Modern vehicles are equipped with multiple temperature sensors. They are used to advise the engine computer and driver on the condition of the vehicle systems. Common automotive temperature sensors include coolant, transmission, ambient air temperature and engine oil.
An oil temperature sensor monitors the oil in a vehicle to ensure that it remains at the right temperature. It is important that the oil is not allowed to get too hot.

To monitor the coolant temperature and send that info to the vehicle's computer and or temp gauge.
The temperature sensor on a Ford Focus is located on top of the engine, near the upper radiator hose. It sends a constant signal to the vehicle's computer about its temperature.
The coolant temperature sensor of a 1998 Nissan Altima is located beside the upper radiator hose. It constantly updates the vehicle's computer about the engine's temperature.
It is important to know the location of all the parts in a car. The inlet air temperature sensor on this vehicle is in the intake manifold.Ê
There are several temperature sensors on a 2001 Chevy Monte Carlo. A temperature sensor for outside temperature is located near the passenger side wheel underneath the vehicle. A manifold temperature sensor is located in the manifold. There is also an air temperature sensor in the hose that leads from the air filter to the motor. Still another temperature sensor is the thermostat in the upper radiator hose near the water pump.
coolant temperature sensor are located where the coolant runs in the block near the thermostat housing normally the connector are on top of the sensor and the sensor itself screws in with a deep socket. The temperature sensor is usaully located where the coolant runs OUT of the engine close to thermostat housing.
Vehicle make, model & engine size needed first.
The outside temperature sensor on a 2003 Altima is located just behind the front bumper. it is on the passenger side of the vehicle in the undercarriage.
The coolant temperature sensor on a 1999 Mondeo is located on top of the engine, in the intake manifold. It constantly updates the vehicle's computer and controls the cooling fan.
Outside temperature sensor either unplugged or broken. Do an internet search for the sensor using the specifics of your vehicle (ie 2003 BMW 330i outside temperature sensor). You will find replacement parts and diagrams of how to fix this yourself.
