What P0467 means
P means powertrain (engine and transmission). The 0 marks a generic code defined by SAE, so the same number means the same thing across makes. The third character, 4, places it in the auxiliary emission controls subsystem; the last two digits identify the specific fault.
Some vehicles use a purge flow sensor to confirm vapour is actually moving from the canister to the engine when the purge valve opens.
What “Circuit Low” means here
"Low" means the signal or control voltage fell below the minimum the module expects. On a three-wire sensor fed by a 5 V reference, typical causes are a lost 5 V reference (which can affect several sensors sharing it), a signal wire shorted to ground, or a failed sensor.
What you may notice
Symptoms depend on the vehicle and on how the module responds to the fault. Any of these can accompany P0467:
- Usually none
- Purge flow codes stored alongside
Where to start diagnosing P0467
- Check the sensor connector and wiring.
- Confirm the purge valve operates.
- Check for blocked purge lines.
Clear the code only after recording freeze frame data: it shows the engine speed, load and temperature at the moment the fault set, which is often the best clue to reproducing it.
Live data to watch
These standard OBD2 values relate to P0467. Support varies by vehicle; a value your car does not report will simply be missing.
| Value | What to look for |
|---|---|
| Commanded evaporative purge (PID 0x2E) | Context for the flow reading. |

Frequently Asked Questions
What does P0467 mean?
P0467 is the generic SAE J2012 code for "EVAP Purge Flow Sensor Circuit Low". In plain terms, it means the engine computer has detected a "circuit low" fault on the EVAP purge flow sensor.
Can I keep driving with P0467?
Drivable.
What should I check first for P0467?
Check the sensor connector and wiring.
