Ford Transit Connect P0496 Meaning
P0496 is a universal OBDII trouble code. This means that regardless of which make or model of vehicle, the code will mean the same thing. The code technically stands for:
Evaporative Emission System High Purge Flow
The EVAP system captures all fuel vapor from the fuel tank and sends them to the engines intake in order to be ignited in the normal combustion process.
When the Ford Transit Connect computer detects that the EVAP system is purging when it should not be, it will throw the P0496 OBDII code.

PCM– It is possible that the engines computer system itself has gone bad and is registering a P0496 when it shouldn’t be. But, this is definitely not where you want to start.
Wiring– It is possible for shorts in the wiring harness leading to the Vapor Canister Purge Valve has gone bad. Check it.
Fuel Cap– A bad fuel cap can cause the P0496 code to be thrown for sure. Often, you’ll get a message informing you that the fuel cap is off even when it is on.
