Sensor de oxígeno O2 antes y después del catalizador para Nissan NV200 (2013-2021) 2.0L

Direct-Fit Upstream & Downstream O2 Sensor Kit for 2013-2021 Nissan NV200 (M20)

What it Does: This matched upstream and downstream O2 sensor kit for the 2013-2021 Nissan NV200 (M20) MR20DE 2.0L monitors exhaust air-fuel ratios and catalyst efficiency.

The Stock Nissan NV200 Sensor Failure

On high-mileage M20 vans with the MR20DE 2.0L engine, factory oxygen sensors suffer thermal fatigue, carbon fouling, and heater element burnout. Continuous exhaust heat soak degrades the zirconia ceramic and fractures internal platinum electrodes. As response latency increases, the ECM loses closed-loop fuel trim control, triggering P0130, P0135, or P0138 codes alongside false P0420 catalyst alerts.

Common Symptoms of a Failing OEM O2 Sensor

• Check Engine Light: Codes like P0130, P0135, P0138, or P0420 from heater failure or slow switching.
• Rich Fuel Mixtures: Delayed feedback causes erratic injector trims, exhaust soot, and poor fuel economy.
• Emissions Failure: Rough idling and incomplete OBD-II readiness monitors.

The Direct-Fit Dual-Sensor Solution

This matched set replaces Bank 1 Sensor 1 (234-9135 / 226931MR0A) and Bank 1 Sensor 2 (234-4599 / 226933RC0A) together for balanced closed-loop feedback. Each unit features laser-welded stainless housings, high-temp zirconia elements, and calibrated internal heaters for fast light-off. Direct-fit connectors and OE-length harnesses plug straight into the M20 wiring without splicing.

What's Included

Frequently Asked Questions & Fitment Warnings

Does this fit the M20 NV200?

Yes. Fits 2013-2021 Nissan NV200 models with the MR20DE 2.0L engine. Confirm your 2.0L engine before ordering; other engines or badges are excluded.

Will this clear P0135 or P0420 codes?

Yes, when caused by worn sensors. Replacing 234-9135 and 234-4599 fixes heater and response faults; inspect the catalytic converter if P0420 remains.

Is wiring modification required?

No. Both sensors use direct-fit connectors for plug-and-play installation; keep anti-seize off the sensing tip.
