What is the ECT connector?
A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off.
Where are the wires on the ECT sensor?
Advanced auto gave me a two prong plug with a two prong pigtail that has 2 wires. This is what it should when looking up my vehicle for a ect at the store. The one that was on the truck did not look like factory. It was a wire soldered on to the back of the sensor.
Where are the wires on the coolant sensor?
It was a wire soldered on to the back of the sensor.” ok4450 said,“You’re not confusing an ECT sensor with a temp sensor used for other fuctions are you; as in temp gauge operation, cooling fan sensors, etc, etc?” Nevada_545said, “The coolant temp sender for the gauge has one wire, dark green.

What does ECT mean on a code reader?
The engine coolant temperature (ECT) sensor monitors the fluctuations in the temperature of the engine coolant. This data is sent to the ECM, which uses this data to regulate the air to fuel ratio, cooling fans, and ignition spark timing needed by the engine.
Is there a fuse for the ECT sensor?
There isn’t one per se. There will be a fused wire with voltage to the instrument cluster (your owners manual should indicate which fuse), but the temperature sensor is providing a variable “resistance to ground,” which the temperature gauge in the dash is reflecting.
Where is the ECT PWR button on the Toyota Tacoma?
ECT PWR Button. If you look at the dash of your 3rd Generation Toyota Tacoma, you’ll see an ECT PWR button right under the navigation system and between the Blind Spot Monitor (BSM button) and the Parking Assist Sensors (P button).
What should the voltage be on the ECT sensor?
The normal value of the ECT sensor voltage is 2V at cold engine and 0.5V at warm engine. A defect sensor can indicate a voltage of 1.5V at cold engine and 1.25V at warm engine, thus causing difficulties of starting a cold engine and a presence of rich fuel mixture when the engine is warm.
When do you use the ECT PWR button?
The customer service person at Toyota did say that some people use the ECT PWR button when they need to accelerate quickly, such as when entering the highway from the frontage road ramps, or when legally racing the vehicle.
What does the coolant temperature sensor ( ECT ) do?
The engine coolant temperature sensor is temperature-variable resistor, which usually has a negative temperature coefficient. It is a two-wire thermistor immersed in coolant and measures its temperature. The onboard computer uses the signal of ECT as the main correction factor when calculating the ignition advance and the injection duration.
