Pinpoint Tests W: Exhaust Gas RECIRCULATION (EGR) System: Introduction
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2018 Ford Transit-350 HD, 2018 Ford Transit-350, 2018 Ford Transit-250, 2018 Ford Transit-150, and 2018 Ford F-550 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.
This pinpoint test is intended to diagnose the following:
- harness circuits: VREF, EGRVCH, EGRVCL, EGR and SIGRTN
- EGR valve (9D475)
- PCM (12A650)
