We had a 2012 Aston Martin V8 Vantage in the shop for a TPMS "Tire System Fault" message on the dashboard. The car had been showing the message for about a year but the sensors were reading fine on the dashboard. When the pressure changed, the screen would show the correct change in pressure so the dealer didn't recommend changing sensors as a resolution. We also scanned the sensors with our TPMS programming tools and both tools read the pressure as good and battery condition as "ok". So we were also skeptical on whether new sensors would resolve it.
Online we saw that other Aston Martin owners had bypassed the TPMS but found this to have mixed results. Afterwards, we used our OBD scan tool and connected it to the OBD module on the passenger side we cleared the DTCs and four DTCs remained, all regarding the sensor voltage supply being low. At that point we knew that the sensors needed to be replaced to get rid of the warning light. The original BERU sensors were about 10 years old at this point and was about the right age for the batteries to go bad. TPMS batteries are sealed and are not serviceable but aftermarket replacement units are not too expensive.
Our universal programmable sensors worked, which is a pro-tip for those that have this issue as the sensors needed are just generic units and most tire shops will have these on hand. They are the same sensors we would use on a Toyota Camry so they are not an exotic or overpriced part that you may find elsewhere on an Aston Martin. For this car we used the Max Select series of sensors, but we also tried the Autel MX sensors which were compatible as well.
We would expect to see this issue on similar models like the Vanquish, DB9, and DB11 where the sensor still functions perfectly but the TPMS fault is showing. Most cars don't show an error until
