Ford focus 2008 egr valve 1.6 diesel

SOURCE: 1997 ford explorer check engine lite is on.Code

you probably have blocked passages in the intake manifold. remove the egr and check the port for a clog. you can scrape most of the carbon out with a pick or screw driver and then use some spray carbon cleaner in there. also check the metal exhaust line to the egr

Testimonial: "i looked at what was discribed and that wasnt it.Good thought thouh"

SOURCE: egr valve insufficient flow detected

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.

SOURCE: 2002 ford focus p0401

Here is a list of possible causes for a PO401, hope this helps.

• DPFE sensor signal circuit is shorted to ground
• DPFE sensor VREF circuit is open between sensor and PCM
• DPFE sensor downstream hose off or plugged
• DPFE sensor hoses both off, loose or damaged
• DPFE sensor hoses connected wrong (reversed)
• EGR orifice tube is damaged or restricted
• PCM has failed

Remove the throttle body housing on the top of the intake, it is a 90 degree tunnel like small piece held by 4 small bolts, turn it over and look for two holes, these holes are for the EGR valve flow, they are probably plugged up with carboned crud, clean them out with the tip of a screwdriver if neccessary to remove all the crud, once its clean reinstall it and reset your check engine light, hope this helps, let me know

SOURCE: EGR VALVE ON 96 FORD PROBE SE

If it's a 2.0L, 5 speed (1994-7) there are two DPFE solenoids (both w/ 3 vacuum ports) near the oil filter, which control the EGR valve. They are discontinued and impossible to find except on junked cars. (FORD #'s K5T44093-4)
I have to junk my 1996 Probe if I don't find them - Missouri emissions.
