P1401 DPFE Sensor??
#46
Thanks for the input, and I'll look over the wiring once more. Hope it's just a loose connection. If I have to spend any more money to get the idiot light to turn off, I'm taking apart the instrument panel and removing the bulb. ;^)

I checked my wiring and connection and it's fine.

The 1401 code IS the result of a monitor test failure.
The code is an electrical feed failure called a circuit high. It's part of the code description.
Nothing to test for but find the cause.
You really do not want to just let the CEL light on or cover it over for this fault because then you cannot see other failures in the system unless you check for codes with a Scanner, now and then.
Good luck.

bd,
your posting in the wrong forum for a 2007 vehicle.
The 401 code is a test failure found by the computer.
The test is done two times for each drive cycle.
The failure is low flow rate through the system.
It can be a carbon blocked intake port after the EGR valve or the DPFE has failed and cannot report the test results.
A vacuum hose attached to the EGR may be leaking and unable to open the EGR.
The EGR seldom ever fails.
You can see the code does not tell what part is faulty.
Only the test that failed.
Good luck.
