Where is the engine coolant temperature sensor low input located on a kia 2007 spectra


Not low input sensor...P0117 KIA - Engine Coolant Temperature Sensor 1 Circuit Low Input

Possible causes
Low engine coolant level
Faulty Engine Coolant Temperature (ECT) sensor
Faulty engine coolant thermostat
Engine Coolant Temperature (ECT) sensor harness is open or shorted
Engine Coolant Temperature (ECT) sensor circuit poor electrical connection

Just replace coolant temperature sending unit....

Location air temp sensor


Location of Intake Air Temperature Sensor:
The intake air temperature sensor, which is mounted on the mass air flow meter, monitors the intake air temperature. The intake air temperature sensor has a built-in thermistor with a resistance that varies according to the temperature of the intake air. When the intake air temperature becomes low, the resistance of the thermistor increases When the temperature becomes high, the resistance drops .

Where is the tempurture cooling sensor located on a 1994 buick regal


The coolant temperature sensor is a thermistor mounted in the engine coolant stream. A thermistor is an electrical device that varies its resistance in relation to changes in temperature.

For 2.5L engines, the coolant temperature sensor is located on the left side of the cylinder head.

For MFI engines, the coolant temperature sensor is located on the intake manifold water jacket or near (or on) the thermostat housing.

Locationing temp sensor on 95 rodeo 3.2


There are SEVERAL temperature sensors on your vehicle (battery temperature sensor, intake air temperature sensor, evaporator temperature sensor, etc....you really should specify.

I will assume you mean the Engine Coolant Temperature (ECT) sensor.
If this is the one you are looking for, it is located at the rear of the intake manifold on the left side.

Where is the iat sensor located on a 1999 chevy cavalier 4cyl


The Intake Air Temperature (IAT) sensor determines the air temperature inside the intake manifold. Resistance changes in response to the ambient air temperature. The sensor has a negative temperature coefficient. As the temperature of the sensor rises the resistance across the sensor decreases. This provides a signal to the PCM indicating the temperature of the incoming air charge. This sensor helps the PCM to determine spark timing and air/fuel ratio. Information from this sensor is added to the pressure sensor information to calculate the air mass being sent to the cylinders. The IAT is a two wire sensor, a 5-volt reference signal is sent to the sensor and the signal return is based upon the change in the measured resistance due to temperature.
