2003 Cadillac CTS 3.5L with engine code P0496, high flow

Question

High flow on my purge. I can't find it to replace it in my 2003 Cadillac CTS 3.5L. What do I do?

Answer 1

P0496 Vacuum during non-purge flow condition

The purge solenoid is behind the intake plenum

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 most likely causes for this code include:

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