My 2013 Toyota sienna's AC was not working on a hot day. After doing some research found that it could be the Air flow sensor problem. Verified by using a magnet on the existing bad sensor and AC started working. Since I did not want magnet to fall off while driving, ordered this particular item that was advertised as an exact match replacement.The part arrived quickly and I was able to disconnect the cable from the defective unit, which took the longest as it was in a very tight space, and connect to the newly ordered part. After the replacement, I tested the AC and it was as cold as it should be. Since it was difficult to remove the existing defective part, I left it alone. I just tucked this in with the zip tie.Provably saved me a lot of money by doing this myself.

Product came quickly from supplier. This part will save you huge money on repairs compared to dealer parts. Worth the money. 1/2 the cost from Napa.

This Dorman A/C Compressor Flow Sensor is a lifesaver! Toyota and Lexus don’t offer a separate OEM sensor, so finding this aftermarket option was fantastic. The sensor works perfectly and saved me from a much more expensive repair.Installation is straightforward, so you can replace it yourself without much hassle. If you’re looking to try a quick fix on your old sensor, I’ve found that placing a strong magnet next to it can sometimes get it working again. But if you want a reliable, long-term solution, this Dorman sensor is definitely the way to go!

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.

GRACIAS

Worked perfectly. Remove the engine covers, drain the rad 2" remove upper rad hose, air box inlet pipes, fan wiring, fan assembly, remove snap ring, break away sensor connectors. Use a torch low heat (propane) being careful not to burn all hoses and wiring. This breaks the glue and the sensor pulls right out. Clean the hole and pop the Dorman replacement back in. Reverse the procedure. Start the AC and heck the sight glass on the small high side, if you see bubbles you need a freon top up.Works perfect saves $ and needless waste.

This sensor stopped working on my car last year. I used a temporary fix for a little while but decided to fix it properly with this part. The workaround was to stick a rare-earth magnet on the left side of the sensor. This sensor uses a elctro-magnetic signal to tell the compressor to come on when the AC switch is on. These magnets seem to wear out over time causing the AC to no longer work. Im no mechanic but I can tackle most maintenance issues on cars. This part can be replaced without having to dismantle anything or drain any systems, depending on corrosion level on the compressor and skill it could be a 15 min job or take you a few hours.You should be able to replace this sensor on the car without taking it off, it helps if your disconnect the coolant overflow reservoir from the rad fans, just so you can move it out of the way, it doesn't need to be drained. The biggest issue i had was that the old sensor broke off when i was trying to remove it, the head of the sensor was still lodged inside its slot on the compressor. With a lot of time and some long handled/sharp standard-head screwdrivers i was able to break away at it enough that it came out. There is a snap ring that holds the sensor in place; getting this off/on was a little challenging as well due to the limited space to work in. Snap ring pliers are required. This sensor does not come with snap ring so dont lose the one you have otherwise you'll need to buy some.Once the sensor was on and with a small R12a top up my AC is blowing cold and ready for summer again.

I was advised by the Toyota dealer that I needed a new a/c compressor. The error code said it was a flow sensor issue so I looked up this part and took my car to another mechanic shop. The sensor had to be broken off the compressor because it was glued on. New sensor was glued on and when compressor was recharged everything worked well. New compressor with labour $1800, repair part $67 labour and recharge $400Based on this I’d go for a second opinion if you get a flow sensor code and you’ve been told the compressor need to be replaced. I hope this helps other Toyota Camry owners.
