Coolant temperature sensor

Recommended Posts

Can a defective coolant temperature sensor in a Nissan FB14 Sunny with a GA15DE engine cause the vehicle to hard start when the engine is cold?

Yes. Among many other possible causes. One of the inputs to the ECU to determine the proper air to fuel mixture is the ECT (Engine Coolant Temperature) sensor reading. Bad sensor means inaccurate values. This means the proper air to fuel mixture doesn't reach the cylinders. The car might not start due to this. 

Get the ECT sensor tested.

Will this affect the starting/cranking?

The starter motor is not affected, so it will crank the engine as normal.
