Pinpoint Tests KD: Electric Exhaust Gas RECIRCULATION (EGR): Introduction
WARNING: This page does not describe the selected car, but rather 27 other vehicles, including the 2021 Lincoln Navigator, 2021 Lincoln Nautilus, 2021 Lincoln Corsair, 2021 Lincoln Aviator, and 2021 Ford Transit-350 HD. However, it is still accessible from the selected car via links, so may be relevant.
This pinpoint test is intended to diagnose the following:
- electric EGR stepper motor (9D475)
- harness circuits: EGRMC1, EGRMC2, EGRMC3, EGRMC4, EGRVCH, EGRVCL, EGRVP, SIGRTN, VPWR and VREF
- PCM (12A650)
