2002 Ford Explorer -- P1400 code (DPFE sensor) - Ford Forums

fordtuff · 07-01-2007, 12:14

My '02 Explorer with a 4.0L engine posted a P1400 code at 83K miles. From poking around this forum, I understand that I probably need a DPFE sensor.

I've read about a dozen times they are easy to change and it can be done in under 5 minutes... the problem is I'm not a mechanic and I don't where to locate the sensor.

Can anybody describe to me where to find it? Or if you are really feeling generous, can somebody post a digital pic of where it is located?

Also, once I change the sensor... will the "Service Engine Soon" light turn off or do I have to pay somebody to clear the code?

Thanks!

The DPFE sensor is usually not hard to change. There are 2 small rubber hoses that run from the EGR tube to it.

Thank you!

Now that I've changed the DPFE sensor, are there any "home remedy" solutions to turning off the "Service Engine Soon" light?

Will disconnecting the battery work? Unfortunately, I don't know anybody with an ODB scanner.

Thanks!

Hi
Disconnecting the battery works sometimes, but you'll have to leave it for long periods of time. Also, after a number of drive cycles (that I can't remember exactly) if the PCM doesn't see a problem with the DPFE it will turn the light off on its own. Other than that...scanner. cheers

Good advice on changing DPFE sensor. Changed EGR valve, then engine light came on. Changed DPFE sensor and reset the engine light. Have run my 2002 Explorer for more than a few miles and light stayed off. Hopefully this fixed this issue. Thanks for the info.
