Pinpoint Tests RC: Exhaust Gas Temperature (EGT) Sensor: Introduction
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2019 Ford Transit-350 HD, 2019 Ford Transit-350, 2019 Ford Transit-250, 2019 Ford Transit-150, and 2019 Ford F-550 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Manual regeneration of the diesel particulate filter causes the exhaust gas to get very hot quickly. Initiate a manual regeneration only when the vehicle is on the ground with the area around the tailpipe free of people, obstructions, foreign material or other items. Failure to follow these instructions may result in serious personal injury.
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:
- EGT sensor (5J213)
- harness circuits: EGT11, EGT12, EGT13, EGT14, and SIGRTN
- PCM (12A650)
