If you unplug the coolant temperature sensor the PCM will see the lack of signal as a extremely low coolant temp. The PCM will set an injection rate that will be excessively rich. The coolant temperature sensor acts as a choke on an engine and adjusts fuel injection rate from rich when the engine is cold to lean for a warm engine.

The ECT (Engine coolant temperature) sensor is basically a thermistor that changes resistance with temperature. Usually a two wire sensor, a 5Volt reference from PCM (Powertrain Control Module) and ground signal to PCM. This is different from a temperature SENDER (which usually operates the dash temperature gauge and operates in a similar way as the SENSOR, only it's a different circuit than ...

Unplugging the engine coolant temperature sensor before starting the engine may result in a no start, especially likely on a cold morning. Although the PCM will see the sensor is unplugged and has a default fueling strategy for such an event. It is more of a one size fits all approach and so a cold start in colder temperatures may prevent the engine from starting.
