96 jaguar vanden plas p1185 p1186 p1188

Hello everyone. I own a 1996 Jaguar Vanden Plas. My check engine light has come on recently and I need any help anybody has to offer. I had a buddy of mine hook up the car to his obd-II computer thing and it spits out three codes. using this site(which was a huge help) I found out what those codes mean...kind of. It spits out codes: 1) P1185: FTS High - Fuel Pump Temperature Sensor High 2) P1186: FTS Low - Fuel Pump Temperature Sensor Low and 3) P1188: Calibration Memory Fault. )Ok so I am assuming that the three codes are related in some way, most likely the Fuel Pump Temperature Sensor. So what do I do? Does his mean that I just have to get a sensor replaced? do I have to get the fuel pump replaced? Do I need to take it to a jaguar dealership to get it worked on? Please any ideas would help. Thank you for your time and I look forward to any replies you can offer.
