The 2003 Toyota Camry coolant temperature sensor can be found on top of the engine. The coolant temperature sensor will be near the center of the exhaust manifold.

The ECT or the Engine Coolant Temperature Sensor is a switch. This switch is located on the bottom of the radiator in the 1996 Camry.
Your temperature gauge does not work, and the engine might run rough.
The coolant temp sensor for a 1977 Camry is important to the engine running properly. The sensor sends a signal to the computer to keep the air/ fuel mix correct.
You need to check coolant temperature sensor and the water pump.
The intake air temperature sensor is located on top of the intake. In a 1990 Toyota Camry the air temp sensor assures the ECU the engine is running at optimal temperature.
It depends on which of them. The one for coolant is located in the water inlet. Ambient temperature sensor is located in the filter box.
If it's cold outside, it's because ECU use ambient temperature sensor and coolant sensor to manage RPMs. After you start the car the coolant temperature is low and ECU sets RPMs very high, when it gets warm RPMs drop down until engine reaches operating temperature.

If the coolant level is correct there are at least two reasons. First one is the thermostat and second one is the temperature sensor. You have to check basically the coolant level, the thermostat and the temperature sensor.
The Engine Coolant Temperature in the Engine is higher than it should be. Check your radiator coolant level - also your radiator may be clogged or thermostat may be stuck.
