Where can I find an evaporator temperature sensor?
The evaporator temperature sensor is one of the control devices found in automotive air conditioning systems. It’s a negative temperature coefficient thermistor.
How to replace an EVAP temperature sensor ( switch )?
Step 1: Determine the location of the sensor. Each vehicle that utilizes an EVAP temperature sensor has a unique location and process for replacing this component. By purchasing a service manual, you can determine where the sensor is located and the precise steps needed to replace this component. Step 2: Disconnect the vehicle’s battery.
What does the temperature sensor on an air conditioner do?
Car AC Maintenance. European Auto A/C Repair near me. The evaporator temperature sensor is one of the control devices found in automotive air conditioning systems. It’s a negative temperature coefficient thermistor. It changes resistance according to temperature changes in the evaporator core.
What should the temperature of an evaporator be?
The evaporator temperature sensor acts as a protection device maintaining the evaporator temperature between 34º F and 37º F. These limits could vary depending on the ambient temperature in Automatic temperature control systems.
Is there a problem with the EVAP temperature sensor?
Noted below are a few of the common warning signs that a problem with the EVAP temperature sensor exists. No cold air from the AC system: Usually when a vehicle has a coolant leak on a closed loop system or is running low on refrigerant, the air conditioning system slowly stops blowing cold air into the vehicle.
How to remove an evaporator temperature sensor ( switch )?
Most sensors are screwed into the AC condenser and held onto the sensor by a secondary clip. To remove the sensor, you’ll need to remove the support clip first. After the clip has been removed, you can unscrew the sensor by pressing down and turning the switch to the left. Step 7: Remove electrical harness from the old EVAP temperature sensor.
Where is the temperature sensor on an evaporator compressor?
In this case, the compressor itself is fine, but the usual suspect is the evaporator temperature sensor located under the dashboard. Tip: Most service manuals indicate that this job takes between 5 to 7 hours to complete. The majority of this time is spent removing dashboard and interior components and reinstalling them.
How is the temperature of an evaporator controlled?
The operation of this luxury feature is controlled by a very small sensor called the evaporator temperature sensor or EVAP temperature switch.
