What does code 1406 mean?

This is a problem in the EGR or EGR control solemoid. It is indicating the EGR valve is not in the proper position. It can be a stuck egr valve or lack of proper Egr vacuum pressure to position the valve.

How to clean an egr

Remove the air cleaner outlet tube. Detach the EGR tube (Fig. 1). Disconnect the EGR vacuum tube. Remove the EGR valve (Fig. 2). Remove and discard the EGR valve gasket. To aid instillation, loosen the EGR tube bolts at the exhaust manifold. Install a new EGR valve and gasket.

Code po401

A code P0401 most likely means one or more of the following has happened:
  • The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
  • There is a blockage in the EGR (tube), most likely carbon buildup
  • The EGR valve is faulty
  • The EGR valve may not be opening due to a lack of vaccuum
Possible SolutionsIn fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.
  • Use a vacuum pump and pull the EGR valve open while monitoring engine RPM'sicon1.png & DPFE voltage. There should be a noticable difference in RPM's with the EGR open
  • Clean out the EGR valve and/or tubing to remove deposits
  • Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)
  • Replace the DPFE sensor (with a good quality / OEM one)
  • Replace the EGR valve

you did not post what model of Linclon, but in any case the PO 0171 is fuel system to lean on bank 1.

look for a vacuum leak if no leak then you will need to test the fuel system, there are many idems that could set this code ( injector, vacuum leak, EGR valve, TPS sensor, ect.....) there is a test for the code but you will need to have a scanner to run the test, A SCANNER NOT A CODE READER. if you would like the test i will send it to you but it is many pages.

None of my power door locks are activating (opening or closing) on my 2005 Linclon Navigator, what do you think could be wrong?

Try checking the fuse box for the door lock fuse fault and replace with DESIGNATED fuses, the right fuse will be shown on the cover of fuse box.
