Bleve,
Sounds more like the Capts TAT probe (which feeds ADR 1 &3), the aircraft would then be no longer RVSM compliant (no autopilot). About a 30 min fix to change one over if the part is in stock.
Capt Kremin,
TAT not Pitot, the TAT is used to Mach number calculation and TAT indication on the lower ecam.
