  Q: What is the purpose and location of the EGR valve for the Honda Passport?

  A: The EGR valve is often causing emissions system problems due to corrosion or sticking, which is situated on the intake manifold. A simple test can be done by pressing the diaphragm of the valve under pressure while the engine is cool to ensure free movement. This cannot be used with electronic EGR valves on 1997 and later models. If the diaphragm does not move freely, then replace the EGR valve.

  Q: How to replace the EGR Valve on Honda Passport?

  A: The EGR system is used to lower NOx emission levels. Early EGR systems are equipped with either a Thermal Vacuum Valve or an Electronic Vacuum Regulator Valve. To check the EGA system operation, bring the engine up to operating temperature and allow it to idle for 70 seconds. To replace the EGR valve, begin by disconnecting the cable from the negative terminal of the battery. Remove the air cleaner housing assembly, detach the vacuum line, lift the vehicle, and support it firmly on jackstands. Remove the EGR pipe from the exhaust manifold, remove the mounting bolts, and clean the mounting surface of the EGR valve. Install a new gasket and the EGR valve and tighten the bolts securely. Connect the electrical connector onto the EGA valve and disconnect the electrical connector from the EGR gas temperature sensor.
