P0467 – OBD-II DTC

OBD-II DTC P0467 – Purge Flow Sensor Circuit Range/Performance

DTC P0467 meaning

DTC P0467 refers to a problem with the Purge Flow Sensor Circuit, indicating that the sensor’s performance is outside the expected range. This sensor is responsible for monitoring the flow of fuel vapor from the charcoal canister to the engine intake, which is crucial for the vehicle’s emissions control system. When the Engine Control Module (ECM) detects that the readings from the purge flow sensor are not within the specified parameters, it triggers this diagnostic trouble code (DTC).

DTC P0467 symptoms

Common symptoms associated with DTC P0467 may include:

• Check Engine Light illuminated
• Decreased fuel efficiency
• Rough idling or stalling
• Increased emissions
• Difficulty starting the engine

DTC P0467 causes

Several factors can lead to the triggering of DTC P0467, including:

• Faulty purge flow sensor
• Wiring issues or damaged connectors in the purge flow sensor circuit
• Vacuum leaks in the EVAP system
• Faulty ECM or software issues
• Clogged or damaged charcoal canister

DTC P0467 seriousness

DTC P0467 can be considered serious as it affects the vehicle’s emissions control system. If left unaddressed, it may lead to:

• Increased emissions, potentially failing emissions tests
• Reduced engine performance and fuel efficiency
• Potential damage to other engine components

How to diagnose DTC P0467

To diagnose DTC P0467, follow these steps:

1. Use an OBD-II scanner to confirm the presence of DTC P0467.
