A/C Flow Sensor Replacement TSE14C/TSE17C Fit for Toyota Camry 2012-2017 RAV4 2009-2012 Corolla Subaru Scion 2.5L

Inexpensive and it works perfectly.

You cannot buy the actual sensor. This is a 4.5v resistor to fool the system. With that being said, you don’t have to try to remove the old one. You can just unplug it and plug this one in. Then tie or tape it to the harness so it doesn’t get in the way.

I used a telescoping magnet tool to diagnose the bad a/c sensor on my RAV4. After the magnet helped to turn the a/c on, I then started the change. It was difficult, and I finally had to remove the radiator in order to get to this sensor mounted on the front side of the compressor. I also bought some snap ring pliers from Amazon, but they were not adequate for this task. I ended up buying another type of snap ring pliers from the auto parts store that retained the tips with set screws. I had to chisel the old sensor out, then cleaned the hole with sandpaper. I also had to use sandpaper to take a little off the sensor edges in order to get the new sensor into the recessed hole. After a few light taps, the sensor seated and the retaining snap ring went back in. The radiator went back in much faster than it came out. After everything was back together and new antifreeze was put in, I tested the system. The A/c started operating correctly after the sensor change was completed. Thumbs up for this sensor. Delivery was on time.

Works

dealer wants a new compressor to fix the problem with bad air flow sensor. the sensor is not sold separately. found this one on YOUTUBE with link to Amazon. so far so good and no costly repair to change out old compressor and install new one just to get this part
