Hi,

A week ago one of the tire pressures was not displaying on screen.
Went to costco to change it but they would not saying all 4 TPMS units are working - they had a wireless tool that they take close to each tire and sure enough there was a read on each...
Did the TPMS reset with a piece of wire (6x grounding) and now all 4 tires show stars - no read... The yellow tire pressure dash light is solid...

What's the fix here?

Thanks,

Tapping the ground 6x does not reset the system, but put it into ID register mode. You have to adjust the tire pressures as follows: LF-36 psi, RF-33 psi, RR-30 psi and LR-27 psi. Turn the key on and ground the TPMS diagnostic connector 6 times in 10 seconds to put into ID register mode. The TPMS warning light will flash steadily to indicate ID mode and then the vehicle must be driven over 25 MPH for several miles until the light goes solid, indicating the sensors have been registered. FYI, sometimes a weak sensor battery can create intermittent issues, especially when the weather is cold. Once the vehicle is driven and the air in the tire heats up, the sensor(s) can start working, again. Note: if one or more of the sensor batteries are weak or dead, the ID process may not complete.

Well i did the 6 time tap over and over but all i am getting is the dash light and the screen shows stars... Did about 10 miles on it no change...
Is there a tool to buy on amazon to plug in and see? I have an OBDII reader but the app on my phone does not show anything about TPMS or tire pressure...

You would need a scan tool that has TPMS capabilities. I use an Autel Maxicheck MX808 which can do that, as well as a number of other things including an all sytem code scan, data monitoring and graphing, idle air volume and steering wheel position relearning, etc. I paid $365 for that from Toolfetch.com with a discount code a couple of years ago. When working with TPMS systems, I also use a Kent-Moore trigger tool to activate the sensors; I paid $50 for that, but you can get similar tools for around $35 online. The tool will show if a sensor is registered and can put the TPMS system is register mode, as well as read codes and show live data (tire pressures) from the sensors. What is doesn't do is tell you if a sensor signal is weak or dead, but there are TPMS tools that can do that.

SMJ,

Thank you! I looked at the costs and decided that it is cheaper to pay Napa Autopro $70CDN and they made it all work. Not sure why the first TPMS malfunctioned... But it is working now.

Thank you!
