TPMS shows "0" but pressure is Ok and sensor is working
 

Hello!

I have a Trailblazer 2007 LTZ 4x4. the light of the TPMS is steady On, with " low pressure" message, the Front Right tire Shows "0 psi", (the rest of the all 3 tires are ok) I checked the pressure and its ok... then month later i replaced the sensor at that tire with another one OEM. After installed and did the relearn process (definflating the 4 tires etc, and the horn sounded for the 4 tires) the problem is the same!, that tire shows "0". What can be the problem? please help!

Thank you!

I would switch the tire/wheel with the left front, relearn it and see if it follows, or stays at the RF location.

You may also have a code stored in the TPM. This isn't visible through your typical OBDII scanner. I use the Hyper Tough HT 200 from Wal-Mart to read all the modules. Great little device.

i did another relearn process, and the next day after driving 1 mile the problem was fixed!

Thank you!!
