TPMS light flashing

Underneath the steering wheel. Like all the way at the bottom of the plastic.

Just to make sure people know, this button just tells the truck to send a signal to the TPMS sensors so it knows that the same wheels were rotated into new positions. It helps look for them again if there was a TPMS issue.
It does NOT learn new sensors if you replace a sensor or get new wheels with different Tpms Sensors. You need techstream laptop or something like a handheld Autel TPMS reader/programmer to learn new sensors.

 

Actually the TPMS button sets the pressure set point, it will reset the tire pressure setpoint in techstream if you hold the button. Say your new tires fill to 36psi instead of 32psi. It will use this new pressure as the starting point for the measurement. Once its 10psi low from this new set point the light will come on.

 

You can take your truck to any known tire shop and they could tell you what sensor is bad, they can also replace and reprogram it.

If you have techstream you could find out which sensor it is also. Techstream does not show which sensor is for which tire, but all you need to do is let the air out of each tire and watch which one does not change in techstream. Once your find which tire it is you can replace the sensor and since you have techstream you can reprogram the new sensor also. Just make sure you get the code off the new sensor before it is installed, also write down the sensor codes that are programed into techstream minus the bad sensor. When you reprogram the sensors you have to do all of them at the same time.

 

Call your local Discount Tire for an appointment. The reset is down by the hood release, probably a little to the right. Download your manual.

 

Discount has a flat fee replacement for sensors $60. No programming charge BTW.
