That "sensor" is a temp actuated switch...the CSI is only active when the starter is engaged. It shuts down as soon as the car is actually started or after a set time has expired. A manual switch will not do you any good.

I suspect your problem lies elsewhere.

your cold start injector could be clogged i replaced mine with a good working one and my car starts first time no problem. Check the CSI time switch and the CSI plug itself. Last check the CSI
