Service soon codes

[Shelby1]

Hi all,
I have had the decision message come up on the car, it was on for a few days and then disappeared for a few weeks.
its come back on again today and has the following codes
P2084
P03B7
has anyone any ideas on what the issue could be. I have googled the codes and it looks as though is a gas sensor?
any help or advice would be greatly appreciated?

thanks

P03B7 is that cylinder number 2 pressure sensor circuit erratic ? The reason I as is that the photo is missing the rest of the code descriptor .
but it probably means there's carbon deposits on the pressure sensor tip .coukd try taking the plug out and cleaning the tip of it .
P2084 exhaust gas temperature sensor.is this bank 1 sensor 1 or bank 1 sensor 2 .?
But that's leaning towards either a faulty sensor or its wiring which you have to assertain .

Thanks for the reply lizard. I have tried adding an attachment which shows the whole code. Would you have any idea how and where I would start to look at checking the pressure sensor tip that you have suggested

Take out the glow plug for that cylinder and clean it
Cylinder number 4
