Oxygen Sensor Upstream Front Heated 5-Wire Lambda/02 For Mitsubishi Outlander 1588A228

Upgrade your Mitsubishi’s exhaust management with this upstream front oxygen sensor—Lambda/02 sensor 1588A228. This 5‑wire heated O2 sensor delivers precise oxygen feedback to the engine control unit, helping your vehicle achieve clean combustion, smoother idle, and better fuel efficiency across cold starts and varying driving conditions. Designed as a direct replacement for select Mitsubishi models, it ensures reliable performance without the guesswork of aftermarket parts.

Benefits & Tips

• Improved fuel economy and reduced emissions by delivering accurate air‑fuel ratio data to the ECU, helping the engine run optimally.
• Consistent cold‑start performance thanks to the built‑in heating element, so you won’t be left with rough starts or hesitation in chilly weather.
• Best results when used as a proper upstream replacement on compatible models; after installation, perform a short drive cycle to allow the ECU to re‑learn the new sensor data.
