OBD-II Error Code P0467: How to Fix Purge Flow Sensor Low Input

Q: What does error code P0467 mean?

P0467 means the purge flow sensor circuit is reading lower than expected voltage. It's a warning that the EVAP system is not venting properly, often due to a faulty sensor, wiring issue, or vacuum leak.

Q: Can I drive with code P0467?

Yes, but it may cause increased emissions and could lead to a failed emissions test. The vehicle should still run normally, but it's best to fix the issue promptly to avoid potential drivability problems.

Q: How much does it cost to fix P0467?

DIY cost is typically $20–$80 for a new purge flow sensor. If a mechanic does the diagnosis and repair, expect $150–$300 including labor.

Q: What other codes are related to P0467?

Related codes include P0442 (small leak), P0455 (large leak), and P0466 (purge flow sensor high input). These often accompany P0467.

Q: Where is the purge flow sensor located?

The purge flow sensor is usually mounted on or near the EVAP canister, along the hose between the purge valve and the intake manifold. Consult your vehicle's service manual for exact location.

Abstract

Error code P0467 indicates that the engine control module (ECM) has detected a low input from the purge flow sensor in the evaporative emission control (EVAP) system. This usually points to a faulty sensor, wiring issues, or a vacuum leak. Follow the steps below to diagnose and fix the problem.
