If the car is running well at idle, but the temperature gauge fails to reflect engines' temperature, here are few possible problems that may cause that:
Please make sure that your coolant system is bled properly (per Nissan factory procedure) and has no air bubbles before replacing sensors!
- Most of the time the factory SR20DET engine temperature sensor fails between the time the engine ran in Japan till it is started here on our shores.Replace the one-wire temperature sensor on the engine block, underneath the intake manifold runners.
