DTC Scanner Definitions

Can anyone direct me to where I can find DTC Code Definitions for my 1997 Land Rover Range Rover 4.0? I get 4 trouble readings of (2) P1193 and (2) P3999. Cannot find these codes anywhere. Any help regarding the codes or otherwise would be greatly appreciated.
Happy Holidays everyone!:)

It looks like P1193 is the Oxygen Sensors. Are there 2 or 4 and does anyone know where they are located? Thanks again.

RE: DTC Scanner Definitions

Your 1193 is for 02 sensor heater circuit open down stream.
The other code I don't see.
How many miles on the truck and how is it running?

RE: DTC Scanner Definitions

It's got 148k miles and runs great. MPG 13-15. This is the oxygen sensors correct? I assume I would have to replace all 4 since I don't know which are faulty. What does this mean, "02 sensor heater circuit open down stream"?
