Yes. The ECTS is the coolant temp sensor. And they can impact the air/fuel ratio that the computer determines for optimal running conditions. They will also be the guide the computer uses to regulate the cooling fan.
The Old style ECTS that was prone to failure was updated in 2000. I have not heard of any problems with them since then, although anything is possible. I would check the connection and the wiring for sure.
You need to retrieve the codes and let us know specificaly what they are to narrow down the possibilities.
