The battery in the sensor last about 5 years. If your car is about 5 years old and you plan on keeping it, order all four sensors. You car should tell you on you dashboard information screen. It will not display a pressure for the sensors that are bad.

You only need the one that's not working. If you have 3 pressures, replace the one that is not showing

It should be on the display which tire is causing the problems, or which tires. If not, buy one and get it installed, see if this clears up the problem.

your vehickle will tell you how many you need . I always have at least 2 backups because tire centers charge alot for them

You need to take your vehicle to a shop or tire store and ask them to read your sensors. If they will not read,then it is bad.

That is quite a silly question..of course if you have one set of brake pads and there's a left and right side, then QUITE OBVIOUSLY it will come with two sensors! Cheers.

I used only one of them, which I used on the cpu cooler. There are option to have the fans automatic or manual. If maual you done need the sensors.

Google the sensor and display to find the instructions. I seem to recall that there's a jumper on the circuit board that you need to set for one or two temp sensors. So I'd take a look at the docs before I gave up.

They make a light for this and I believe you need 2 of them. One for each sensor.

Single sensor, but they worked flawlessly. Well worth it, 2 years and no issues.

this one does only have 2 sensors included not sure how many inputs. I had an installer put it in, I do recall him saying you could add more stuff to it just not sure what all could be added. I do love this system though. Wish I had done it years ago.

Single sensor. Put mine in about 2-3 years ago and no issues since. Took approx 1 hr for me and a friend to change in the driveway. Mine were rusted pretty severely. Biggest issue was getting the wiring disconnected without breaking the connectors.

2 sensors came in the box. I actually need 2 sensors and ordered 2 boxes by mistake. Returned the second one.

Of course they are two sensors, as they pick up signals from two different areas, the crank and the wheel. I bought my late 2014. It is the best cyclcomputer I own.

If I understand your question, you want one sensor to turn on a light and a second sensor to turn it back off. The answer would be "NO". These sensors do not have three-way capability.

These sensors should work with units that have 2 wire connections to the main system board. They are quite simple and work very well. You should not have any trouble replacing your old, damaged, non-working sensors.

Hi, thanks for the question. Unfortunately the W403 is sold with only 4 sensors and can only program 4 sensors at a time as well. Thanks!

You do not need to purchase two. If your system only has one sensor that's all you need. In my case, the water sensor failed and this item replaced it perfectly. My system's original air sensor is still working fine and I expect it will for a long time as it is sheltered from the elements.

I use one sensor and it alerts me in 2 locations on my property, Bugs running across it can set it off. Needs some light to make it work too.

Yes, one sensor in a pack. They need to be "triggered" and the car needs to be programmed for the new sensors. I recommend taking a picture of the serial numbers on each sensor before installing them.

The one I purchased came with two sensors. And they work WONDERFULLY!!! I bought two more, and added them. These little detectors are great. They are sensitive, too (placement is key).
