6.4L DPF / Exhaust Sensors
When running DPF PRESENT tuning, it is required that all sensors
located in the exhaust system stay in place and plugged in,
otherwise you may experience a Check Engine Light (CEL) and
even a loss of power (limp mode).
When running
DPF REMOVED tuning, it is recommended that all sensors located
in the factory exhaust system be unplugged from the electrical
harnesses. These sensors can also be removed completely with
the factory exhaust if desired. On the 6.4L Powerstroke, there
are usually 2 EGT Sensors and 1 Pressure Sensor.
Note: The vehicle will not run with sensors removed
unless DPF REMOVED tuning is installed.
