hopefully easy question. still fighting the over heating issue, but I have the stuff for the head gasket replacement I am doing after vacation.
Can a sensor fail and give the wrong signal? let me explain. from what I can see on the all knowing google world, when a temperature sensor fails, it drops to -0 ohms. I am not seeing much that shows that when it fails it shows that it sends a signal that the real temp is hotter than what it really is. Everything I can find (so far) says the sensor either works, or it sends 0 ohms all the time.
Because my temp (form the ECU, not the gauge) shows the temperature climbing, not spiking at extreme hot, I would say my sender is fine. My laser reader puked so I cant verify the head temp vs what the ECU is reading.
Would it be worth changing out the sensor? or is this just wishful thinking that I wont have to do the head gasket.
I really have no other symptoms of a head gasket failure, no smoke, no oil in the coolant, no coolant in the oil, no erratic idle or running. Just the less than 5 minutes to 200+ degrees even at idle.
