· This is the first video in a series I am developing on how to test various types of sensors. This video covers a few of the test methods used to diagnose tem...
NOTE: Before testing the sensor, check for HVAC DTCs (see page 2 1 - 9). 1. Remove the evaporator temperature sensor (see page 21-67). 2. Dip the sensor in ice water, and measure the resistance between its terminals. EVAPORATOR TEMPERATURE SENSOR. Terminal side of male terminals. 3. Pour warm water on the sensor, and check for a change in the resistance. 4. Compare the resistance …
· The evaporator sensor will either be mounted to the evaporator or the evaporator case. The exact location of the evaporator varies from vehicle to vehicle, but it is generally located inside or underneath the dash. Consult the repair guide for your vehicle to determine the exact location. Part 2 of 3: Remove the evaporator sensor. Step 1: Disconnect the negative battery cable. Disconnect the ...
· In this video we explore how to test and replace the EVAP pressure sensor P0450. Trouble code p0450 deals with an improper voltage signal from the EVAP press...
· How do you test an evaporator temperature sensor? Find the A/C evaporator temperature sensor and inspect it thoroughly. Generally, this is located inside the HVAC air box. The sensor is mounted to the evaporator itself, if not very near it. Usually, you can get access to it by simply looking under the dash. READ: How much oil does a 2001 Dodge Cummins take? How do I know if my car evaporator ...
A/C Evaporator Temperature Sensor Test. 1. Remove the evaporator core and the evaporator temperature sensor. 2. Dip the sensor in ice water, and measure the resistance between its terminals. 3. Then pour warm water on the sensor, and check for a change in resistance. 4. Compare the resistance readings with the specifications shown in the graph; the resistance should be within the ...

· Im replacing my evaporator and figuring I should test the temp sensor (the piece next to the expansion valve that dips a metal piece into the evaporator fins). Now seems like an good time to replace a faulty one :-)
· The evaporator temperature sensor or switch is a component commonly found on many road going vehicles. 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. The switch is usually installed directly on the AC evaporator or in close proximity, and monitors the temperature of the evaporator so that it can be ...
EVAPORATOR TEMPERATURE SENSOR. The EC light was on because of the evap sensor----wrong--the EC light was on because of 1241 low refrigerant level and the low refrigerant level produced a high evaporator temp which you thought was a bad sensor so you went out and wasted your money on a new sensor-----now you haven't solved the problem--- you have a leak--go to an AC shop have them …

Evaporation. Evaporation is the process in which a liquid changes to the gaseous state as the free surface, below its boiling point, through the transfer of energy. Evaporation is a cooling process- the latent heat of vapourisation (~585 cal/g of evaporated water) must be provided by the water body.
Locate the evaporator, which is a block or grille-type component connected via hoses and tubes from the compressor, which has a belt and pulley system. Feel the two tubes leading from the evaporator to the firewall. If the tubes are not cold to the touch, then there is no refrigerant traveling through them, meaning that your refrigerant is either too low or the pressure sensor is not working ...
· The evaporator temperature sensor or switch is a component commonly found on many road going vehicles. 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. The switch is usually installed directly on the AC evaporator or in close proximity, and monitors the temperature of the evaporator so that it can be properly regulated to stay within reasonable operating temperatures. When the sensor …

Remove the air intake temperature sensor after first removing the air intake housing. … Remove the evaporator temperature sensor. The A/G evaporator temperature sensor performs an important role in the proper procedure of the HVAC (Heating Air flow and Air Fitness) system. Generally speaking the evaporator core is located inside the HVAC (heating ventilation and air conditioning) air box ...
· However, you should test your sensor first to make sure that’s where the problem lies, and you don’t have a deeper issue that needs to be repaired. With your handy multimeter, you can easily take a few readings that will tell you if your sensor is functioning properly. Steps . Part 1 of 2: Connecting to the Temperature Sensor Download Article 1. Place your vehicle in park, turn off the ...
