Just pulled some codes from my stang and...

...need some help fellas. I pulled three codes.


332 - EGR valve opening not detected: Does this mean that my EGR is shot and should just get rid of it and find a replacement. Ive looked into getting rid of the EGR completely before but ive heard that it could raise temps in the combustion chamber...anyone have any thoughts on this? A new EGR is a little over 100 bucks which sucks. I just removed my smog pump so if I could just get rid of the EGR for a few bucks to finish cleaning up my engine bay that would be great.

542 - Fuel pump circuit failure: What does this mean??? My fuel pump still works obviously because I have been driving my car around. (this one im thinking might be coming up because when I changed my fuel filter two days ago I unpluged the wires that run the pump so i could turn the car over and release the pressure. I tried starting the car without plugging it back in once i was done so im thinking the car thinks it went bad. hoping it will fix it self and drop the code.)

564 - Electro-Drive Fan circuit failure: Ive come to find out that my fan isnt kicking on at its low speed temp. It only kicks on when the car gets really hot. Is this due to a bad relay???

thanks fellas. ill check em out. Should I just get rid of my EGR?? I dont have emissions testing and im in the process of cleaning up my engine bay. I think it would be cheaper to just rip it out.

The EGR and Smog system are unrelated.

If you don't mind chancing having pinging at cruise, go ahead and delete it.

The likely cause of the EGR code is a bad vac line to the EGR valve or EGR solenoid (so there's nothing to actuate the EGR), a bad EGR solenoid, or a bad (or unplugged) EGR position sensor.

For the fan, first see if CCRM pin 14 shows 12 V when you're at 212* or hotter (without the AC on).

Thanks alot for the info. If I do decide to delete the EGR should I just drop my timing back down? I either have it set to 12* or 14* right now I dont remember.

If it is not showing 12 v then what should I do??
