YES IT CAN SO GET IT FIXED
When service engine light is on on a 2003 Chevy Trailblazer, the problem could be a faulty thermostat, a circuit range performance problem, or any other problem.
The OBD2 code P0128 for a Saturn SC1 indicates a problem with the engine coolant temperature being below the thermostat regulating temperature. This could be caused by a faulty thermostat, low coolant level, or a malfunctioning coolant temperature sensor. It is important to diagnose and address the issue to prevent damage to the engine.
i have the same problem. I took thermostat housing off the block, but cant get out thermostat. Any idea ?
On the 4 cylinder Saturn, follow the top radiator hose back to the engine. Note that there is a housing that is bolted to the engine to which the radiator hose is connected. Remove the radiator hose first, then remove the housing. On the 4 cylinder Saturn's, the thermostat is a part of that housing.
Follow the upper radiator hose from the radiator to the engine and at the engine you will find a housing with the thermostat inside. When replacing it make sure the spring goes toward the engine.
Follow the top radiator hose to the engine, what that mounts to is the thermostat housing, remove this and there is your thermostat. * ** *** **** ***** Actually, on my 1997 SL2, the thermostat is on the bottom radiator hose. I would check the "Saturn Thermostat Pictures" link below, which also has installation and removal instructions.
have vehicle scanned to determine the problem

Thermostat bad or missing or engine not running.
The usual issue with a 2005 Saturn Vue engine light is a problem with the EGR valve. It is best to have a mechanic check out the problem.

Hi, I have that same problem right now, but I took it in for a diagnostic and they told me i needed a new EGR valve, maybe that could be your problem too!
