Downstream O2 Lambda Sensor Nissan Micra Juke 1.2 HR12DE 226A0-1HC0A AKAS

The AKAS Downstream O2 Lambda Sensor is a precision 4-wire heated post-catalytic converter (rear) replacement for Nissan Micra (K13) and Juke (F15) equipped with HR12DE 1.2L 3-cylinder petrol engines, replacing OE 226A0-1HC0A (cross-ref 226A0-3NT0A).

PETROL ONLY - not compatible with diesel engines. This downstream (post-cat / Bank 1 Sensor 2 / Rear) oxygen sensor monitors catalytic converter efficiency by comparing exhaust oxygen levels after the catalyst - critical for emissions compliance, fuel efficiency, and clearing P0420 catalyst efficiency check engine lights. Premium high-temperature construction with anti-carbon and anti-corrosion coating ensures long service life. Plug-and-play 4-pin OE connector. Backed by a 6-month limited warranty.

1. 4-Wire Heated Downstream O2 - Catalyst Efficiency Monitor This is a 4-wire heated oxygen sensor for the DOWNSTREAM (post-cat / Bank 1 Sensor 2 / Rear) position, monitoring catalytic converter efficiency by comparing exhaust oxygen levels after the catalyst. Essential for emissions compliance, fuel efficiency, and clearing P0420/P0430 catalyst efficiency check engine lights. Replaces OE 226A0-1HC0A (cross-ref 226A0-3NT0A).

2. Exact OE Match - Nissan Micra/Juke 1.2 HR12DE Only Precision downstream direct-fit sensor for Nissan Micra (K13) 2011-2017 and Juke (F15) 1.2 2014-2017 with HR12DE 1.2L 3-cylinder petrol engines. 1:1 OE dimensions, 4-pin OE connector, M18x1.5 thread - no modification, splicing, or adapter needed. PETROL ONLY - not compatible with 1.5L (HR15DE), 1.6L (HR16DE), or diesel engines. NOT for upstream (pre-cat) position.

3. Fast Light-Off & Precision - Restores Emissions & Clears CEL Integrated heating element brings the sensing element to operating temperature in under a minute, ensuring accurate oxygen concentration readings even during cold starts and short urban trips. Fast-response signal module transmits reliable oxygen data to the ECU, restoring proper catalytic converter efficiency monitoring, improving fuel economy, reducing emissions, and clearing check engine lights (P0420/P0136/P0141 series) caused by a faulty or ageing downstream sensor.

4. Premium High-Temp Construction - Anti-Carbon, Long Lifespan Premium high-temperature alloy probe with oxidation-resistant outer shell delivers reliable performance under harsh exhaust conditions. Anti-carbon-build-up and anti-corrosion surface treatment resists erosion from hot exhaust fumes, carbon deposits, and oil/PCV impurities - significantly prolonging service life vs. uncoated cheap sensors that fail prematurely from carbon fouling. Waterproof/dust-proof integrated sealing and anti-vibration internal circuit ensure consistent performance.

5. OE Quality at Aftermarket Value - 6-Month Warranty Manufactured to strict OE specifications with dependable detection accuracy, rapid signal feedback, solid high-heat tolerance, and anti-vibration capability - performing comparably to the NTK/Denso OE sensor at a fraction of Nissan main dealer cost. Backed by a 6-month limited warranty covering manufacturing defects. For South African Nissan Micra/Juke owners - where Nissan Micra is a popular compact hatchback and Juke is a distinctive crossover, and downstream sensor failure is a common cause of P0420 catalyst efficiency codes, failed emissions/roadworthy tests, and reduced fuel economy.

1.2L PETROL ONLY - VERIFY COMPATIBILITY: This downstream sensor fits ONLY Nissan Micra (K13) and Juke (F15) with HR12DE 1.2L 3-cylinder petrol engines, replacing OE 226A0-1HC0A (cross-ref 226A0-3NT0A) in the DOWNSTREAM (post-cat / Bank 1 Sensor 2 / Rear) position. NOT compatible with 1.5L/1.6L, NOT with diesel, NOT for upstream (pre-cat) position, NOT for other OE numbers. Check original OE number, engine code, and sensor position before purchase.

DOWNSTREAM ONLY - DO NOT SUBSTITUTE FOR UPSTREAM: This is a DOWNSTREAM (post-cat / Bank 1 Sensor 2 / Rear) oxygen sensor. Do NOT install in the upstream (pre-cat / Bank 1 Sensor 1) position - upstream and downstream sensors have different calibrations and are NOT interchangeable. Upstream OE is 22690-1HC0A (different part number).

4-WIRE HEATED - VERIFY CONNECTOR PIN COUNT: This is a 4-wire heated oxygen sensor. Ensure the connector has 4 pins before installation. Do NOT substitute with a 1-3 wire unheated sensor or a 5-wire wideband AFR sensor - they are electrically and functionally different and will cause incorrect readings and persistent check engine lights.

PROFESSIONAL INSTALLATION: Recommended for proper torque (30-45 Nm), correct cable routing away from heat sources and moving parts, and clearing of diagnostic trouble codes (DTCs) after replacement. Allow exhaust to cool completely (30-60 min) before servicing. Do not over-tighten. If the mounting bung thread is damaged or carbon-fouled, clean/repair before installation.

WARRANTY: 6-month limited warranty covering manufacturing defects under normal use. Does not cover improper installation, drops, contamination, water ingress, use on incompatible vehicles/engines, wrong position (upstream), modification, or normal wear. This is an aftermarket replacement part - not affiliated with or manufactured by Nissan, NTK, or Denso.
