P0445 OBD-II: Evaporative Emission System Purge Control Valve Circuit Shorted
What P0445 means for you
This code indicates a malfunction in the EVAP system, which can lead to increased emissions and potential vehicle performance issues.
Symptoms
- Check engine light illuminated
- Possible rough idle
- Decreased fuel efficiency
Common causes
- The EVAP system is designed to capture fuel vapors from the fuel tank and direct them into the engine for combustion. When the engine control module (PCM) identifies that there is flow in the EVAP system when it should not be present, it triggers code P0445.
- Issues may arise from a stuck open or closed purge valve, leaks in the EVAP system, or a faulty fuel tank pressure sensor.

Code P0445 signifies a problem with the EVAP system's purge control valve circuit, indicating that the system is detecting flow when it shouldn't. This can affect the vehicle's emissions and overall performance.
How a workshop diagnoses it
1. Inspect the EVAP purge valve for proper operation using a multimeter. 2. Check for any leaks in the EVAP system that could affect pressure readings. 3. Test the fuel tank pressure sensor to ensure it is functioning correctly. 4. Verify the PCM's ability to perform the EVAP leak test and monitor vacuum levels.
