    My 2000 Ford Taurus first would not start but when given a jump started right up. It needs a jump everytime to get it going. If you hook the cables up you don't even have to start the other cars enging it will crank right up. I smelled a light burning odor but could not find where it was coming from then the check engine light came on. I had a new starter put on April 30th. My friend took it to Autozone and they told him that the battery was fine but the cells were low in the Starter (what cells?) But they also said that it was showing a code 1401, but they could not read what that meant past 1000. Can you tell me what this might be?

You probably pulled a code p0401, insufficient egr flow. Your DPFE sensor is more than likely at fault. There has been a lot of trouble with these sensors. Then reset CEL or disconnect battery for 5 minutes.

- faulty EGR valve
- EGR valve stuck closed
- problems with the DPFE sensor (Ford)
- problems with hoses to the DPFE sensor (Ford)
- problem with the EGR vacuum switching valve (Toyota)

- vacuum supply issues at the vacuum-operated EGR valve

EGR FLOW INSUFFICIENT


On your EGR tube you have two hoses coming off of it. If you put them on in reverse you will get a code of insufficient flow. I put headers on and replaced EGR tube and valve and the flow sensor and that's the code that I received switched the hoses and solved the code

OBD-II Trouble Code P0401 - Insufficient EGR Flow

EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve, an actuator solenoid, and a differential pressure sensor EGR (DPFE). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0401 code means that OBD detected an insufficient amount of EGR. You may notice drivability problems such as pinging (a.k.a. pre-ignition knock) when the engine is under load or the vehicle is at higher speeds. There may also be other symptoms.

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

Check it and keep us updated. Hope this helps (remember to rating this free answer).

P0401....EGR flow insufficient detected. You can try removing the EGR valve and cleaning the carbon deposits with some carburetor cleaner.

Check Engine Light Just Came On..


Remove the EGR valve and clean it out. It's probably carboned up really bad constricting the exhaust flow. Also remove the EGR tubes and clean them out as well. I use brake cleaner and keep spraying the pieces out until it's pretty clean and re-assemble.

2002 accord code P0401 [egr insufficient flow detected]


the code you have may not be due to insufficient lift, more likely you have either high or low voltage running through egr. replace the valve and your issues should go away.
