Update....I was finally able to locate the sensor (on the side of engine block....drivers side). After a lot of researching, I could only verify the SHO has a single temp sensor...not both a CHT & ECT. Unfortunately, this didn't fix the issue, so I'm wondering if anyone else has had similar issues or has any other ideas.
About a week ago I noticed my temp guage started dancing around while driving, but it was more load based. If I was driving up a hill &/or applying more gas it would increase. As soon as I started coasting it would almost immediately decrease back to normal levels. There was no smell, smoke, rough idle, etc....just the temp gauge.
Day 2 and beyond had been the same except for the temp guage would now max out and the dash would light up with "engine coolant overtemperature." Still 0 other symptoms and no check engine light. As soon as I coast and the temp guage comes down, the message goes away.
No leaking found, coolant levels full, fans coming on, no belt noise, etc which imo rules out all the normal things that would cause it to actually overheat.
Is there possibly another sensor that I'm missing? Or could the male electrical end that plugs into the sensor be the cause? I don't want to keep driving it as is, bc when the guage redlines the computer thinks it's overheating and it goes into a "limp" mode. The moment it comes back down it runs completely fine. Any help is greatly appreciated!
