Hello everyone
My wife's Trax had some issues and we narrowed it down to a faulty radiator coolant temperature sensor. Apparently there's an engine coolant temperature sensor also and if they differ too much the ECM goes into "protect mode".
We have a new RCT sensor ordered and just waiting on shipping.

My question is can we unplug the RCT sensor until we get the new one put in?

I know if the ECT sensor is unplugged the fuel to air mix will be set to the current ambient temperature. Once the engine heats up the mix would be too rich. Our ECT sensor is working fine. It's the RCT sensor that's faulty. That's why I think it would be ok but, I'm no mechanic. So I would very much appreciate your help with this.
