The thermostat may fail to close completely, causing the Check Engine Light to illuminate. This problem will prevent the engine from reaching normal operating temperature; a new thermostat should be installed.

Engine light comes on. Mechanic states it's the thermostat and needs to be replaced.
Check engine light on and remote start doesn't work. Was told I need to replace the thermostat.
