Lafesta Overheating and Coolant Leak

Hi. I'm having a weird issue with my 2012 Nissan Lafesta with a gasoline engine. The engine overheats, the check engine light is on, and there's coolant leaking. My mileage is 119715 km. I suspect excessive pressure in the cooling system is the culprit. Could this be a control unit communication error?

Sounds familiar. I've had similar issues with my Lafesta. Could be a communication fault. Did you check the cable connections?

Where exactly should I check the cable connections? Is it easy to access?

It's likely the cable or plug connection of the component is defective. To be honest, it's a bit fiddly, and you might want to get it checked at a workshop. I ended up paying 95€ for the repair.

Thanks for the advice! I took it to a workshop, and it was indeed a defective connection, as you suspected. It's all fixed now.
