P0467 Fault Code

Purge Flow Sensor Circuit Low Input

• What does that mean?

• Causes
• Solutions

The P0467 fault code indicates a low input signal from the purge flow sensor circuit in a vehicle's evaporative emission control system. This sensor is crucial for monitoring the flow of fuel vapors to ensure they are properly managed and routed to the engine or stored in the charcoal canister. If the signal is too low, it can lead to inefficient fuel vapor management and increased emissions.

What are the symptoms of the P0467 code?

Signs of a potential P0467 error may include:

• Check Engine Light illuminated
• Poor fuel economy due to unregulated fuel vapor flow
• Rough idling or engine performance issues
• Failed emissions test due to increased emissions.

What causes the P0467 code?

Several issues can trigger the P0467 code, including:

• Faulty purge flow sensor
• Damaged wiring or connectors in the sensor circuit
• Issues with the engine control module (ECM)
• Blockages in the evaporative emission system
• Vacuum leaks within the system.

How to fix P0467?

To resolve the P0467 code, consider the following steps:

• Inspect and repair any damaged wiring or connectors associated with the purge flow sensor
• Replace the purge flow sensor if it is determined to be faulty
• Check for and eliminate any vacuum leaks in the system
• Ensure the ECM is functioning correctly and reprogram if necessary.
