Product Description
Car Oxygen Sensor 1588A195 For Mitsubishi
Lambda Sensor (Oxygen Sensor)
OE Part Number: 1588A195
Product Overview
The Lambda Sensor with OE number 1588A195 is an Original Equipment (OE) component manufactured for Mitsubishi vehicles. This 4-wire heated oxygen sensor monitors oxygen content in exhaust gases and relays this information to the Engine Control Unit (ECU), ensuring optimal air-fuel mixture for efficient combustion and reduced emissions.
This sensor is widely used across Mitsubishi models including Lancer, Outlander, ASX, RVR, and Galant Fortis, fitted with 4B10, 4B11, and 4B12 engine families. It is typically installed in the rear (downstream / post-catalyst) position, located after the catalytic converter.
As a direct-fit component, it features vehicle-specific electrical connectors and pre-terminated wiring, eliminating the need for cutting or splicing during installation. The threads are factory pre-greased with anti-seize compound for quick and easy replacement.

Compatible Vehicles
This Lambda Sensor is an original equipment component used across a wide range of Mitsubishi vehicles. Based on extensive cross-reference data, the sensor is typically installed in the rear (downstream / post-catalyst) position.
⚠️ Important Position Note: This is a rear (downstream / post-catalyst) oxygen sensor — installed after the catalytic converter. Do not use it in the upstream (pre-catalyst / front) position unless your vehicle's original sensor was located there. Upstream and downstream sensors are not interchangeable on most vehicles.
