ISSUE
Some vehicles may exhibit a malfunction indicator lamp (MIL) "ON" with or without the following symptoms: Rough Running, Lack of Power, Surge or
Poor Fuel Economy, along with diagnostic trouble codes (DTC's) P0401, P0402, P1400 or P1401. This may be caused by an intermittently functioning
tube-mounted delta pressure feedback EGR (DPFE) sensor (Figure 1).
ACTION
For vehicles equipped with a tube-mounted DPFE sensor, perform the following diagnostic procedure and repair action. This procedure supersedes the
diagnostic procedure in the PC/ED Manual for the issue described above.
