Re: How clean Taurus EGR?
I'll have to agree with Happy Traveller.... the DPFE is, by far, the most
common cuase of this particular code (I'm guessing P0401....). Please,
folks, try to realize that OBD2 is NOT cut and dried. All codes require some
form of diagnostics to ensure that we aren't going to replace parts
In your case, the PCM is seeing "low or insufficient EGR flow". You are
expecting the PCM to be telling the truth. While the PCM thinks it's telling
the truth, it is more likely that the DPFE sensor is lying to the PCM and
the PCM will, in it's own turn, lie to you.
