When do you need to replace a Ford EGR valve?
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. A bad sensor will illuminate the check engine light and trigger any of the following fault codes: P0171, P0174 and P0401.
What is the fault code for Ford EGR?
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. This unit is far more likely to fail than your EGR valve.
Where is the EGR valve on a 2005 Dakota?
On a 2005 Dakota with 4.7 liter engine (non-HO), the EGR valve is located near the intake manifold on the driver’s side right up against the firewall. It’s hard to spot as it sits lower than the intake manifold. To change it, remove the electrical connector.
Where is the EGR valve on the exhaust manifold?
Install the EGR valve tube into the connector on the exhaust manifold. Torque the line nut to 26-33 ft lb (35-45 Nm), while holding the connector with a wrench to avoid damage to the tube. Lower vehicle. Tighten the EGR valve line nut at the EGR valve, and torque to 26-33 ft lb (35-45 Nm).

What causes a leak in the EGR valve?
The differential pressure sensor (DPFE) monitors the EGR flow and reports to your EGR modulator, which controls your vacuum solenoid. EGR valves contain a spring-actuated diaphragm. 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.
Which is part of the EGR system does it control?
Your EGR system is comprised of several components. The EGR valve controls the flow of exhaust gas into your intake manifold. The EGR vacuum solenoid (EGR SV) controls the flow of engine vacuum.
