96 VDP. check engine light codes P1185 P1186 and P1188

Hello everybody. This is my first post. I recently bought a 1996 Vanden Plas. I love this car. It runs a heck of a lot better than my 95 sable ever dreamt of running. that aside...recently my check engine light has come on. So I had a friend hook it up to his OBD computer thingy. It threw out three different codes. P1185, P1186, and P1188. So I looked up what these codes mean. P1185 O2 Sensor Heater Circuit Open - Hardware Fault P1186 O2 Sensor Heater Circuit Shorted- Hardware Fault
P1188 O2 Sensor Heater Circuit Resistance.

So...now what? I am assuming that the o2 sensor has gone bad? do I have more than one? If yes which do I replace? How do I find out which to replace? Where the heck are they? Any help would be greatly appreciated. I look forward to any help that anyone can give me.

In the US, you have 4. Two per Bank, fore and aft of the catslytic converter, two banks. They are the heated type and you fault says thatthe heater is not working. I would check the wiring connections, then the sensors. The heater circuits can be tested with an ohmmeter without too much risk of damagie.
