Ford Escape Models 2005 4WD I would like to know, the light of Emission System is on, What this mean.?

P0443 FORD - EVAP Purge Control Circuit Possible causes Faulty Evaporative Emission (EVAP) Purge Solenoid Control Evaporative Emission (EVAP) Purge Solenoid Control harness is open or shorted Evaporative Emission (EVAP) Purge Solenoid Control circuit poor electrical connection What does this mean? When is the code detected? - An improper voltage signal is sent to ECM through the valve. Possible symptoms Engine Light ON (or Service Engine Soon Warning Light) P0443 Ford Description The Evaporative Emission System (EVAP) canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.
Hope this helps

Fault with emissions ( Catalyst ) etc

It's a generic message telling you that it's time to "service" the emission system.

It is an OBD2 Emission System Malfunction,
as are all lights that you get on the dash

You have a possible ABS Braking System Failure

What code do you have this time?

You said Emissions Light--EVAP
System Malfunction !!

it can wait but you better check and see whats wrong. Good luck

You may want to check your oxygen sensor and vacuum hoses. An OBD can help you identify the exact cause. Most auto store and garage should have one.

if you are saying your check engine or service soon light is on, it's bot a biggie. It just means you are not meeting emissions.

If it is flashing, then you are in need of immediate repair due to too much unburned fuel going to your cataltic converter.
