Oxygen Sensor

Fits Linhai 300-750cc EFI Models

Part Number: 70826 / 4AB-14640-00

📋 Overview

It's located in the exhaust stream to measure the amount of oxygen in exhaust and send the signal to ECU, which can revise the fuel injector output, so as to reduce the amounts of both unburnt fuel and oxides of nitrogen entering the atmosphere. This optimizes the air-fuel ratio, improves fuel economy, and reduces emissions.

✨ OEM Quality: Manufactured to exact original specifications using quality sensor components, ensuring accurate oxygen measurement and reliable performance.

Sends signals to ECU for air-fuel ratio optimization
Improves fuel economy
Reduces harmful emissions
Direct replacement for faulty original sensor

⚙️ Operating Principle

The oxygen sensor is mounted in the exhaust pipe, monitoring oxygen content in the exhaust gas. High oxygen indicates a lean mixture; low oxygen indicates a rich mixture. The sensor sends voltage signals to the ECU, which adjusts fuel injection to maintain the ideal air-fuel ratio (around 14.7:1), achieving optimal combustion efficiency, minimal emissions, and best fuel economy.

📌 Failure Indication:

If the check engine light comes on, fuel consumption increases, power drops, or emissions exceed limits, the oxygen sensor may be faulty. Inspect and replace as needed to maintain optimal engine performance and emissions levels.

✅ OEM specification replacement: This oxygen sensor (70826/4AB-14640-00) fits Linhai 300-750cc EFI models. Ensures precise air-fuel ratio control by the engine management system, optimizing performance and emissions.
