Erase the code and see if it returns. If it does, replace the valve. What engine do you have? If it is a 3.4 it should be right on top. One plug and two bolts.

You need to diagnose the EGR System
Not replace parts in hope of getting it right
Codes only indicate an Emissions Malfunction
or Fault, thus the code
Codes & trouble charts are used to then component test
Google the code & study the problem
There are many EGR Codes--- study yours ,as it pertains
to your vehicle & engine package

    2005 Chevrolet Equinox These are the codes that show up when we place the Scanner P0068, P0108, P0300, P0405, P0443 Can someone please help me with this? Thanks in advance.


    P0108....Manifold Absolute Pressure/Barometric Pressure Circuit High Input


    P0300....Random/Multiple Cylinder Misfire Detected


    P0400....Exhaust Gas Recirculation Flow


    P0433....Heated Catalyst Efficiency Below Threshold (Bank 2)

    Do not have a listing for the 0068 reading as it doesnt exist in my list ,looking at this i would block off the EGR valve with a nice home made coca cola can gasket and this should cure your problems

    2005 equinox with P0405 code.


    Do you have an odd smell in the interior compartment? This could be due to the egr being damaged from debris from the road. Hire a professional to do it or go to a car parts store and get the motors repair manual or similar.
