The five generations of the Nissan Altima present drivers with a flashy, mid-sized vehicle that is just as reliable as it is fun to drive, but on the dashboard, the wide collection of check and warning lights and other technical specifications can seem a little confounding. One particular problem that seems to cause drivers the most trouble occurs with the Nissan Altima tire pressure monitor, as when there is a malfunction within the Tire Pressure Monitoring System (TPMS) of the Nissan Altima or the vehicle simply has low pressure in its tires, drivers are greeted with the low-pressure warning light. Getting this light to turn off can be a little tricky, but with a few specific tools and an ability to navigate the TPMS system, drivers with no mechanical experience whatsoever can reset their Altima tire pressure monitor.

Resetting the Nissan Altima TPMS
When the telltale light comes on and indicates under-inflated Nissan Altima tires, drivers should stop the car as soon as possible and adjust the tire pressure on all four tires using a tire pressure gauge. The proper pressure for these tires varies between different Altima models, and to find the specific numbers, drivers can check the recommended cold tire pressure shown on the Tire Load and Information label located on the driver door opening. After drivers inflate their tires, they must then drive their Altima at speeds above 16 mph to activate the TPMS. If there are no further problems, the telltale light should simply turn off.
Methods of Resetting Tire Pressure Monitor Malfunctions
Malfunctions within the TPMS system can be much more difficult to reset, and according to the Nissan Altima owner's manual, this situation recommends that drivers take their Altima into a Nissan dealer for a check-up. However, with a little understanding of the various parts associated with a Nissan TPMS system, amateur mechanics can easily reset their system by programming the TPMS sensor identifications with the different sensor monitors on all tires. For this procedure, drivers need to use a Nissan scan tool or equivalent model, as well as a J-45295 activation tool.
Sensor Wake Up Procedure
After replacing Nissan Altima tires or adding new sensors to the tires, the first step in resetting the TPMS is to wake up the wheel sensor. To start, simply turn the ignition to the 'ON' position and push the transmitter activation tool against one of the tires. Then, press and hold the activation button for around 5 seconds and the hazard lamps should flash, indicating a sensor ID registration into the TPMS. Repeat this for the left front, right front, right rear, and left rear tires, in that specific order, and after the vehicle has assigned the sensor IDs for all tires, the hazard lights should flash again. Drivers should then drive the vehicle at speeds faster than 16 mph to verify that the low-pressure warning light turns off.
Sensor Reprogramming
If the low-pressure warning light is still on after adding tire pressure and completing the sensor wake up procedure, it is important to undertake a sensor reprogramming procedure. Fortunately, drivers can reprogram their sensors with or without the J-45295 activation tool, but each procedure requires the Nissan scan tool or equivalent.
Steps | With Activation Tool | Without Activation Tool |
Step 1 | Connect scan tool to vehicle diagnostic connector | Connect scan tool to vehicle diagnostic connector |
Step 2 | Select BCM function on the system select screen | Select BCM function on the system select screen |
Step 3 | Select Air Pressure Monitor on Select Test Item screen | Select Air Pressure Monitor on Select Test Item screen |
Step 4 | Select Work Support on Select Diag Mode screen Select ID Regist | Select Work Support on Select Diag Mode screen Select ID Regist |
Step 5 | Place transmitter activator against the front-left tire near the sensor Hold activator button for 5 seconds | Adjust tire pressure to specific values Front-left at 36psi Front-right at 33psi Rear-right at 30psi Rear-left at 27psi Drive at speeds faster than 25 mph for at least 5 minutes |
Step 6 | Repeat for front-left, front-right, rear-right, and rear-left tires | Press End to complete procedure |
Step 7 | Press End to complete | Inflate tires to Nissan Altima specifications |
After reprogramming the sensor IDs on all four tires, the tire pressure monitor should be reset. However, if the warning light is still on, drivers have no other choice than to visit their local Nissan dealer.
How to Buy Nissan Altima Accessories on eBay
Driving on low-pressure tires can be a potentially dangerous situation, and whether the low-pressure light is on because the tires are low or because the TPMS is malfunctioning, getting this light to turn off is certainly an accomplishment. Fortunately, when you are looking for transmitter activation tools, tires, and any other Nissan Altima accessories, you can find everything you need from sellers near you on eBay. To search effectively on the site, locate the search bar found on every page and enter keywords specific to the Altima accessories you want. However, when browsing among potential accessories, always read the product descriptions thoroughly and make sure that the accessory is compatible with your Altima model. You can increase your vehicle safety while making sure that your TPMS is in always working condition by effectively resetting the tire pressure monitor on your Nissan Altima.
