If unplugging the coolant sensor unit will allow full power?

Customer Question

If unplugging the coolant sensor unit will allow full power? Our 6.0 gauge is saying engine is overheating but it is cool. It will say it is hot upon startup. I am unable to get a replacement sensor right now as traveling and hauling livestock. Temperature in teens and I need to get on home. No power when the gauge pegs red
JA: Is the power loss consistent, or does it fluctuate?
Customer: Consistent
JA: What is the model/year of your Ford?
Customer: 2004 F350 SD
JA: Are you fixing your F350 yourself? What have you tried so far?
Customer: Needing a quick fix to get home to then get it properly fixed
JA: Anything else you want the mechanic to know before I connect you?
Customer: No

Unplugging it will make it worse. It will limp mode the engine to idle only if you had the 2011 update done on the PCM. Otherwise it just does a 15% cut in power. It all depends on the updates you had on the PCM and that is unknown until you plug the truck into the Ford IDS scanner and check it.
