Tpms light came on. Shop found nail. Shop can’t reset tpms light. It’s an Infiniti. Need dealer scan tool. Shop says sensor is “bad”. Coincidence tpms light came on and they found nail? ---

if the nail caused air to leak out, wouldn’t the TPMS light come on? Isn’t that what it is designed to do? and if the shop cannot reset due to not having the correct software, then I wouldn’t take their input on whether the sensor is bad or not. ---

Find a different tire shop or go to the dealer. ---

Every time tires are rotated, the tpms has to be reset. The shop has never had a problem. The Acura resets while driving and there is a manual procedure with the Pontiac, or use the device the shop does. ---

> [@Cavell](#): > > Coincidence tpms light came on and they found nail? Unless nail came in contact with tire pressure sensor, or nail caused low tire pressure, coincidence theory seems the most likely explanation. I’d guess rather than a faulty sensor, the sensor’s battery has discharged over time & voltage is too low now. Either way, requires sensor replacement. If you think sensor might still be good, no harm to try to re-initialize it with a dealership scan tool. Or put black tape over the warning light …lol .. ---

Black tape always works. As far as the sending unit, how old are they? My truck is a 2013, sources state sending unit lifespan is 6-10 years. Had new tires installed Nov 2023, had sensors replaced though the originals were still working. ---

It’s a 2020. Infiniti dealer reset it in 10mins. Pep boys are a bunch of knuckle dragging monkeys. ---

> [@Cavell](#): > > Pep boys are a bunch of knuckle dragging monkey Can’t speak to PB, never used them, but years ago I was having trouble w/Corolla idle, so stopped by a national chain auto repair place for advice. Without even looking, and without missing a beat, the tech said the engine was dirty and needed an internal cleaning ..engine flush would solve it … lol .. no charge, so no complaints, I got what I paid for! ---

I wonder if the warning light switched off before they arrived at the dealer; _". The low tire pressure warning light does_ _not automatically turn off when the tire_ _pressure is adjusted. After the tire is_ _inflated to the recommended pressure,_ _the vehicle must be driven at speeds_ _above 16 MPH (25 km/h) to activate the_ _TPMS and turn off the low tire pressure_ _warning light. Use a tire pressure gauge_ _to check the tire pressure."_ ---

Owner did drive 20 miles at 55 mph and light was still on. Dealer fixed it So, you are saying it will reset on its own when dash says go to dealer? Seems like you don’t know it all ![image](https://global.discourse-cdn.com/cartalk/original/3X/2/6/260d929b8ae966e449a3345cf6d7589a92ca43f7.jpeg) ---

> [@Cavell](#): > > So, you are saying it will reset on its own when dash says go to dealer? Should it read “Visit Discount Tire”? The tire pressure in the left rear tire is too high. We have an inflation station on the driveway for the attendants to handle these 10-minute problems, can’t dispatch the vehicle to a technician and get the vehicle in and out of the shop in 10 minutes. ---

> [@Cavell](#): > > So, you are saying it will reset on its own when dash says go to dealer? Might have if the pressure was set correctly. Yet the TPMS thinks 40psi. is a flat tire, so who knows. ---

> [@PvtPublic](#): > > TPMS thinks 40psi. is a flat tire, It does seem a little surprising for TPMS to draw that conclusion. Improved software-verification needed? . The manager of an avionics software business told me part of the job is agreeing to be the first passenger on the plane after the new software is installed …lol … ---

There are a limited number of warning messages. The correct conditions were not met to extinguish the flat tire message. ---

That’s not a real dash anyway. Just an edited illustration. ---
