EVAP Purge Flow Sensor Circuit Low

Where it lives

For P0467, the sensor sits on the circuit this code reports. The description of P0467 reports a fault at the sensor.

Check these first

• A failed EVAP purge flow sensor reading low
• A short to ground on the flow sensor signal wire
• Corrosion in the flow sensor connector
• A clogged purge line restricting flow
• An ECM reference voltage fault

What to do next

1. Read the purge flow sensor voltage on a scan tool
2. Check the flow sensor signal wire for a short to ground
3. Inspect the flow sensor connector for corrosion
4. Check the purge line for a restriction
5. Replace the flow sensor if the voltage stays low
6. Clear the code and retest
