Hi,
I'm assuming you mean the coolant temperature sensor - the one that drives the temperature indicator gauge in the dash.
If that is the case, the temperature sensor is located right next to the thermostat housing. This is located on the left side of the engine (driver side), just below the throttle body.
I have included a link that shows where the thermostat housing is located, and if you look closely, you will see the wires and connector that go to the sensor.
Good Luck, Greg
where is the coolant temp sensor on a 2004 1.5 almera
THE temp sending unit 4 the inside gauge usally has 1 wire & the sending unit 4 the Computer has 2 wires.
The air temperature sensor in built into the Mass Air Flow sensor.
There is possibly a light sensor if it has auto headlamps. or a temp sensor for climate control
It is on the drivers side of the block.
Temp sending unit for ecm. most likely sensor is bad computer cant read engine temp, fast idle do to cold reading
it should be on the inlet manifold there will be a wire that slides over the sensor
In the glove box.
The coolant temp sensor is the two wire sensor located near to where the upper radiator hose hooks to the engine.
The ambient air temp sensor on a 2004 Dodge Neon is located at the front of the car, year the headlights. It receives fresh air rather than heated air from the engine for the most accurate readings.
It is in the engine cover, which also contains the air filter.
Usually ambient sensors are located in front of the radiator.
