OBD-II Code

P0467

Severity

Not yet reviewed

Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.

Can you drive it

We cannot say

Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.

Indicative cost (USD)

$140–$480

From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.

P0467 means the ECM sees the purge flow sensor signal pinned LOW — below the minimum expected voltage threshold (typically below 0.3-0.5V) for an extended period, regardless of commanded purge duty.

How a shop works this

Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.

  1. Note every code that is set, not just this one.

    Codes that appear together usually narrow the cause faster than any one of them read alone.

  2. Read the freeze frame — the conditions the fault was recorded under.

    Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.

  3. Confirm the fault is current rather than history.

    Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.

  4. Then follow the diagnostic notes further down this page, in the order they are written.

    They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.

If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P0467 means the ECM sees the purge flow sensor signal pinned LOW — below the minimum expected voltage threshold (typically below 0.3-0.5V) for an extended period, regardless of commanded purge duty. Either the sensor is dead, the 5V reference is missing, the signal wire is shorted to ground, or the sensor is reading actual zero flow because no vapor is reaching it.

Cheapest-first ladder

  1. Backprobe the purge flow sensor signal pin with KOEO — should sit at baseline 0.5-1.0V on most platforms; reading 0.0V flat means signal-to-ground short OR dead sensor.
  2. Disconnect the sensor and check the 5V reference at the harness side — should read 4.9-5.1V; missing reference means ECM-side wiring fault or blown internal fuse.
  3. Check ground continuity at the sensor harness; corroded grounds drag signal voltage to zero.
  4. Swap-test with a known-good sensor before tearing into wiring — purge flow sensors on Volvo/Hyundai platforms commonly fail internally with the output transistor stuck low, mimicking a wiring fault.
  5. Verify the purge solenoid is actually commanding open — a stuck-closed solenoid means zero flow reaches the sensor, which reads correctly as 0.5V baseline and the ECM blames the sensor. Before condemning the purge flow sensor, scope the purge solenoid driver waveform — if the solenoid never opens, the sensor is innocent and the solenoid (or its driver) is the actual fault ($85 solenoid vs. $350 sensor).

  • 2008-2014Volvo S60/XC60/XC90 throws P0467 from connector pin fretting at the purge flow sensor where the harness clip releases tension over time and the pins back out of full contact; reseat and pack with dielectric grease.
  • 2011-2016Hyundai Sonata/Tucson GDI throws P0467 from a known-failure pattern where the sensor's internal hot-wire fails to baseline-zero — Hyundai TSB territory, check VIN coverage.
  • 2012-2015Kia Optima GDI shares the pattern.
  • 2007-2013Ford Edge/Flex 3.5L throws P0467 from purge line collapse upstream of the sensor (no vapor reaching the element).
  • 2009-2014Audi A4/A6 2.0T throws P0467 from sensor connector corrosion at the engine bay rear bulkhead.

Estimated repair$140 to $480.
