Where is the heat sensor located


Hi , your engine has two sensors relating to coolant temprature , one is the ECT located just under the coil pack and it sends your temp signal to the ECU , the other is the sensor that sends the temp reading to the dash , and it is located just above the alternator on the intake manifold . hope this helps a bit.
Kind regards; Higgins

The ECT sensor is bad in m 1990 toyota 4runner and is bigger than the x40, i need the bigger one and am having trouble finding it.


I am not sure you are very clear here. ECT's (engine coolant temperature sensor) have a part number for each engine model and year.

How do you fix a code#P0125 on a 1998 toyota 4 runner?insufficient coolent temp. for closed loop control?


first check radiator level if it is full and the heater is working good make sure temp gauge is functioning c orrectly it is most likely the coolant temp sensor but if this is a high milage vehicle and you have owned long time and never changed i would also replace thermostat and check plug to temp sensor forr good conections and good wires

Where is the temp gage sensor location 2001 merk cougar


Hi there,

The temperature gauge relies on readings from the Engine Coolant Temp (ECT) Sensor.

The ECT sensor is usually located on (or near) the thermostat/coolant housing.

Refer to component No. 8 (2.0L Engine):

Refer to component No. 9 (2.5L Engine) locate under bypass tube:

Hope this helps.

Where is the coolant temperature sensor on a 1999 honda crv?


Good Day
the ECT sensor is located on the cyl head near the coolant outlet, so if you are looking at the eng from the front of the car stand in the middle you will see the rad put your left hand on the rad then with your hand on the rad(left side) move your hand towards the back of the eng approx 6" the ECT will be around that area:
if you are replacing the ECT after putting the new ECT in warm the eng until the coolant fan turns on and off twice.
I hope this helps

Cheers

P0446 Evaporative Emission Control System Vent Control Circuit


ECT stands for engine coolant temperature. So I would start by making sure that your engine coolant system is not leaking and is full of coolant.If you want to tackle the job yourself you could purchase Haynes techbook # 10206 OBD -2 and electronic engine management systems or check your local library they may have a copy and they have troubleshooting steps you can do with a scan tool or multimeter. Good luck and hopefully this helps you a little.

ECT - Engine Coolant Temperature Sensor

The engine coolant temperature (ECT) sensor (Figure 27) is a thermistor device in which resistance changes with temperature. The electrical resistance of a thermistor decreases as the temperature increases, and increases as the temperature decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to temperature.
Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow.
Voltage that is dropped across a fixed resistor in a series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The ECT measures the temperature of the engine coolant. The sensor is threaded into an engine coolant passage. The ECT sensor is similar in construction to the IAT sensor.
