Pulled Codes, Please Help
 

ok, ive got a sn95 5.0l mustang motor in my bronco 2, and i pulled codes.

what i came up with was these codes
KOEO
327-EGR valve position circuit below minimum voltage/(EVP/EPT) valve position circuit below minimum voltage
539-A/C on/defrost on during KOEO test(i dont have an ac pump on the motor anymore, what do i do?)
552-Air management circuit 1 failure/Thermactor air bypass solenoid circuit failute
553- Air management circuit 2 failure/thermactor air diverter solenoid circuit failure
563-High speed electro drive fan circuit fault(im running a mechanical fan)
558-EGR valve regulator solenoid circut failure
565- canister purge solenoid circuit failurte

from what i see they seem to all be solenoid problems, could i have the wrong relay box installed and that be some of the problems?

KOER
116-coolant temp higher or lower than expected
311- thermactor air systedm fault during engine run
327- same as KOER test

if anyone could help me out on what to do to fix them all, that would be much appreciated

:cheers:

it sounds like you may just want to change the whole EGR Assembly. A new valve an d solenoid is only going to run you about $75. If not just pull off the valve and clean it with some carb spray.

It's pretty simple, just unbolt it from the intake and spray some carb cleaner or some throttle body spray into it and dry to wipe it out with something like a q-tip. Just be sure to let it dry before you hook it back up. Also make sure you have the right temp. t-stat. That or your coolant temp sensor in the intake manifold may be bad, they are usually less than $15. Can you tell I work in a parts store....
