Question

How do I repair code P0496 on a 2008 Chevrolet Suburban?

Answer 1

P0496 Evaporative emission system flow during non purge

When P0496 occurs there is an undesired purge flow into the fuel tank, the cause for this is the purge control valve stuck open and drawing a vacuum.

Answer 2

The P0496 code indicates a problem with the Evaporative Emission (EVAP) System. The EVAP system is designed to prevent fuel vapors in the gas tank from escaping into the atmosphere by channeling them to the engine for combustion. This code suggests that there is still a flow of emission gases even when the system is supposed to be sealed. The cost depends on the problem. If it is just the Canister Purge Valve (Solenoid), parts and labor cost around $150. The most likely causes for this code include:

• Faulty EVAP Canister Vent Valve
• Faulty EVAP Canister Purge Valve
• Clogged EVAP Canister
• Faulty EVAP Pressure Sensor
