P1401 - DM-TL air pump motor current draw is higher or lower than expected (normal = 17-36 mA).

This is an electrical issue with the pump, it's not related to a leak in the evaporative emission control system.

What do code 1401 mean for my 2001 Ford crown Victoria police intercepted ?


2001 crown vic, code # po1401. this code has to do with the egr system, the first thing is to check the dpf sensor, this sensor tells computer that the egr valve is working, there are two hoses the run off sensor and go into exhaust lines, check the hoses ,make sure they are on and not split, if hoses are good then start by replacing that sensor. here is a pic of it.and also the hoses86ba1833-6384-4844-833d-84eadda90752.jpg1944c06a-cc52-4fd8-9c4f-ae244e7ad0df.jpg

My check engine light came on ,so i took it to get it put on the computer and the code was 4101.Im trying to find the discription and where is it located 4101


I didnt find a 4101 however I did find a 1401. If you think it might be 1401 this is an evap code and you may end up taking it to the shop for a smoke test to find the leak. Make sure that your gas cap is tight. A loose gas cap will also throw the 1401 code since the system will not have the right pressure.
Hope this helps... Dale

Replaced plugs and wires 2002 ford explorer idles good even in drive or reverese tranmission sputters while driving at low rpms or in overdrive po code 1401 has been on since 42k now 108k


code 1401 means your dpfe or delta pressure feedback to your egr valve is defective and needs to be replaced. I would suggest you clean or replace your egr valve as well with throttle body cleaner. A defective dpfe can cause your vehicle to run lean and when near failure is certain, it will cause your vehicle to stumble.
