So I've just had a fault diagnosis check at Nissan.
I've been told that it's the mass airflow sensor and the engine coolant temperature sensor. (By the way, the self diagnosis check did not show up a mass airflow fault)
I have just replaced the engine coolant temperature sensor for a brand new one! So don't know why this is faulty, unless the ECU is not being reset properly.
They said that you sometimes can't completely remove the memory in the ECU and I will have to pay them again to reset the ECU!
QUESTIONS:
Is the mass airflow sensor fixable using the re-soldering fix or will I need a new throttle body?
Do I really need to go back to Nissan to reset the ECU?
He said something about the engine coolant temperature sensor was on the exhaust. I didn't know there was one on the exhaust, is there?
