Pinpoint Tests C: Crankcase Ventilation Sensor: Introduction
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2017 Ford Transit-350 HD, 2017 Ford Transit-350, 2017 Ford Transit-250, 2017 Ford Transit-150, and 2017 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: CRNKCSVT, GND, SIGRTN, VBPWR and VPWR
- crankcase ventilation sensor
- crankcase ventilation heater
- PCM (12A650)
