Egr Valve

[voz]

Hola.. yes i am new..and yes i tried the search feature!!

A little background.. I got this 00 expy new in 00 sold it to my bro-inlaw in 03 just flew up to NYC to get it saturday.. bro said check engine light was on ..so he took it to a shop in ny and they said it coded egr.. so the fella cleans the valve and the light goes out but comes back on in 2 days he takes it back... picks it up and light is off... kewl right!!

I take it to get state inspection today.. it coded egr again.. and check engine light does not work anymore...

QUESTIONS!!

could i try and get over by removing and cleaning all egr realted hoses, lines and hardware? I know that clogged hoses and lines will still code egr if egr is replaced and hoses are clogged or dirty..

or should my cheap ass just replace them?

I am not going to a stealersgip.. so which online source do you suggest?


Thank You!!

meed code to tell you what to do

what is a MEED Code?
It coded EGR failure

 

[JUST4FUN]

sorry i ment i need the code from the puter like p0401

10.4

I'll try and locate it!

changed egr and cleaned out those 2 rubber hosesand metal pipe that goes from egr to manifold.. and it still codes

i will try and buy the metel pipe and get new hoses!!..

I will also run some seafoam through it!!

 

[JUST4FUN]

with out the code your throwing money out the window

I know.. I know... but i could not get it... can somplace like autozone or advance auto hook up an obdII thingy and get me code?

here ya go.. I had it all along and did not know it..

I never said i was bright!!


P0401 - EGR Flow Insufficient Detected

That is probably the EGR flow sensor and not the EGR valve. Those things get gummed up with carbon after a while. Ford actually measures EGR flow and not just the EGR position.

Shit that Sensor is the most expensive part!

Tube is 65 at stealership and i believe sensor is over 100.00

i know i could prolly get cheaper on net, but i dont want to wait.. have to get it inspected b4 11/01/06


Sucks to be me!

 

[green03]

try cleaning the tubes with compressed air and gently clean out the sensor. Then clear the code and see if it comes back....

Is that what they call the PRESSURE SENSOR?

 

[green03]

it is a flow sensor that measures pressure drop across an orfice. I don't know what ford calls it but it has two small hose connections that hook up to the tube that brings the exhaust to the EGR valve.

Pics of said items..

Vacuum regulator control

Pressure sensor

got these part names from

Sorry for being a PITA.. but this shit has me pissed!


Is there an online source for looking at micro fische of this truck?

I know they have it for my motorcycle..

 

[green03]

hmmm not sure... see if autozone has it so you can touch it. The vacuum regulator is what opens and closes the valve. If i had to guess the pressure sensor is the flow sensor. Just try cleaning yours first.... maybe it would be free to fix!

ok..ok..went to look at truck...


sorta flat piece with a two wire plug on its right side and 2 rubber hoses on the left that connect to the tube from egr to manifold..

it is located just left of the egr valve



what is the one just left of the one above?

 

[green03]

the one you describe with the two hoses is the flow sensor.... send a picture if you want for the other's identity....

2 rubber small {maybe 1/4 inch inside diameter hoses,} that go from sensor to the metal tube that goes from egr to exhaust manifold
