When to test the Ford EGR valve solenoid?
The following are the most common symptoms that a Ford (or Mercury or Lincoln) car or truck will usually experience when there’s a fault in the EGR System: Car or truck runs fine, but the check engine light (CEL) is on with an EGR Valve Fault Code: P0401 EGR System Flow Insufficient. P01406 EGR Valve Pintle Position.
What are the symptoms of a bad EGR valve?
Common Symptoms Of A BAD EGR Valve. The following are the most common symptoms that a Ford (or Mercury or Lincoln) car or truck will usually experience when there’s a fault in the EGR System: Car or truck runs fine, but the check engine light (CEL) is on with an EGR Valve Fault Code: P0401 EGR System Flow Insufficient.
Can you clean an EGR valve without removing it?
If you cannot get direct access to the turbo an alternative would be to spray (less effective) into the air duct in the direction of the turbo but please remember to remove the MAF (mass airflow)/air intake sensor first as the cleaner may damage it.

What are the components of the Ford EGR system?
The Ford EGR system uses 3 components: • an EGR valve that opens and closes a passage from the exhaust to the intake manifold, • an Electronic Vacuum Regulator (EVR) that opens and closes passages from the intake manifold to the diaphragm of the EGR valve, and.
Why is my EGR valve not working properly?
If there is a fault in the EGR system, it can cause the EGR not to function properly. Your vehicle’s EGR valve can be faulty due to the accumulation of carbon deposits in its internal surface, pitting, burnt valve, a damaged diaphragm for a vacuum-type EGR valve, or distortion of the valve seat. This problem can also have the following causes:
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.
What does DTC p0403 mean on an EGR circuit?
If there is, it indicates a problem with the solenoid. The EGR solenoid is actuated with a 12-volt power source, switching the solenoid from the “leaking” position to a closed position when power is present. DTC P0403 most commonly indicates an electrical issue with the solenoid or the electrical connections.
What does a bad EGR solenoid do?
One of the first symptoms of a possible problem with the EGR control solenoid is engine performance issues. If the EGR solenoid has any issues, it can cause the finely tuned air fuel ratio to be thrown off. This may result in a decreased power, acceleration, fuel economy, as well as an increase in emissions.
What causes an EGR valve to go bad?
If the EGR valve fails to close, this may be caused by heavy deposits on the tappet or valve. The EGR may be damaged through overheating caused by incorrect control, high exhaust back pressure or non-opening blow-off valve.
How do you determine if the EGR valve is bad?
You’ll know if your EGR valve is stuck or malfunctioning because your car will experience symptoms like rough idle and bucking on acceleration. Fuel mileage will also suffer, and you may see a check engine light followed by a readable code in your car’s OBD-II or newer computer.
What is the function of the EGR solenoid?
The EGR solenoid regulates small amounts of exhaust gas.The EGR which means exhausts gas recirculation.

How is the EGR system controlled by the computer?
The EGR system is controlled by the EGR control solenoid. When the EGR control solenoid is activated, a passage is opened up that allows exhaust gases into the intake manifold. The EGR solenoid is controlled by the engine computer, and activated at very specific times in order to achieve…
When does the Check Engine light come on on an EGR?
Check Engine Light comes on. An illuminated Check Engine Light is another symptom of a bad or failing EGR control solenoid. If the computer detects an issue with the EGR solenoid, circuit, or system, it will set off the Check Engine Light to notify the driver of the issue.
