Acura TL TSX TPMS Sensor 315MHz 2004-2014 OE Replacement Rubber Valve Stem

Third and fourth generation TL, and both generations of TSX, share a 315MHz direct system with a valve mounted sensor in each wheel. That shared platform is why one OE replacement covers a decade of production, and why a workshop does not need three part numbers to service a customer's TL and their neighbour's TSX. This sensor is pre-programmed, so after fitting the technician runs a single OBD relearn and drives the car rather than programming a blank unit at the bench. The stem is a rubber snap-in type with a nickel plated core, the electronics are sealed to IP67, and the quoted battery life is 5-7 years. Each batch is leak tested and RF verified against the Acura protocol before packing, which is the difference between a fixed car and a comeback.

• One part number across TL and TSX for a full decade, which cuts dead stock at the counter.
• Pre-programmed, so the relearn is a menu step rather than a programming tool operation.
• 315MHz output verified against the Acura receiver protocol on a bench reader.
• IP67 sealed electronics with a potted PCB, rated from -40 to 125 Celsius degree.
• Rubber stem supplied fitted, so valve and sensor are renewed together and a slow leak is not left behind.

• Independent garages servicing TL and TSX saloons and the TSX Sport Wagon.
• Tyre retailers repairing wheels where the original sensor was damaged during removal.
• Used car dealers clearing a warning light before listing a TL or TSX.
• Export distributors serving North American and Middle East Acura parts demand.

Q: Do the TL and TSX really use the same sensor?
A: On the years listed they share the 315MHz valve mounted design, so one part number answers both. Always confirm the model year first, because the TLX that replaced the TL from 2015 uses an indirect system.

Q: Can I fit just one sensor and relearn?
A: Yes. A single position is a valid repair, and the relearn procedure is the same. On a car over eight years old, quoting all four is often cheaper than two visits.

Q: Does this need a programming tool?
A: No bench programming. After fitting, complete the relearn through an OBD TPMS tool or the vehicle menu, then drive 5-10 minutes above 25km/h so the receiver registers the new IDs.

Q: What is the MOQ and can you print our brand?
A: MOQ is 50 pieces. OEM laser marking and custom colour packaging are available from 500 pieces, with stock shipped in 5-7 working days.

A TL or TSX owner rarely knows the part number; they know the light is on. A pre-programmed 315MHz OE TPMS sensor lets the workshop answer that with one relearn and no programming tool, and the shared part number across both models keeps the counter simple.
