I had a engine light on, pulled codes and got 332. Checked egr valve it moves and holds vacuum. Replaced EVR no help. Replaced EVP no change. Got to checking and found green lineto the egr was broke, replaced with rubber one still code 332. I am getting plenty vacuum from the white line but none on the green one going to the evr? Even drove down the road still no vacuum to the egr. Checked the power to the evr probing both the red and black wires going to the evr i got 12v koeo and 14.5 koer and it never changes through any rpm range????? Any one know the problem im freaking clueless!!!!

I have to roll very soon so here are some checks;

EVR Overview & Test, EGR Vacuum Regulator (EVR)

"...EVR Testing: vacuum should vent from the green line on a good valve NOT energized. When energized, vacuum should hold from the black to the green. Resistance across the terminals should be 20-70 ohms..."

DTC 332; "...indicates the EGR valve did not open with the engine stabilized and the EVR solenoid duty cycle present sometime during vehicle operation. Possible causes: "...Obstructed or cracked hose to EGR valve, Icing, Damaged EGR valve, Damaged EVR solenoid harness..."

DTC 332, P1407 and P1408 or detonation; "...We have run into many situations where a code for insufficient flow has been set and the system is functioning correctly. Then it is time to check the EGR passages. There is a Ford Technical Service Bulletin (TSB 96-23-4) that addresses this for some vehicles. This TSB includes: 1992-1995 Crown Victoria 1994-1995 Thunderbird 1991-1995 Town Car 1992-1995 Grand Marquis 1994-1995 Cougar The concerns have to do with intermittent MILs; DTCs 332, P1407 and P1408; or detonation. If exercising the EGR valve does not result in a change in rpm, then the passages may be clogged. There are “U” shaped passages (Fig. 6) under the throttle body adapter that get clogged with carbon. Remove the adapter, clean the passages and reinstall with a new gasket. Just because the vehicle you are working on is not listed in the TSB doesn’t mean you may not have a clogging problem. Make sure you check the passages and be sure they are clean. Just a slight restriction can cause a flow code to be set, and you may still have an rpm drop that can mislead you..."

DTC 332, P1407, and/or P1408: TSB 96-23-4 detonation Caused by buildup in the Exhaust Gas Re-circulation (EGR) groove of the intake manifold (throttle body base)...basically you have to take the throttle body off, clean out the passages and put it back together with new more & view depiction
