By purchasing a service manual, you can determine where the sensor is located and … Temp Evap Sensor is $37 on autohausaz.com, not $100 as pdf says. Designed specifically for your vehicle, Motorcraft products meet stringent Ford Motor Company standards and feature OEM quality without the OEM price. Pour warm water on the sensor, and check for a change in the resistance. But I want to test it to verify. How to Test a Thermistor. Allow the sensor to cool before further testing. It is a part of the vehicle’s AC system, and as its name implies, detects and monitors the temperature of the AC system’s evaporator. I looked where some videos showed you but is it in a different spot for a 2015 ford escape. The evaporator contains the Beacon II Controller, electric expansion valve, pressure transducer, distributor, orifice, transformer and three sensors. The evaporator temperature sensor or switch is a component commonly found on many road going vehicles. Remove the evaporator temperature sensor (see page 21-67). Then pour warm water on the sensor, and check for a change in resistance. • Room sensors may be left connected on ALL evaporators. 1. please I need help 2015 Ford Escape SE (HELP) The coolant sensor for fan rely control is locate on the head side of the thermostat where it can monitor the temperature when the thermostat is closed. It's a simple on off switch set at ~40ºF, with ~ 4ºF range between on/off set point. The engine coolant temperature (ECT) sensor test is simple and can help you fix your car faster. He told me it would require taking apart the dash to access it, … The Symptoms Very similar to having low AC gas. The air-conditioning unit would then continue to cool the air despite the fact that the evaporator was already iced up. The positions of all temperature and pressure sensors are also indicated. Step 2: Start the vehicle. The design of the hvac plenum ducts is another factor that we need to take into account while running an efficiency performance test. Guessing, matching the OEM specs can bring risk. An evaporator cools the refrigerant in the HVAC system.

The A/C evaporator works in the opposite sense as the condenser. 5. evaporator temperature sensor diagnose - Read online for free. It blinks between the test number and the test result, ie test 5 is evap temperature sensor reading in F so if it says 155 like mine did when it went bad it means the car is thinking it's 155* F at the evap core, which is out of bounds, which means your compressor will NOT engage. Thermometrics Evaporator Core Temperature Sensor measures evaporator core temperature in a vehicle's HVAC system so that it doesn’t freeze over, preventing a costly repair. It would freeze at temperatures around 0 °C and thus obstruct the air stream. Since the evaporator core operates at temperatures very close to 0°C, it is important to have an accurate and robust thermistor to measure its temperature to prevent the core from freezing. 2. 3. This includes but not limited to Chevrolet, Dodge, Ford, Ram, etc. It is a part of the vehicle’s AC system, and … These components are all factory mounted and wired. Let the engine cool before doing this, as you can be severely burned. Resistance, B-value by user determine. Step 2. R-134a refrigerant. As the air passes the sensor, it reads the temperature and compares that reading to the setting on your thermostat.

As before, connect the red probe to the + wire going to the sensor, and connect the black probe to the ground wire going to the sensor. Connect a 5 amp fused jumper wire between the following: Check for self-test DTCs. Reconnect the sensor’s power source. Allow the sensor to cool before further testing. The powertrain control module (PCM) uses three simple but robust components to purge gas vapors and test the gas vapor system for leak integrity. Maintain the same probe – multimeter connections. The evaporator sensor would then measure a higher temperature than the real temperature of the air coming from the evaporator. I think my problem might be a similar unit. if the hvac control module sees the temp going too low, it will send a communication message to the pcm to turn off the a/c compressor until the evap temp returns to an acceptable range. 4.
