Pinpoint Test He: Exhaust Gas RECIRCULATION (EGR) Systems: Introduction: Notes
WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2006 Mercury Mountaineer, 2006 Mercury Monterey, 2006 Mercury Montego, 2006 Mercury Milan, and 2006 Mercury Mariner. However, it is still accessible from the selected car via links, so may be relevant.
This pinpoint test is intended to diagnose the following:
- differential pressure feedback EGR (DPFE) sensor (9J460)
- exhaust gas recirculation (EGR) valve (9D460) (9D475)
- EGR vacuum regulator (EVR) solenoid (9J459)
- orifice tube assembly (9D477)
- DPFE sensor pressure hoses
- vacuum lines
- harness circuits: VREF, DPFE, SIGRTN, EVR, VPWR
- powertrain control module (PCM) (12A650)
