It’s likely that your car has a TPMS, or tire pressure monitoring system, if it’s a new or recent model Nissan. This computerized technology keeps track of the tire pressure in your automobile and notifies you when it deviates from the ideal range. Nissan vehicles come equipped with TPMS systems that are intended to improve your on-road security while also maximizing your vehicle’s fuel economy and handling capabilities.
Look for a “low tire pressure” warning light that turns on in the instrument cluster when the key or push-button start system is in the “on” position if you’re unsure whether your Nissan has a tire pressure monitoring system (engine not started).

2007–2019 NISSAN ALTIMA
All American-made automobiles must have direct or indirect TPMS systems fitted as of 2008 as a result of the TREAD Act’s 2007 mandate.
The Nissan Altima employs a direct TPMS system, which means that the wheels themselves are home to the TPMS sensors. The TPMS sensors will send information to the vehicle’s ECU if one or more tires show low tire pressure. Each tire pressure or an indicator light (low-line TPMS system) will be displayed on the dashboard (high-line TPMS system).
A TPMS relearn is advised to write the new sensor IDs to the vehicle’s ECU when a tire is changed in one or more Nissan Altima tires.
What Does the Tire Pressure Warning Light on a Nissan Altima Mean?
What does it signify if your Nissan Altima’s TPMS tire pressure warning light is on?
You should check your tire pressure using a basic pressure gauge for around five minutes since it indicates that the actual tire pressure is either too high or too low.
monitoring the function or performance of each tire by regularly checking its pressure in order to execute timely and appropriate repair.
Keep an eye on the warning light that says “Low Tire Pressure” or “High Tire Pressure” on the dashboard; it’s a useful tool for alerting you to high or low tire pressure.
After removing the valve cap, tap the metal pin inside with your fingernail or a flat-head screwdriver to hear a hissing sound. Deflate it until the appropriate PSI is reached.
You will, however, typically see low tire pressure. A leak, a small puncture, or a fast change in temperature could be to blame for the problem. If so, scroll down to find out how to handle it.
How can I fix my Nissan Altima’s TPMS?
When the tire pressure light blinks three times, release pressure on the TPMS reset button. Start the car and let it run for 20 minutes to let the sensor reset. Under the steering wheel is typically where you’ll find the reset button for the tire pressure monitor. Check the owner’s manual for your vehicle if you can’t find it.
AutoZone is able to check TPMS sensors.
You can determine if your tire pressure monitoring system is corroding or failing within your wheel with routine inspection; if so, you will need to replace it. For your repair, AutoZone carries every tire pressure monitoring system item you’ll need, enabling you to drive again efficiently and safely.
Is my car safe to drive with the TPMS light on?
To avoid seeming like Debbie Downer, we’ll simply say no. Driving around with your TPMS light on is not safe. You can’t tell how quickly your tire is losing air or how long it has been over- or underinflated without doing a tire examination. The best course of action is to check the current inflation level of each tire with a tire pressure gauge.
When the tire inspection light appears while you are driving, slow down and get to the closest gas station or service facility.
What distinguishes TPMS from low tire pressure?
A tire pressure monitoring system (TPMS) is built into your car and is intended to monitor the air pressure in each tire. The Low Tire Pressure indicator on your dash goes on automatically when the system detects a low tire (it looks like a tire with an exclamation point in it). Until the tires are checked and the pressure is adjusted, this light will remain on.
On the other hand, the TPMS light is intended to turn on when there is an issue with the monitoring system itself. For instance, if a sensor in a wheel malfunctions, the TPMS light will illuminate and remain on until the issue has been resolved.
The maintenance process is not replaced by the TPMS system. Even if the indicator is not on, you should physically check your tire pressure at least once every month.

