P0118 is the diagnostic trouble code for low coolant, the other one is the DTC for an ECU failure or error.
Google the codes next time buddy. You probably need to go to Nissan for a diagnostic on the ECU code, where is your coolant going? Leaking on the ground, consumed by the engine?
If you have basic machanical skills you can start troubleshooting the grounds, the ECU one is behind the air conditioner controller.

no there’s no coolant leaks, I’m thinking it’s a bad coolant sensor which is causing that, also would i be able to just buy another ecu and just replace it ? Or would there have to be some reprogramming?

Ok if the coolant isn't leaking out then WHERE IS IT GOING ? Do you have a blown head gasket and it's being consumed by the engine? Coolant levels don't just drop for no reason.
It's possible the P0605 code is being sent simply because the ECU is forced into fail-safe mode because it cannot read the temperature of the engine. P0118 can be a failed temp sensor, broken wire, broken harness.

Ok I gotcha the actual coolant level isn't what drops is the GAUGE reading that drops. Yes that is probably just the sensor itself and NOT the wiring or harness since it does send a proper signal for a short while and then just intermittently fails.
Replace the sensor, it's probably going to fix BOTH of your DTC errors.