Sensors are easily overlooked. These small components are much more important than you might think because they make the features you use most often on your smartphone possible, and they can even save battery life. So, you'll want to keep your smartphone's sensors in good working order. In this article, we show you how to do just that by calibrating them.

Check to see if your sensors are working
Test the problem across multiple apps
Sensors are vital for many of the basic functions on your phone, but they’re known to stop working the way they should from time to time. Before deciding if it's broken and taking it in for repair, you should try to calibrate it.
Sometimes, you'll notice the problem when an app that uses a particular sensor isn't interpreting the data correctly. In order to find out if that's the case, the only thing you have to do is download a different app that uses the same sensor and try it out.
For example, if you're playing a racing game and the car doesn't respond to your movements, try it in another racing game to see if the problem persists, or if it's just a game bug or poor programming. If the problem persists no matter which app you're using, that suggests an issue with the motion sensor of your smartphone.
It's not just motion sensors that can start to malfunction for no apparent reason. Problems with other sensors can also lead to poor battery life. For example, the proximity sensor saves power by turning the display off while you're talking on the phone, and your smartphone also uses a sensor to measure ambient light and adjust the display brightness accordingly.
Use a diagnostic app
Diagnosing whether an issue comes from a sensor isn't always as easy as trying to replicate the problem on another app. On occasion, you'll need to use one of the following specialized apps to dive into the depths of your smartphone in order to check if the sensors are taking measurements: Sensors Multitool.
Sensors MultitoolIn some cases, like in Sony's Xperia devices, phones come with a diagnostic tool. You can find it by going to Settings > About phone > Diagnostic, or just open the app from the app drawer. If you go to the Test tab, you can check the performance of each sensor separately or do a complete diagnostic test.
Use hidden menus and secret codes
For those devices that don’t come with their own diagnostics features, there is an option to test sensor performance within the hidden menus. To access them, you'll need to go the phone dialer and put in a certain number combination. Android has secret codes to access each of its hidden settings, but there are some codes which change according to the manufacturer. You can test the performance of your sensors as well as other features like the camera, the display or the audio in different diagnostic modes.
Here are some examples. We have the code, *#*#4636#*#* in order to access status information about multiple components and usage statistics. For Xperia devices, we also have this code, *#*#7378423#*#*, which during Service tests, you'll be able to check if on-screen items are working properly. To find the code you need, simply check out our full list of Android secret codes.
Calibrating sensors
There are a lot of reasons you might want to calibrate your phone's sensors. It might not be necessary, but you want to make sure that everything is calibrated perfectly. Or maybe something's not working properly, and you'd like to run this feature to see whether it's broken or not. Whatever your reason, some of your sensors can be calibrated, although how you can go about doing it depends as much on your particular model of smartphone as it does on Google Play.
Use built-in calibration features
Some brands have built-in calibration options for particular sensors. For example, on some LG devices, starting with LG G2, you can calibrate the motion sensor by going to Settings > General tab > Motion. All you need to do is follow the directions and in a matter of seconds, your sensor will be calibrated. To find out if your smartphone has similar options, just type a quick search for the name of the sensor in your phone's Settings menu.
Use an app from the Play Store
Some brands don't let you calibrate all the sensors though, like Sony, so in this case, it would be better to jump onto the Play Store and find an app that can recalibrate the particular sensor that you're trying to fix or give a little tune-up. There are a ton of highly rated, free apps for various sensors like Accelerometer Calibration Free, Quick TuneUp-Phone Calibration, Proximity Sensor Reset and Compass Direction Optimizer - Gyroscope Tester.
Factory reset
If there isn't an app available, there is another, more drastic way to do it. Resetting your phone to factory settings will normally recalibrate all the sensors automatically. Obviously, you have to backup everything before you do a factory reset, because you'll lose all your data!
Rooted phones have more options
Root users with cooked ROMs, Xposed modules and other apps for this type of user have even more options to personalize and control the sensors on their smartphones. For example, the aggressive Proximity Sensor Fixer app, which only works if you've rooted your phone.
However you diagnose and calibrate your phone, share your methods with us below! Do you use a third-party app? Does your custom ROM include a calibration option?
