    Q:
    How to replace the EGR Tube and EGR Valve on 1993-2011 Ford Ranger? Posted by Customer
    A:
    The EGR system reduces NOx emissions by recirculating exhaust gases into the intake manifold, lowering combustion temperature. To replace the EGR valve, disconnect the battery cable, remove the air cleaner outlet tube, vacuum hose, and exhaust manifold tube. Unbolt the valve, replace the gasket, and clean the manifold surfaces before reinstalling. For EGR tube replacement, remove the valve, disconnect fittings, remove and reinstall the tube. To replace the EGR Vacuum Regulator Solenoid or Differential Pressure Feedback Sensor, disconnect the battery, detach retainers, disconnect connections, remove bolts, and reinstall in reverse. Note: 2002 and later 3.0L engines do not have EGR valves.

    Q:
    How can checks be performed on the EGR valve and EGR control system for the 2001 Ford Expedition? Posted by Customer
    A:
    The EGR valve is controlled by an EVR (EGR Vacuum Regulator) and the PCM. Its operation can be tested using a vacuum pump. The EGR control system relies on sensors like the ECT (Engine Coolant Temperature), TPS (Throttle Position Sensor), MAF (Mass Airflow Sensor), and TCC (Torque Converter Clutch) to determine the correct ON time for the EGR.
