Having a modern Saab 9-5 with sensors that will notify you about every little issue is a great thing, but it can also be annoying because some of these errors need to be cleared by a Tech 2 scanner. Case in point the TPMS sensors. It is unbelievably helpful, especially if you aren’t used to checking your tires regularly before going on a trip.
On the other hand, if you live up north where winters are nothing to joke about, you’ll need to switch your summer tires for winter tires at least once a year. Even if you have OEM TPMS sensors on both sets of wheels, your car will present an error message that it can’t read the pressure in the tires once you switch between sets.

How do TPMS Sensors Work?
A tire pressure monitoring system or TPMS uses a set of sensors to monitor the tire pressure in all your wheels. It can use direct sensors that are placed in the wheels or indirect sensors that measure the wheel speed on each corner of the car, notifying the driver that one of the tires is spinning at a different speed.
The sensors within the wheels are a better option because they monitor tire pressure directly instead of relying on other factors.
These sensors have an important role because adequate tire pressure reduces braking distance, eliminates uneven tire wear, and improves handling amongst other things.
If you have a Saab 9-5, here’s a step-by-step guide on how to program the TPMS sensors without using the Tech 2 scanner.
Programming TPMS Sensors On A NG9-5 Without A Tech 2 Scanner
Not only does a trip to the dealership include scheduling an appointment, but every single piece of work on your car costs money, no matter how simple the process is. If you don’t want to spend time and money resetting the TPMS sensors every time you replace your summer wheels for winter ones, here’s what you need to do.
Step 1 – Start Your Car And Put It In Parking Brake
This is a pretty simple and straightforward process. The only thing you should be aware of is that you need to park your car on a flat surface.
At this point, you should clear all notifications or warning messages, and enter the vehicle information menu. You can do this by using the left control stalk next to your steering wheel.
Step 2 – Enter The Tire Pressure Settings
Once all the messages have been cleared, you need to navigate to the tire pressure settings by using the control stalk on the left side of the steering wheel. Instead of pressing the button on the left stalk quickly, you should press and hold for a couple of seconds.
Step 3 – Are You Sure You Want To Relearn?
Once you hold the end button on the left stark, the message “are you sure you want to relearn” will appear on your dash. Navigate to “yes” and press the end button again. Your horn should beep twice if everything is done correctly.
Step 4 – Deflate The Tires Considerably
After hearing the horn beep twice, you have two minutes to get what you need and start deflating the tires. You’ll have 5 minutes after you start deflating to go through all the tires. After you remove around 30% of air from each tire, the car will beep its horn letting you know that you can move on to the next tire.
Start from the front driver side and move around the car following the indicators as they light up. The order should be front driver’s side, front passenger side, rear passenger side, rear driver side.
Step 5 – Inflate The Tires To Factory Specs
After you’ve deflated the tires, they should be inflated back up to factory specifications. Keep in mind that you have only 5 minutes to complete the process which means you’ll need to have a compressor with a precise gauge, so you can quickly and easily inflate the tires accordingly. After you inflate the tires, the process is done.
