Exhaust Sensor Issue with Ford F-Super Duty
Some 2008-2010 Ford F-Super Duty trucks equipped with a 6.4L diesel engine and built on or before Nov. 1, 2009, may exhibit a diagnostic trouble code (DTC) P040D related to the exhaust gas recirculation temperature (EGRT) sensor located in the right-hand turbocharger inlet pipe.
1. Using a scan tool, verify the DTC.
2. Turn the ignition switch to the off position.
3. Remove the right-hand fender splash shield.
4. Disconnect the glow plug module electrical connectors.
5. Disconnect the inlet EGRT sensor electrical connector.
6. Cut the wire just above the sensor.
