My check engine lights keeps coming back on. I replaced the EGR valve & sensor. I was told by a local parts guy that the problem is the EGR tube connecting to the manifold. He says that they usually get clogged up triggering the EGR systems failure "check Engine"
Has anyomne seen or heard of this before and does anyone have any advice on how to get the tube out? they screw on both ends but the bottom end is in a real hard position. Is ther a recommended tool to use?

Take the top loose and start it for a very short time. If exhaust comes out, it's not plugged. What is the code you're getting?

Code P0401
Insufficient flow detected

I did pull off the top of the tube and there was exhaust flow. Not sure where to go from here. I will attempt to get the tube disconnected at the base to clean it out...

Not sure if this might apply / help .


PO401 code means that:
The PCM has determined that there is insufficient flow in the exhaust gas recirculation system. Definition: EGR system fault (Exhaust Gas Recirculation) Probable Causes: a. Blocked passage on EGR system b. Failed EGR Valve c. EGR solenoid faulty d. Failed EGR pressure sensor where applicable e. Failed EGR position sensor where applicable

The EGR valve isn't getting the vaccum required to operate the valve. Check engine light is on.

do you have a code for egr? if you do follow the hose all the way to the egr solenoid and make sure the other hose attached to the solenoid has vacuum, the egr only gets vacuum when the computer triggers it but not all the time .
