Eobd code 4010 insufficient flow to egr valve on 2001 ford maveri
Hi got a ford maverick 2001 2.0l 16 v petrol uk spec, i have changed the egr valve and the egr solenoid have also removed all vaacum hoses to do with egr and checked for blocks and leaks also re moved metal tube from ex manifold to egr checked for blocks, if i leave solenoid elec connection disconnected car runs ok but light comes on was thinking of changing dpfe valve but it is expensive and i need to know it,s gonna work before i,ll pay out for it .
any help would be great

Re: eobd code 4010 insufficient flow to egr valve on 2001...
Dpbeffe sensors on fords are a common problem I had the same issue with several fords of same year new sensor from ford only cost me 38$ from ford just make sure both tubes to dpfe are clear though any blockage screws up the reading from the sensor
a 6ya expert can help you resolve that issue over the phone in a minute or two.

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
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).
insufficient egr flow usually the dpfe sensor located in the back of intake manifold or mounted on firewall.if you follow the wires/vacuum line from the egr valve you'll see it. common problem & fairly easy job pick up a new 1 so you no what it looks like
P0401 shows an Exhaust Gas Recirculation Flow Insufficient. Without a good scan-tool you will be playing the "Parts Changing Game". Insufficient flow can be the result of a vacuum leak, bad MAP sensor, an exhaust leak, faulty EBP sensor, carbon build-up, and so on. I wish I could say more but with all the electronics it is more complicated then earlier cars.
It is the DPFE sensor with out this your rpms will continue surge. Alot of people make the mistake of just replacing the EGR valve instead of the DPFE sensor which measures exhaust prssure going through the EGR vavle.
The DPFE (Diferential Pressure Sensor)sensor is usually mounted on the engine and is connected to the pipe that runs from the exhaust manifold to the EGR valve with two rubber hoses. When the sensor goes bad, the Check Engine light comes on and typically sets any or all of teh following fault codes: P0171 & P0174 (lean codes), and/or P0401 (insufficient EGR flow). Nine out of ten times, the fault is not a bad EGR valve or a vacuum leak, but a bad DPFE sensor. A replacement costs about $112 at Ford, or about $48 at an aftermarket auto parts store.I hope this helps.
