What causes a Ford EGR valve to not work?

A common problem is a rupture or leak in the diaphragm. Check the function of your valve by revving the engine to around 2,000 rpm. If the valve stem does not move, the valve may be faulty. Clean the unit and test again. If faulty, the valve will need to be replaced. Ford EGR systems are known for faulty DPFEs.

What’s the code for an EGR valve throw?

What code will an EGR valve throw have? The P0401 trouble code is related to your car’s exhaust gas recirculation (EGR) system, which controls an engine and reduces emissions. Suppose a computer-controlled valve gives a certain amount of gases back into your engine to be burnt with the air-fuel mixture.

Why does the fuel management light stay on when the EGR is open?

This means the amount of hydrocarbon gases emitted from the tailpipe increases significantly producing a fuel smell. Your engine management light may stay on once your car detects an issue with the EGR valve. This could be caused when the EGR is either constantly closed or open.

What causes black smoke from the EGR valve?

2. Black Smoke from Exhaust. If the EGR valve stays open at all times and the exhaust fumes are being fed to the engine constantly, the engine gets deprived of oxygen. With too much fuel burning and less oxygen, a black smoke gets produced and escapes from the exhaust pipe especially when the car is idle.

What makes a Ford 4.6 EGR valve fail?

Ford EGR systems are known for faulty DPFEs. A bad sensor will illuminate the check engine light and trigger any of the following fault codes: P0171, P0174 and P0401.

Why does my engine stall when the EGR is open?

This is because the temperature is lower so fuel does not burn at the optimal temperature and as a result is less efficient. Stalling when the engine idles like a rough idle is usually caused when the EGR valve is permanently open and is constantly letting exhaust gases into the EGR system.
