315MHz OE TPMS Sensor Acura MDX 2007-2013 Rubber Valve Stem Direct Fit

The second generation MDX runs a 315MHz direct tyre pressure system with a battery powered sensor in each wheel, and those sensors are now old enough that a warning light at correct pressures is the normal failure rather than an exception. This OE replacement is pre-programmed for the MDX application, so a workshop swaps the sensor and stem, inflates to the placard figure and completes one OBD relearn instead of programming a blank unit. The housing is sealed to IP67, the valve is a rubber snap-in stem with a nickel plated core, and every batch is pressure cycled and checked on a bench reader against the Acura protocol. Because the MDX is a heavy three row SUV that often runs close to its load limit, the sensor is quoted at a 900kPa working ceiling rather than a passenger car figure.

• 315MHz protocol matched to the MDX receiver, so the new ID is accepted on the first drive cycle after the relearn.
• Pre-programmed, which keeps the job inside a normal service slot instead of a programming appointment.
• 900kPa working ceiling suits a loaded three row SUV without the reading sitting at the top of its scale.
• IP67 potting compound and a nickel plated valve core resist road salt and pressure washing.
• 5-7 year battery life from a soldered CR2450, matching the second tyre change on most MDX vehicles.

• Acura dealers and independent shops handling MDX tyre and wheel work.
• Family SUV owners clearing a warning light without a dealership booking.
• Used car preparation where a tyre pressure light would otherwise delay resale.
• Distributors supplying premium Japanese SUV parts to North America and the Gulf.
