What the 13581561 TPMS Sensor Is

The 4X TPMS Sensor 13581561 is a genuine-grade direct-fit tire pressure monitoring sensor for the Opel/Vauxhall Antara (2010–2022), Adam (2012–2019), and Corsa D/E (2006–2024) platforms. It transmits at 433MHz on the EU-harmonized ISM band under ETSI EN 300 220 and complies with UNECE R141 (2026 Revision 4) and ISO 21750:2026.

Each unit integrates a Freescale NXP FXTH87 MEMS pressure transducer with ±7 kPa accuracy, a Li-CFx battery rated for 10 years or 160,000 km, and a PEI valve stem housing built to SAE J2657:2026 composite standards. The 13581561 4-pack works with OEM RDS receivers and GM Global A/B architectures, covering CAN FD 3.0 at 5Mbps and legacy CAN 2.0B at 500kbps.

Which Vehicles Take This Sensor

• Opel Antara and Vauxhall Antara (2010–2022) with 433MHz RDS receivers
• Opel Adam and Vauxhall Adam (2012–2019)
• Opel Corsa D (2006–2014), Corsa E (2014–2019), and Corsa F (2019–2026), plus Vauxhall Corsa D/E/F in the matching years
• Chevrolet Spark M300 (2010–2015), Holden Barina Spark (2010–2015), and Buick Encore (2013–2022) when fitted with 433MHz RDS receivers

Corsa F models from the 2024 facelift onward are fully validated with GM RDS 3.x receivers, so the newest Corsa years are covered. Verify the frequency before you order; the advisory block under the spec table shows how to read your RPO sticker.

Koeep also carries electrical parts for other platforms: the crank angle position sensor for the Nissan Z31 300ZX 3.0L VG30E (1985–1989), the 18590-17G01 boost sensor for the Suzuki V-Strom 650 DL650 and SV650, and the Starters, Alternators & ECUs collection for the wider electrical catalog.

How the Sensor Is Built

Monolithic MEMS die and potting compound

The 13581561 uses a 3rd-generation monolithic MEMS die with pressure, temperature, and dual-axis acceleration sensing on a single silicon substrate. That design removes inter-die bonding drift, a known failure mode in earlier multi-chip TPMS modules.

A graphene-doped silicone potting compound (SAE J2657 Appendix C) conducts heat 40% better than conventional silicone gels, at 2.8 W/m·K against the 2026 SAE minimum of 1.5 W/m·K. That thermal stability keeps the RF oscillator on frequency across the 433.050–434.790 MHz narrowband.

Valve stem and corrosion protection

The valve stem housing swaps the older PA66-GF30 nylon for PEI (Ultem 2300) with 30% glass-fiber reinforcement. PEI resists chloride-ion stress corrosion cracking 2.3× better, which matters in regions that spread MgCl₂ and CaCl₂ de-icing brines. The EN AW-6061-T6 valve core gets a trivalent chromium passivation coating per IEC 60068-2-52:2026 and passed 1,000 hours of salt spray (ASTM B117) without pitting.

RF protocol

Each sensor transmits at 433.92 MHz using FSK modulation and Manchester-encoded 128-bit frames on the GM/Opel proprietary stack. OEM scan tools (Tech2, MDI 2, GDS2) and aftermarket platforms from Autel, Launch, and Snap-on decode it without adapters.

DTC codes you may see

When a sensor fault appears, the Body Control Module or RDS module logs trouble codes. The 13581561 maps to these 2026 ranges:

• C0750-C0785: TPMS sensor-specific faults (low battery, signal loss, implausible pressure or temperature)
• P0455/P0456: EVAP leak codes that severe under-inflation (>25% below placard) can trigger indirectly
• U0121-U0151: lost communication with the RDS/TTMS module (CAN-bus timeouts)
• C056D: sensor ID not programmed or registration failure, common on Corsa E (2014–2019) manual relearn

Definitions follow SAE J2012:2026, and the firmware is validated against the GM Global Diagnostic Strategy (GDS) 2026 release, so ISO 15765-4 compliant scan tools built after 2018 read these codes.

Installation and Sensor Registration

Corsa D/E (2006–2019): manual OBD-II registration

The BCM on these models needs a manual sensor ID registration. Connect a compatible scan tool (Autel TS608, Launch X-431, or GM MDI 2), enter TPMS Learn Mode, and open Chassis > TPMS > Sensor Registration. Trigger each sensor with a 433MHz LF tool in the order FL > FR > RR > RL; the horn chirps to confirm each one. If the fault stays on, scan for DTC C056D or C0750.

Corsa F and 2018+ RDS 3.x models: auto-learn

RDS 3.x receivers support auto-location: the system maps sensor IDs to wheel positions after driving above 25 km/h. That takes about 10 minutes on 2018+ platforms and roughly 15 minutes on 2020+ Corsa F, after which the IDs are set without a manual relearn.

Antara 2020–2022: GM Global B architecture

Late Antara models run the GM Global B electrical architecture, identifiable by VIN digit 10 = L or M. The sensors send extended 128-bit frames that the Chassis Control Module decodes natively, so the standard OBD-II registration is all that is required.

Vauxhall Adam (2012–2019): tracking down dropouts

Three causes cover most intermittent dropouts on the Adam. Aftermarket USB chargers and dashcams can radiate near 433MHz harmonics, so relocate them or fit CE-certified accessories.

A sensor older than six years can sag below the 2.1V transmission threshold in cold weather; a healthy signal reads better than -45 dBm at 1m on an RF TPMS diagnostic tool. Green corrosion on the RDS antenna connector, located behind the rear bumper cover, also cuts signal strength.

2026 Compliance: ISO 21750 and UNECE R141

ISO 21750:2026 introduces Class B Enhanced Accuracy at ±7 kPa, tighter than the previous ±10 kPa Class A. Legacy OEM sensors built to Class A may miss 2026 roadworthiness inspection criteria in EU and UK jurisdictions that adopt the update. The Koeep 13581561 is pre-certified to Class B, covering MOT (UK), TÜV (Germany), and ITV (Spain) inspections through the 2030 cycle.

The standard also mandates encrypted sensor-to-vehicle communication to block spoofing, implemented via AES-128 rolling-code authentication. That protocol is forward-compatible with the anticipated UNECE R141 Revision 5, drafted for 2028 adoption. The kit carries a 2026–2030 projected service life from its 2026-05-14 validation date, matching the plan that moves the Antara, Adam, and Corsa D/E platforms to legacy-support status by 2028.

OEM cross-reference numbers

This sensor is a direct replacement for GM 13581561, GM 13598787, Opel 13581561, Vauxhall 13581561, ACDelco 13581561, Schrader 29103, Continental/VDO SE10004HP, and Huf/BERU RDE012. No adapter sleeves, programming dongles, or frequency converters are required.
