2001 Saturn L100 Problems

A/C off for Engine Protection and Engine Reads Cold

The Saturn L100 may display the warning message "A/C off for Engine Protection" on the instrument panel. This may be accompanied by illumination of the check engine light and the temperature gauge reading cold at all times. This is a feature of the engine that is activated by the power control module when it detects the engine warming up too slowly. The OBD trouble code P0128 may also be stored. 

The cause is simply a worn out thermostat that stays open at all times, preventing the engine from reaching the proper operating temperature. 

Replacement of the thermostat will correct the issue. 

Check Engine Light Due to Gas Cap Issue

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

Check Engine Light Due to Engine Misfire

The ignition module or an ignition coil may fail causing an engine misfire, the Check Engine Light may or may not illuminate. Diagnoses will be required to determine the cause and needed repair.

I have owned this car for 10 years, having bought it in 2003 with 18,000 miles on it. It now has 134,00 miles and is still running great. It is reliable and still looks like a much newer car.
