Tip & How-To about Ford F

EGR (exhaust gas recirculation) obd II code

Most of the time when the EGR vavle code causes the "check engine" light to come on, it's not the valve itself, but instead, it's the pipe going to the valve.This pipe gets clogged with carbon build up, and even the valve itself, gets clogged.To save a lot of money, try this instead of buying a new valve.Find the valve (usually at the top of the motor and there is a diagram under the hood showing where it's at) it's a round valve with two bolts holding it in place and some wires on top of it GM models and a vacuum line on Ford models,but i've seen it with a vacuum line on top of it on a lot of imports too.but on all models, there is a pipe at the bottom, and this pipe is usually the culprit.Just take a wrench and take the nut holding holding the pipe to the valve off, then remove the two bolts holding the valve on.take carburetor cleaner and spray the pipe very liberally.Now, while the valve is off spray the bottom of the EGR valve.Then take a small wire brush and scrub the pipe and valve.Reassemble , putting the valve back on the pipe and putting the bolts back on.Be sure to put the vacuum hose or the wired plug-in back on the valve.To reset the "check engine" light,(because it won't go off until it's reset), simply unplug the positive battery cable from the battery, and leave off for about five to ten minutes, then plug it back up, and see if that will help.This could save you at least $150. I hope it helps.

2005 magnum p0406 egr valve sensor code error

P0406 indicates high voltage on the EGR sensor circuit. this is recommended for every 30,000 miles be inspected. although EGR system do not requires periodic inspection. instead, check only if engine trouble's develop. most EGR's requires replacing EGR valve, cleaning passages and installing new vacuum hose. misrouted vacuum hose causes engine poor operation. so. not just to unplug it.

i got a p0401 code and i replaced the vavle and had my computer reset and the check enigne light went off but it came back on so i got a new vavle and it did it again so what else could it be

The pipe going from your EGR to the exhaust is probably clogged, try to spray some carb leaner into it to clear it (do not do to hot engine), you can also try a long pipe cleaner, also check where the EGR bolts on for carbon build up.

2005 grand caravan error code P0400 egr valve chk/ performance

I have the 2005 Town & Country TOURING . If my memeory serves me correct, I believe this was the same code that I got on time. The van didn't seem to drive any different but this is what I did and I haven't seen the light come on since.
first I went to the dealer ( you can get these parts from a auto parts house also) and bought the 3 gaskets total.for the the EGR solenoid vavle assembly where it bolts on to the engine ( that gasket was made from metal), NOTICE AN INDENTATION IN THE METAL GASKET WHEN YOU TAKE IT OFF,YOU WILL WANT TO PLACE THE NEW GASKET IN THE SAME DIRECTION. one gasket that goes between the EGR valve solenoid and the small stand pipe. and another gasket that goes between the stand pipe and where it connects to the plastic valve intake area cover on top of the engine.
I took the EGR solenoid off from the engine and took it apart (reall carefully) and cleaned it thouroughly with a spray carbuerator cleaner. I took mine "completely apart" after I did this I dont recommend to do this again, you can damage the coil inside if you're not cafefully. I suggest just cleaning the valve and plunger ports, etc....
When it was completely dry I reinstalled the EGR solenoid on the van making sure I used ALL NEW GASKETS. The van hasn't produced the engine light since. I hope this helps.

check engine light

yes you will have to hook it to a scan tool and erase the dtc or the light will stay on. sometimes you can unhook the battery for 30 sec or pull a fuse or turn the key on and off a couple of times
