2000 GC CEL on code 1494

hi guys, been a long time since ive been on the forum. My girlfriend just picked up a 2000 grand cherokee 4.0 with 96k on it awd with a moonroof and all the original factory and dealer optional floor mats for 4900. The check engine light is on and when i pulled the code I got "P1494 (M) Leak Detection Pump Sw or Mechanical Incorrect input state detected for the Leak Detection
Fault Pump (LDP) pressure switch ".
Anyone know what i can do to fix it. The PO had an invoice from the dealer basically stating they couldnt find anything wrong and wernt sure what it could be.
thanks for any and all help
andy
