The TPMS warning light on my 2015 Silverado lit up and the panel indicates the left front tire is low. It shows a pressure of 28-29 pounds. Actual pressure is about 32-33. Did not change any tires and did not add air to any tire recently. I know nothing about these contraptions. Suggestions on where to start are appreciated. Thank you.

Time to either get your TPMS re calibrated or replace the TPMS monitor at that wheel.

Put air in your tire and the light will go off. Your manual gauge could be wrong.

 

I have like 8 different tire pressure gauges, none of the slide style read exactly the same. Bridgestone used to send us boxes of like 200 at a time when I worked for that shop. I'd break them or they'd blow apart all the time. More often than not they are sorta accurate but that's good enough.

When you check pressure in other tires, do they match on your hand held gauge?

Aired all 4 tires up to 35 and disconnected battery. Warning TPMS light is now out, but only one tire shows pressure (31). The other 3 on my display are just "dashes". My screen also insists it is January 1 and 35 degrees. It's been in the 90s here for days!!! I ran it about 8 miles but perhaps it requires more calibration to set everything. Am on my second display as the other one gave up the ghost about 2 years ago. Was out of warranty but luckily GM picked up the tab after alot of complaining. Hope I don't have another issue. Appreciate the comments and help.

I would do the battery disconnect again, but also turn the key on when disconnected.  
 

youill have to rest your clock and drive 5-10 miles and your thermometer will readjust.  You may need to visit a tire shop or the dealer and see if they will rescan your tpms   Def sounds a little off.

Thanks all. Everything working OK now except left front reading 28 psi and the others 31. I'm sure there is 35 in each one. Checked with my motorcycle tires which I keep real close and also a second gauge. Light is off which is the most important. Has anyone used the available on e bay tools which allow you to reset your TPMS?

I bought the Autel TPMS TS508.
I suggest one stay away from the cheap ones, JMO...

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
