CEL on having trouble self diagnosing

[Rakith]

My car is an EP3 05 facelift model

Twice in heavy rain I've had my CEL come on, the CEL would be gone the next day.

I tried to self diagnose with a cheap OBD2 port reader using the Torque app for Android which would not connect to the car so I couldn't pull the code, i then went on to the paper clip method explained in the sticky here but I have no wire going into terminal 9 of my OBD2 DLC.

Is this normal or am I doing something wrong?

Kind regards
Rakith

Also the OBD2 scanner does power up when connected with the ep3, I've also tested the scanner in a Citroen Saxo and it connected to the car and checked for faults

Potentially an O2 sensor picking up moisture/dirt in the rain??

I am hoping so , got a few more people with obd2's that I'm going to visit and see if I can get a connection to the car so I can grab a code.
