Codes 22,32,53 Where to look?

I finnally got around to checking my Engine lights and i got 3 codes.

22- Low Voltage at TPS -OR- Fuel Cutoff Relay Circuit open/shorted

32- Fault in BPS circuit -OR- Fauilt in Exhast gas recirculation valve -OR- Fault in Vacume Regulator Valve.

53- High Voltage at battery -OR- High Voltage at exhaust gas recirculation valve -OR- Voltage Reference Error -OR- Anti-theft prob

For Code 22 i checked the voltages and they are just about perfect (.48 at idle, and 4.8 at WOT). So that leaves me w/ The "Fuel Cutoff Relay Circuit" - Wich i can't find in either of my books (chiltons or haines). Can somone help direct me where to look?

For Codes 32 AND 53 they both say somthing about an error w/ "Exhaust Gas Recirculation Valve" - Can't find that in my book either. So Some help on that too would be apreiciated.

-I have scoured my books... and can't find anything related to these. so, Thanks for any help!!!

My rule of thumb on multiple codes: Unplug and inspect connections from ECM to sensors. ALL connections. Usually just unplugging and reseating connections corrects erroneous codes. But of course it could be multiple failures. YMMV

Code 32 is in most cases a stuck EGR valve. You can run a vacuum check on it to see if it is still good.

Yup, and did you reset the codes, to see if they come back? Sometimes a code can just be an intermittent code set and stored. How is the car running?
