[@MikkoRantalainen]

If you just want to bypass the evaporator temperature sensor, you can just stick an adjustable resistor instead of getting a new temp sensor. Potentiometer set between 100 ohms and 100k ohms should be okay to replace any 2 wire sensor if system is happy with static sensor value. However, that should be considered a workaround, not a fix for A/C problems: this sensor is supposed to monitor the evaporator and avoid getting it frozen. Modern cars have adjustable A/C compressor and the system tries to run the evaporator around 4 °C (40 °F) when A/C is enabled. If the sensor sees higher temperature, the A/C compressor is pushed harder to bring down the temperature. If the sensor sees lower temperature, A/C compressor is adjusted to produce less cold. If you put a sensor outside the evaporator housing the system will be running the A/C compressor at full blast at all times and your evaporator ends up freezing the water extracted from the incoming air. If you run short enough drives or toggle the A/C off manually every now and then, this workaround might be okay. However, if you go for a long drive with a setup such as this, your evaporator could freeze as a solid block of ice and the freezing ice might end up breaking the evaporator which is even harder to replace than the workshop way of replacing this sensor. Either way, if your sensor bypass tells the system that the evaporator temperature is more than ~ 4 °C the system will basically maximize your fuel usage and compressor wear.

So, Shop only charge for $80 me to find out what the problem was. I started to look in you tube and i found your video I did same thing you did I have the the Lincoln zephyr 06 and coulnt find the sensor so did just like you i order one from Ford fusion. And it worked!!. You a life saver sir! 👍 You save me hundreds of dollars!! Thanks!.

Worked for me. Thanks for the video. Mine was 2 and 4. Nothing was in the third slot.

[@metalhalide4043]

I read that thermistor resistance can increase over time (Thermometric Drift), they are NTC (Negative Temperature Coefficient) as temperature goes down resistance goes up and vice versa, so it will turn off the compressor at a higher temperature over time as resistance increases, these are used now in place of the low side pressure sensor.

[@geldonmana3257]

Thank you for this video man, this helped alot

[@hmongwild]

I was just thinking the same. My gx 470 i notice when i have my fan on low. My compressor kick off and on every 5 seconds. Then when i have it high more air come through and it takes longer for the evap to cool so my compressor stay on longer. So im going to buy a new sensor and stick the probe inside the foot hose that way it gets some sort of reading instead of ac full blast and freeze my evap. I will try both. You the man.

[@vlahomozara1233]

Nissan Xtrail X-trail Rogue T32 2015. Aircondition started to work erraticaly. Then, I would work for first 10 seconds and switch off the compressor. The issue was this very same sensor, except it is easier to take out than from this car. I didn't have new sensor at hand, so I used 2K resistor instead of sensor. Now works beautifully!! Thanks

What type and size of connectors did you use to connect the wires to the temperature sensor pins? I'm guessing you used 18 gauge wire.

[@boydnewlin4020]

Your AC is cycling because you replaced the evaporative temp sensor but rather than replacing the original, you put a new one which is now located under the glove box? The other bypass method is using a thermsistor but that could have your compressor freeze under certain conditions right? I am curious if you have the evaporative temp sensor under the glove box, will it work the same way as if you replaced the original in the original place?

[@halo9lady]

Awesome!

47K ohm resistor between 13 and 15 works great.

[@carsrcool7149]

Goid vid !

[@cmcken1]

From an engineering standpoint, this will cause an issue in some vehicles. This type of bypass should be approached with knowing that on certain models, the computer will have no way of reading the temperature of the A/C evaporator is inside the HVAC HAA / HAD / Airbox thus, if it is icing up, the controller will keep the compressor energized thus inducing expensive damage to the evaporator core. When that occurs, you'll lose the oil in the system and the compressor will get red hot and seize up - often igniting something under the hood thus resulting in a CAR-B-Q event on the side of the freeway. Consumers need to be aware of that and how A/C failsafe systems function by design. Now, if one were doing this with just the internal cabin thermistor - this isn't a problem and is doable / safe. But, if one is jumping the evap core - you've just removed the failsafe mechanism to cut power to the compressor and can lead to catastrophic failure which will be quite costly. When the AC Core blows-up, contamination enters the HVAC system thus leading to every component having to be replaced. Approach with caution on this mod. IN a temporary - band-aid, it may be worth a risk but, even at that, there may be a reason why the OEM sensor went out in the first place.

[@efrensaclolo7021]

[@beng6744]

Thanks for the educational video. I tried this and it worked well in the beginning. Now the AC is working intermittently. Would you know the cause for that?

[@danielistratoaie3301]

Probably burnt out your compressor. The reason why they are inside the evaporator box is because they are set to work at certain temperatures. Once you put them in the cab the compressor over works and burns out or seizes.

[@MikkoRantalainen]

​@@letsgonow5641 Your system probably has too little refrigerant or the A/C pressure is too high. If the system hasn't been inspected during last few years, I'd get the refrigerant replaced. (The official way to adjust the refrigerant is to first suck everything out with a vacuum and then add vehicle specific amount in weight, usually 500 - 1000 g. Any pressure based method will be much worse.)
