Essential Specs & 2026 Compliance

The Koeep 2-Piece Camshaft & Crankshaft Position Sensor Kit (1800442 / 1800441) is precision-engineered for the 2026 Mazda MX-5 Miata ND3 with the Skyactiv-G 2.0L inline-4 engine, as well as backward-compatible with Mazda 323 (BJ), Demio (DY), and earlier MX-5 NA/NB/NC platforms. These sensors employ Hall-Effect magnetoresistive sensing technology compliant with SAE J2716 SENT digital protocol and ISO 27145 (WWH-OBD) global diagnostic standards mandated for 2026–2030 model-year vehicles. Designed to interface seamlessly with the MX-5's CAN-bus 3.0 architecture (ISO 11898-1:2024), the kit meets ISO/SAE 21434 cybersecurity requirements for ECU-integrated sensor networks. Each unit is factory-calibrated to OEM tolerance windows of ±0.5° crankshaft angular resolution, ensuring precise ignition timing and variable valve timing (VVT) actuation across the full 7,200 RPM operating range.

• Is it compatible with 2026 CAN-bus 3.0? — Yes; SENT-protocol digital output ensures zero-signal-loss transmission to the PCM over ISO 11898-1:2024 networks.
• Does it support 2026 Mazda MX-5 ND3 specifically? — Absolutely. Cross-references OEM part numbers PE01-18-221, BP4W-18-221A, ZL01-18-221A, and J5T27071/J5T27072.
• What DTC codes does this sensor kit resolve? — P0335, P0340, P0344, P0365, P0369, and associated P0011/P0012 VVT correlation faults.
• What is the projected service life? — 2026–2030 duty cycle; rated for 100,000+ miles with high-temp composite housing resisting thermal degradation up to 180°C (356°F).
• Is this plug-and-play? — Yes; OE-identical connector pinout with gold-plated terminals to prevent galvanic corrosion per SAE/USCAR-2 specifications.

Technical Deep-Dive: 2026 Material Science & Signal Architecture

Mazda's 2026 MX-5 Miata ND3 continues the marque's Gram Strategy ethos, demanding sensors that deliver maximum signal fidelity with minimal mass. The Koeep 1800442 (Camshaft) & 1800441 (Crankshaft) sensor pair answers this requirement with a glass-fiber-reinforced PPS (Polyphenylene Sulfide) sensor body — the same high-performance thermoplastic specified in 2026 OEM sensor housings for its exceptional dimensional stability across -40°C to +180°C thermal cycles. The sensing element utilizes an InSb (Indium Antimonide) Hall-effect IC from the 2026 Infineon TLE496x series, delivering a 3.5 mV/Gauss sensitivity with sub-10 µs response latency. This enables the MX-5's PCM to execute per-cylinder ignition trim and VVT phasing with the granularity required for 2026 CARB LEV IV and Euro 7 evaporative and combustion emissions compliance. The crankshaft sensor's 58X trigger-wheel decoding supports misfire detection resolution down to 0.5%, exceeding the 2026 OBD-II mandated 1.0% threshold under ISO 27145-4 WWH-OBD monitoring requirements.

Critical to 2026 diagnostic architecture, these sensors transmit via the SAE J2716 SENT-B (Single Edge Nibble Transmission, Revision B) protocol, which doubles the data throughput of legacy SENT while maintaining backward pin compatibility. This ensures compatibility with both the 2026 MX-5's PCM and previous-generation Mazda ECUs found in the NB/NC Miata, 323, and Demio platforms — a deliberate design choice validated through Koeep's multi-vehicle qualification testing.

Technical Verification & OEM Cross-Reference

The following Technical Matrix consolidates the 2026 compliance framework, DTC mapping, and lifecycle data for the Koeep 1800442/1800441 Camshaft & Crankshaft Position Sensor Kit. All specifications are traceable to current 2026 SAE International, ISO, and Mazda OEM engineering standards.

1. Material Standard: The sensor body conforms to SAE J1639 (Classification for Automotive PPS Composites) with a UL 94 V-0 flammability rating. The InSb Hall IC is qualified to AEC-Q100 Grade 0 (-40°C to +150°C ambient, extended to +180°C junction), and connector terminals meet SAE/USCAR-2 Rev.7 performance class 3 (150°C, gold-plated). RoHS 3 (EU Directive 2025/2026) compliance is confirmed with full material disclosure; REACH SVHC screening shows zero substances above 0.1% w/w threshold.
2. DTC Mapping: This sensor kit directly resolves the following OBD-II DTC families as defined under ISO 27145-4 (WWH-OBD) and SAE J2012-DA (2026 Edition): P0335–P0339 (Crankshaft Position Sensor Circuit Range/Performance), P0340–P0349 (Camshaft Position Sensor "A" Circuit), P0365–P0369 (Camshaft Position Sensor "B" Circuit), P0011/P0012 (VVT Over-Advanced/Retarded — camshaft signal correlation), and P0315 (CKP System Variation Not Learned). Additionally, the sensors prevent erroneous triggering of P0300–P0304 (Random/Specific Misfire) and U0401 (Invalid Data from ECM) on the CAN-bus 3.0 network.
3. SKU/Lifecycle: Koeep SKU 1800442-1800441-KIT. Projected service life: 2026–2030, covering the full Mazda MX-5 ND3 production run and extending through the anticipated ND4 transition (2028–2030). The sensor pair is designed for a 100,000-mile / 10-year mean time between failures (MTBF) under normal operating conditions, validated through accelerated thermal cycling (1,000 cycles, -40°C/+180°C) and vibration testing per ISO 16750-3 (Test VII — random vibration, 10–2,000 Hz, 27.8 m/s² RMS). Each unit ships with a QR-coded batch traceability label enabling full forward/reverse lot tracking for ISO/TS 16949 quality system compliance.
