ACTION:
Use the following revised DPFE sensor voltage ranges for all (black plastic or aluminum) DPFE system applications when checking the PID (Parameter Identifier Display) value "DPFEGR" or when measuring the DPFE sensor input directly at the breakout box. Refer to Figure 1.

NOTE:
THESE LISTED VOLTAGE RANGES SHOULD BE USED FOR ALL (BLACK PLASTIC OR ALUMINUM) DPFE SYSTEM APPLICATIONS WHENEVER CHECKING THE PID VALUE "DPFEGR" OR WHEN MEASURING THE DPFE SENSOR INPUT DIRECTLY AT THE BREAKOUT BOX.
