2017-10-10

Description:

  • The fault code P0496 indicates that there is an issue with the evaporative emission system, specifically with the purge flow being too high. This can cause the engine to run poorly and may also result in increased emissions.

Possible Symptoms:

  • Illuminated check engine light

  • Poor engine performance, including hesitation or stalling

  • Increased emissions

  • Fuel odor inside or outside of the vehicle

  • Rough idle or rough running engine

Possible Causes:

  • Faulty purge valve

  • Clogged or restricted canister or hoses

  • Faulty pressure sensor

  • Leaking fuel cap or fuel tank

  • Vacuum leak in the system

Related Parts:

  • Purge Flow Sensor: This sensor helps to prevent fuel vapors in the fuel tank from escaping into the atmosphere. Problems lead to fuel loss

Possible Solutions:

  • Replace the purge valve

  • Clean or replace the canister or hoses as needed

  • Replace the pressure sensor if necessary

  • Check and replace a leaking fuel cap or fuel tank

  • Inspect and repair any vacuum leaks in the system
