Setting The Pressure Threshold on your TPMS

[RichB]

I have had issues with my TPMS going off for no reason especially when it first gets cold. My TPMS goes off sometimes when all of my tire pressures are perfectly fine. When these issues happen it is because the threshold on one or more of the sensors needs to be adjusted. Here is how to adjust it.

1. Before you start your car, make sure your tires are at your cold pressure setting then start her up and take her out for a drive.

2. After the drive (must be at least a mile), park your car and make sure to leave it running for this entire process.

3. Deflate each tire by 10 psi within 30 seconds to start the training sequence.

4. Fill each tire back up to the operating pressure and have all four done within 2 minutes.
Note: The TPMS light will come on when your pressure drops 25% below the pressure you set.

5. Take the car out for a spin and enjoy your new thresholds.

Note: Before you perform these steps make sure that your TPMS is linked up with your ECU. To do this, follow the steps in your users manual that talk about installing a new TPMS sensor.

This works? That's pretty sweet

Is there a max pressure threshold that can be set? I've had a couple times in the summer during long highway speed drives when the light has gone on, and when I check pressures they are still equal, if not a little high

Edit: I would try this procedure and see if it helps.

my tpms just went on for no reason.. i tried to reset it but it didnt workout, i believe like u said its not linked to the ecu..but i really comfused how to set it?? would u like to help me out??

How to link the TPMS to the ECU is in the users manual but here's basically how you do it:

1. With the car off, turn the key to the on position (without starting the motor) for 30 seconds then turn the key back off

2. Wait 15 minutes

3. Start the engine and drive the car above 20 mph for 10 mins. (Yes this sounds ridiculous)

Notes:

For step 3, find a highway. It took me about a full day of commuting to work to finally get mine to register so be patient.

Thanks for help!!I will try this soon!!!

I made updates to this procedure. I found out about a key step to start the training process for each sensor. Steps 3 and 4 have changed. I also added step 5. Enjoy!