How does the TPMS identify each tire?
The anti-lock brake system’s wheel speed sensors are often used by an indirect TPMS. On-board computer systems can employ these sensors to compare wheel revolution rates between individual wheels as well as to other vehicle operation data, such as speed.
The computer can determine the relative size of the tires on your car based on how quickly each wheel rotates. The computer determines that a tire is underinflated when a wheel starts spinning more quickly than normal and warns the driver accordingly.
So a system that monitors tire pressure indirectly does not genuinely detect tire pressure. The same kind of measurement you may observe with a tire gauge is not being processed electronically. An indirect tire pressure monitor only counts the rotational speed of your tires and sends instructions to the computer to activate the indication light when something seems off with the rotation.
What occurs if TPMS sensors are not replaced?
Customers who ask you to turn off their TPMS light just and leave the underlying problem unattended can put you and your business at unnecessary risk. Without addressing the problem, you are breaking the NHTSA’s “make inoperative” clause, which makes shops legally obligated to disable the TPMS. It is your duty to let the customer know this and to decline service if they don’t want the problem handled properly.
It is strongly advised to replace all sensors at once if a single sensor has reached the end of its useful life. When one sensor fails, the others are likely to follow suit quickly, just like with headlights. The same holds true for replacing an impact sensor or damaged valve stem. Your consumers should be aware of this since it will assist you give their vehicle the finest care possible. They also find it convenient.
The TPMS sensors must always be reactivated and calibrated for drivers who change their tires as the seasons change. If you don’t do this, the car’s TPMS won’t function properly and could turn on the TPMS light.
Is TPMS on the tire or rim?
When the air pressure within the tire lowers, your car’s tire pressure monitoring system (TPMS) will sound an alarm and notify the driver. This is an electronic system that links the monitor on the dashboard of the car with the sensor that is mounted on the rim to display whether the tires are adequately inflated or not.
The TPMS will alert the driver with a flat tire warning light if the tire starts to lose air pressure. This indicates that the tire’s proper inflation level is not being maintained for whatever reason; whether as a result of tire or valve damage, the tire will need to be reinflated and repaired.
These sensors make sure the tires don’t deflate to dangerously low levels, which, if one is not careful, could further harm the tire, the rim, and even the TMPS unit. Due to this, they have been a necessary component of automobile production in the US since 2008.
The service life of tires will be shortened by rapid tread wear caused by improper tire inflation. Lower inflation extends their footprint, endangering their ability to drive safely and increasing pressure buildup while they perform, which will destroy their ability to use gasoline efficiently. The tires’ wet weather performance will also suffer from the broader footprint, which will also lengthen the distance between stops. In other words, it will harm the car’s performance and safety when driving.
How inflated should a Nissan Altima tire be?
Are you concerned about your Nissan Altima’s tire pressure? Perhaps your low-pressure indicator lit up, but you are unsure of how much air your tires require. We looked into the matter, and the following is what we learned.
Tire pressure for your Nissan Altima should be 32 PSI. The majority of year models share the same number. Additionally, it is unaffected by the size of the tires.
You must understand how to check the levels now that you are aware of the recommended tire pressure. Continue reading to learn how to check the air in your tires, how often to check it, whether you can drive with low air pressure, and other topics.

Can I change the TPMS sensors on my own?
The Tire Pressure Monitoring System, which notifies you when a tire is dangerously low on air, typically uses TPMS sensors embedded in the tires to detect low tire pressure. The majority of TPMS sensors use internal batteries that cannot be changed to power them.
The lithium ion batteries in a TPMS sensor have a lifespan of 5 to 10 years. The duration of the TPMS sensor batteries is difficult to predict because it depends on how many radio frequency broadcasts the sensors send out. The amount of driving you perform over time and the conditions you drive in will affect the sensor battery life. The TPMS battery life is less affected by cold conditions than by warmer ones. When compared to continuous pace, stop-and-go traffic has a greater effect on TPMS battery life. This is due to the fact that sensors send out more radio frequency broadcasts as a vehicle changes its speed.
The system will issue a malfunction warning when a TPMS sensor’s battery runs out, which will be visible as a blinking TPMS light on your dashboard. After 60 to 90 seconds, the light may either continue to flash or turn solid. Be a repair appointment as soon as you can if you receive this warning, but also check the tire pressure in each tire right away to make sure you have safe inflation all around.
You can change each individual TPMS sensor separately if one of them malfunctions and needs to be replaced. The other sensors, on the other hand, are probably on the verge of failing as well if the failure was brought on by a dead sensor battery. You might wish to proactively replace all the sensors so you have brand-new sensor batteries all around when you take into account the time and hassle of taking your car off for a sensor replacement.
Is it a cause for concern if my TPMS light is on?
The TPMS (Tire Pressure Monitoring System) is designed to notify you when a tire’s pressure is too low and may result in hazardous driving situations. If the indicator is on, your tires may not be properly inflated, which might result in premature tire wear and even tire failure. It’s critical to comprehend the value of appropriate tire inflation and how TPMS can prevent a potentially hazardous situation.
Both excessive and inadequate tire inflation can result in early tread deterioration and potential tire failure. Increased traction, early wear, and an inability to withstand impact from the road can all be effects of overinflation. The middle of the tread on tires with excessive air pressure may prematurely wear out. Underinflation, on the other hand, results in slow tire reaction, lower fuel economy, excessive heat buildup, and tire overload. The shoulders or tread edges of a tire that is underinflated will prematurely wear out on both sides.
Finding the TPMS indicator on your dashboard is straightforward if this is your first time hearing about tire pressure sensors. It is a light that has a horseshoe form with an exclamation point in the middle.
