DPFE sensor - anyone heard of this IN
an Isuzu engine?
Dreaded CEL is back on, but the truck is actually smoother then when the CEL is off - this is getting extremely irritating.
Same code P0401, I'm sure everyone knows by now that I've replaced the EGR valve, cleaned those pipes a million times, cleaned the TB, reset the computer so much that the bolt on the negative battery needed replaced last time.
Per Tynan's Isuzu in Denver, the Isuzu engine does not have a DPFE sensor, but I've heard rumors that this 3.2L *may* in fact have one. And also, if it does have one, where can I find it, dealership, Napa, and autopartswarehouse (internet) doesn't carry one for Isuzu engines.
Also does anyone know what else could be linked to the EGR insufficient flow reading? Any other sensors, i.e idle air control, temp sensor, etc.
I know the MAP sensor *could* be related, but I've also heard that it would throw it's own code.
FWIW - all wiring connections are reading fine.
