Here is the location of the engine temperature sensor and all the other sensors with a guide to help see whats going on if the sensor does not fix it.Ĭheck out the diagrams (Below). There is a chemical test to check for this. A leaking head gasket is usually accompanied by the loss of coolant from the reservoir. Thermostats have to be hit with hot liquid. The gases that get into the cooling system can pool under the thermostat and cause it to not open. A large butterfly collection in the radiator will do that too.Īnother real good suspect is a leaking cylinder head gasket. Your car is too new for this, but if running the heater on "hot" and the fan on a higher speed brings the engine temperature down, corroded cooling fins on the radiator are a good suspect. That is not needed at higher speeds where natural air flow is sufficient. start the engine up it runs for a little while at an idle then Engine Coolant over Temp comes on. If speed is a contributing factor, and the overheating only occurs at low speeds, suspect the radiator fan is not turning on. First you have to determine what affects the overheating. The more the input readings, the better the output decisions are.The sensor is telling you the engine temperature is too high. One ECT sensor might not be as much reliable to operate the fan efficiently. This secondary ECT Sensor works together with the primary ECT Sensor to optimize the working of the car and give an accurate reading of the coolant to the car ECU before it is heated up, saving it from potential overheating problems.Īdding an ECT sensor is another way to get a more accurate reading. To keep the radiator of the engine working properly and to regulate the temperature of the engine constantly, locating these leakages is also very important. However, the one location where the secondary ECT Sensor is seldom placed in the radiator is the outlet of the radiator tank or pipe as it is the most common place for leakage of the engine coolant fluid. The location of this sensor is not very common and is found in different locations in different cars. The other Engine Coolant Temperature Sensor is known as the secondary ECT sensor or the ECT sensor 2. The sensor cancause a check engine light as well as overheating. View with cosmetic engine cover installed. The sensor is connected to the air intake temp sensor and will be mounted on the right valve cover. Ford 1.5L I4 Ecoboost Engine Sensor Locations. This cylinder head closes the top opening of the cylinders and packs it into a casing forming a combustion chamber for the fuel and air to mix and react. The 2014 Ford Escape 1.6 cylinder head temperature sensor can be found on the back of the engine on the passenger side of the engine bay. In an internal combustion car’s engine, the cylinder head is placed on the top of the car’s cylinders above the cylinder block. This sensor is located on the coolant passage next to or in the thermostat housing of the cylinder block or cylinder head. The main Engine Coolant Temperature Sensor is known as the primary ECT sensor or ECT sensor 1. One sensor is located near the thermostat valve housing, and the second one is located in the radiator outlet tank or pipe. The pair sensors can be installed in different places, depending on the make, model, and year. Most of the cars that are being used nowadays contain pairs of Engine Coolant Temperature (ECT) Sensors for the purpose of sending accurate and precise information to the car ECU. These sensors are directly connected to the car ECU for measuring the temperature of the engine coolant. This sensor consists of wires ranging from 1 to 4.

When the temperature exceeds a certain threshold, the temperature sensor was used to make the connection of the earth to the radiator fan’s relay, and the radiator fan had to turn ON. In the old model cars, there was an engine coolant temperature sensor (thermal switch), mounted on the radiator outlet tank or pipe, which was used to turn on the radiator fan. Where Is The Engine Coolant Temperature (ECT) Sensor Located Single Wire Coolant Temperature Sensor
