CFMoto EFI Oxygen Sensor

OEM Part Number 018B-176000 (Old P/N: CF188-B-176000)

Widely used across CFMoto ATV, UTV, SSV, and Motorcycle models, covering 150cc to 1000cc.

📋 Overview & Working Principle

This oxygen sensor is a high-quality OEM replacement for CFMoto EFI (Electronic Fuel Injection) systems, part number 018B-176000 (old P/N CF188-B-176000). It is installed in the exhaust stream to measure the amount of oxygen in the exhaust gas and sends a real-time signal to the ECU (Engine Control Unit).

The ECU uses this feedback to precisely adjust the fuel injector output, ensuring the engine operates near the ideal air-fuel ratio (stoichiometric ratio of 14.7:1). This closed-loop control process achieves the following:

Reduces Emissions: Minimizes both unburnt hydrocarbons and nitrogen oxides released into the atmosphere.
Improves Fuel Economy: Prevents overly rich (wasteful) or overly lean (power-robbing) mixtures.
Optimizes Engine Performance: Ensures smooth operation and responsive power delivery under all conditions.

✨ OEM Quality: Manufactured with high-temperature resistant materials and precision sensing elements, providing fast response and accurate signals to ensure proper closed-loop engine control and emissions compliance.

📌 Compatibility Note: This oxygen sensor fits the extensive list of CFMoto models above, covering ATVs, UTVs, SSVs, and motorcycles from 150cc to 1000cc. Due to the wide range of applications, please verify your original oxygen sensor's part number (018B-176000) to ensure a correct match before ordering.

⚙️ Product Features

Direct OEM Replacement: Perfectly matches CFMoto part numbers 018B-176000 and CF188-B-176000, ensuring correct fitment and electrical specifications.
Precise Signal Output: Utilizes a high-quality zirconia sensing element for fast response and stable signals, providing accurate air-fuel ratio feedback to the ECU.
High-Temperature Resistance: Designed to withstand the high-temperature environment of the exhaust system for long-term reliable operation.
Closed-Loop Control Core: A critical component for the EFI system's closed-loop operation, optimizing emissions and fuel economy.
Diagnostic Reference: A faulty oxygen sensor often triggers the check engine light, increased fuel consumption, reduced power, and emissions test failure.

✅ Typical Symptoms of Oxygen Sensor Failure: An aging, contaminated, or failed oxygen sensor can cause: an illuminated Malfunction Indicator Lamp (MIL/Check Engine Light), rough idle, hesitation or stumbling during acceleration, noticeably higher fuel consumption, black smoke from the exhaust, and failing emissions tests. If you experience these issues, the oxygen sensor should be checked.

⚠️ Installation Tip: Ensure the threads in the exhaust pipe are clean before installation. Use a dedicated oxygen sensor socket and tighten to the specified torque to avoid damaging the sensor. Applying a small amount of anti-seize compound to the threads is recommended for future removal. Clear any ECU fault codes after installation.
