Looked over all wires and no breaks or worn through wires. Sensors tested fine as well.Two things I would do. I would test the sensor to see if it is good, there are a lot of junk parts out there(check the old one too). If the part is good I would start tracing the wires back to MPEM and look for damage, it may be grounded.
From what i remember from my 98 GTX ltd, the water temp sensor doesn't have a warning buzzard, only the engine temp sensor.you said you changed the temp sensors? which ones, the one in the head and the one in the muffler?
you checked the harness? did you measure them with an ohm meter?
at start up on the water your sensor is saying 30 degrees? on your gauge? if my memory is right your gauge displays water temp of the lake your in not what the engine temp is
i guess what I am trying to find out is what water temp sensor are we talking about.From what i remember from my 98 GTX ltd, the water temp sensor doesn't have a warning buzzard, only the engine temp sensor.
My 98 doesn't have that exhaust sensor, but you bring up a good point, check your 02 setup and look at that too . Do you know if it has a way to differentiate between the two high temps errors?i guess what I am trying to find out is what water temp sensor are we talking about.
when the gauge displays temp on the gauge that’s the lake temp read by the speed sensor or air temp read by the sensor in the hood, when there is a warning buzzer with a overheating message that is either the head temp or the exhaust temp warning, but are different sensors than what is displayed as temp on the gauge.
Both the head temp and exhaust temp sensors should test out at 2280-2740 ohms
Couldn't you disconnect the exhaust sensor and head sensor then hook one at a time to isolate the faulty wires/sensor?The 950 carbs don’t have an exhaust temp sensor.
The only way to know which one is causing the fault is to hook it up to a computer or test the sensor and circuit and see which one is out of range.
