Location of the Coolant Temperature Sensor on a Toyota Tacoma
The coolant temperature sensor on a Toyota Tacoma produced between 1995 and 2005 is located under the hood. To reach the sensor, simply open the hood and look in the rear engine area. The sensor is mounted to the engine block, just above the transmission bellhousing.
For newer models, such as the 2006 Toyota Tacoma 4.0L V6, the exact location of the ECT (Engine Coolant Temperature) sensor may vary. It’s recommended to consult the vehicle’s manual or seek professional assistance for the specific location in these cases.
If you need to replace the coolant temperature sensor, you can find replacement parts at various auto parts stores, with prices starting from as little as $8.79. Additionally, the cost of replacing the engine coolant temperature sensor in a Toyota Tacoma can range between $354 and $432 on average.

Where is the coolant temp sensor on a 3.4 Tacoma?
For the 3.4, Engine Coolant Temp sender (for ECU) is on the front of the lower intake, blue arrow 2 wires. Engine temp sender for the gauge is at the rear, red arrow 1 wire.
Are there 2 coolant temperature sensors?
There are two temperature sensors in some vehicles, one to send information from the engine system to the control unit and another from the control unit to the dashboard. The device follows the principle of dependence of potential difference in temperature.
Where are coolant temp sensors located?
Where is the Coolant Temperature Sensor located? The coolant temperature sensor will be located directly behind the coolant pipe. In most modern cars and vehicles, this is present behind the right cylinder head that is located right underneath the air intake pipe.
Is coolant temperature sensor easy to replace?
Yes, it’s extremely easy but also very dangerous. It is shaped like a big bolt and simply unscrews from the socket. But if this is done when the vehicle is hot it will spray out boiling coolant. So the vehicle must be allowed to sit and cool down with the radiator cap off before changing the sensor.
What happens when coolant temperature sensor goes bad?
Here’s what happens: Faulty readings from the coolant temperature sensor can cause the engine to miscalculate the air-fuel mix in the engine. Any time the air-fuel mix ratio is not in proportion, and if the fuel mixture becomes too rich, the fuel will not be able to burn up inside the combustion chamber.
How do you reset a coolant temperature sensor?
Coolant temperature sensors are resistors and can’t be reset. The engine control unit is the part that actually runs software and just takes information from the sensor. If you think you have a problem with your sensor, test its resistance by attaching it to a multimeter and submerging the sensor in hot water.
Where is the cooler temperature sensor located?
In general, the engine coolant temperature sensor is usually located on the engine block or cylinder head, or on the intake manifold.
How do I know if I need to change my coolant temperature sensor?
To confirm, you could run your vehicle through an emissions test. If everything else is in order, failure in this test should be because of a faulty coolant temperature sensor. Another telltale sign of your coolant temperature sensor not functioning properly is if your engine is overheating frequently.
Is it hard to replace coolant temperature sensor?
Yes, it’s extremely easy but also very dangerous. It is shaped like a big bolt and simply unscrews from the socket. But if this is done when the vehicle is hot it will spray out boiling coolant. So the vehicle must be allowed to sit and cool down with the radiator cap off before changing the sensor.
Can you drive with a bad coolant temperature sensor?
Driving with a bad coolant temperature sensor is not recommended, as it can lead to various problems and potential engine damage. The coolant temperature sensor plays a crucial role in monitoring the temperature of your engine’s coolant and providing this information to the engine control unit (ECU).
