The first generation RDX and the ZDX crossover share the 315MHz direct tyre pressure system used across Acura's 2007-2013 range, and both are now at the age where the original cells are exhausted. This OE replacement arrives pre-programmed with auto learn enabled, so the vehicle picks up the new sensor ID during the first drive cycle instead of asking the technician to enter it manually. Inside is a soldered lithium cell quoted at 5-7 years, a low standby drain circuit and a PPS housing rated to 125 Celsius degree, which matters on a turbocharged crossover where wheel and brake temperatures run higher than on a saloon. The sensor ships with a rubber snap-in stem and fixing screw, sealed to IP67, and every unit is pressure checked before packing.

Q: What does auto learn change in practice?
A: The sensor already carries a valid ID for the listed applications, and the receiver accepts it during a normal drive cycle. The fitter mounts it, inflates to the placard pressure and drives, with no ID entry and no tool.
Q: Does this fit the second generation RDX from 2013?
A: No. The 2013 and later RDX uses an indirect system with no sensor inside the wheel. This part covers the 2007-2012 turbo RDX and the ZDX only.
Q: Why quote battery life as a range rather than one figure?
A: Transmission frequency depends on how often the vehicle is driven and how much the pressure moves. A daily driven car usually sits at the lower end of the 5-7 year window, a low mileage weekend car at the upper end.
Q: What is the MOQ for a mixed RDX and ZDX order?
A: MOQ is 50 pieces, and both models can be mixed in one order. Stock ships in 5-7 working days, bulk production with OEM marking in 20-25 days.
Turbo crossovers from this era are inexpensive to keep on the road until a warning light turns into a dealer diagnostic bill. A pre-programmed 315MHz OE TPMS sensor with auto learn removes that step entirely, and the shared fitment across RDX and ZDX means one line item covers both.
