This 2 wire sensor (Figures 1 and 2) is checking metal temperature and is do not use an engine coolant temperature (ECT) sensor, the CHT sensor is The wiring diagram provided in Figure 5 shows that the ground side of.
My F 4×4 just started having this same problem. Strange thing @ jdarnold remove the sensor wire and ground it, the temp gauge should move to HOT.
That would If temperature gauge indicates hot, replace coolant temperature sensor. Disconnect instrument cluster harness connector C As soon as I slowed down the temp gauge went back down to normal.
Check the wiring as well it could be loose on the sending unit. engine coolant temp sensor (see the diagram above kindly provided by @knfenimore.
Engine Coolant Temperature (ECT) Sensor Circuit Low Input Short to ground on ECT signal circuit; Faulty or damaged connectors; Wiring harness damaged. Hello, I have a Explorer.
The temperature gauge recently stopped working all together and the “check gauge” light remains lit at all times.mercury mountaineer with liter engine – wife was making*****to work – tempature gauge warning came on- temp gauge went all the way to hot – turned around and drove home – car began steaming as she pulled into driveway. mercury mountaineer v8 exact location coolant temperature sensor – Answered by a verified Mercury Mechanic My Mercury Mountaineer 4×4 with the liter v8 will occasionally show as overheating with the temp gauge maxed, the coolant symbol showing on the info display and will go .

Mercury Mountaineer Owner’s Manual pages. Engine coolant temperature gauge: Indicates engine coolant temperature.
At normal operating temperature, the needle will be in the normal range (between “H” and “C”). If it enters the red section, the engine is overheating.
The coolant temperature switch, also called the coolant temperature sensor, is a switch that reads the engine coolant temperature and sends a signal to the engine control module, or ECM, to control other functions of engine operation such as the air-fuel ratio.

Checked antifreeze, replaced thermostat, flushed system. Now temp gauge is fluctuating between cold – normal.Diagnosing Ford’s Cylinder Head Temperature (CHT) Sensor | Search AutopartsMercury Mountaineer Coolant Temperature Switch (Sensor) Replacement Costs | YourMechanic Estimates
