Dorman 926-818 Air Conditioning Compressor Flow Sensor Compatible with Select Lexus/Scion/Toyota Models (OE FIX)

Great fit. AC is cold again. To check and see if this part is needed all one has to do is start your Camry up w/ac on and place an extended magnet on the sensor. If the ac fan and compressor fans cut on, it is the issue. YouTube helped. I had to remove my upper radiator hose and carefully move old sensor back and forth to remove.

Exact replacement for A/C Flow Sensor. I didn't actually remove the bad sensor, I just unplugged the sensor wiring harness and plugged the connector onto the replacement Dorman sensor. I then used a zip tie to secure the Dorman replacement sensor onto the alternator's wiring harness. I did not have a solid failure like most folks who reported here. I had the more obsure intermittant failure to energise the A/C clutch. Sometimes it would come on and other times it would not, which caused the windshield to fog up on humid days, always when my wife was driving. It never got really cold, just cool, when it would come on at all.Before starting, I'd recommend doing a search for you tube videos on replacing A/C flow sensor on your year and model. Watch a few of the videos to get a better idea of what you're getting into, and where everything is located. Not impossible, the sensor is difficult to access, but you don't have to remove as many parts as some of the videos might recommend.Let's say it wasn't quite as simple as unplugging, replugging and zip tieing. The connector is very difficult to access and what I did is the minimum required to get the A/C working properly again. Everything was done from the top of the engine. No need to go underneath for my 2011 Sienna.What I did to get the new Dorman sensor plugged onto the flow sensor's connector is as follows...I started by removing the negative battery terminal and securing it away from the battery post. Then I removed the large lug on the alternator and fastened it back out of the way. Then I unplugged the alternator's wiring harness plug and positioned it back out of the way. Then I had better access to the A/C flow sensor connector. I used two long screwdrivers, one to push down on the sensor connector release tab and the other to pry down on the connector, first one side, then the other, gradually working the connector loose. At that point it was a matter of plugging in the Dorman replacement sensor until it latched into place, and zip tieing it to the alternator wiring harness. I left the old disconnected defective sensor attached there on the side of the A/C compressor. Then it was a matter of buttoning everything up... replace the large lug, nut, and lug cover on the alternator, and reconnecting the alternator wiring harness plug. Finally reconnected the negative battery cable. Took a test drive with the ouside temperature at 75 degrees, and varied the temperature control from MAXcool to 80 degrees which cycled the A/C on and off. It consistently cycled on and off with each change. On the MAX cool setting I was frozen out of the van in about a mile. Hasn't worked this well since last year. So far, so good. Highly recommend this Dorman flow sensor. If it fixes your A/C problem it's $25 instead of $1000 or what ever you would pay to have the compressor changed out. I'll bet on those odds every time.

The sensor is a replacement for one that is mounted on the compressor. This is the only part you can purchase that I found that remedy’s the A/C on a Toyota not working.Some people bypass the sensor by putting a magnet on the old sensor or purchase this one.So from what I understand Toyota only sells the Compressor and the sensor as one unit and If the sensor is bad then their fix is to evacuate the Freon and replace the compressor,This will cost well over $1,000 with parts and labor.Here is the tricky part, it is a real pain to remove the old one and it is not because of the snap ring(although that was a pain also).It is a pain because some sensors like mine were glued to the compressor and you will have to chip away at it with a hammer and long screwdriver in a tight space to remove most of the old sensor and to clean up the remaining sensor out of the cavity I used a 90 degree dremel (I found the 90 worked well). Just be careful not to pierce a hole in the compressor or hit a wire.With some time, patience and a good flashlight you should be good.I did not place the snap ring back on, Instead I used high temp stove caulk on the outside of the sensor to hold it in place. I have read some comments that some people just plug the new one in and let it hang and abandon the old sensor in the compressor and everything works well from what they said.
