MAP THERMOSTAT

MAP thermostat stands for "Map-Controlled Thermostat." It is a type of thermostat that is controlled by the vehicle's engine control module (ECM), also known as the engine control unit (ECU).

Unlike traditional thermostats, which rely solely on the temperature of the engine coolant to control the flow of coolant, a MAP thermostat takes into account other factors such as engine load and ambient temperature.

The MAP thermostat works by using a heating actuator that opens and closes to regulate the flow of coolant between the engine and the radiator. The opening and closing of the actuator are controlled by the ECM, which uses data from various sensors to determine the optimal operating temperature for the engine.

A faulty map thermostat can cause a variety of issues, including poor engine performance, increased fuel consumption, and overheating.

the MAP thermostat is a more advanced and precise type of thermostat that allows for better control of the engine's temperature, resulting in improved performance and efficiency.
