Liqui Moly Air Flow Sensor Cleaner is a specialized solution designed for the fast and gentle cleaning of sensitive components within air flow sensors. This cleaner features a unique formula that evaporates quickly and leaves no residue, making it ideal for maintaining the optimal performance of your vehicle's engine. Dirty air flow sensors can lead to shifting problems in vehicles with automatic transmissions and can affect the fuel/air mixture calculations, potentially causing engine issues. By using this cleaner, you can often avoid the costly replacement of the sensor. Its active solvent effectively removes contaminants from the hot wire or hot plate of air flow sensors, ensuring accurate readings. It is suitable for use in both gasoline and diesel engines.Application Instructions:Disconnect the electrical connection of the air flow sensor and remove the sensor. Spray the dirty components, such as the hot wire or hot plate, generously with the cleaner and allow the dirt to drip off. Avoid touching the sensitive components of the sensor. Ensure the solvent dries completely before reinstalling the sensor. It is recommended to apply this cleaner every time the air filter is replaced or when performance issues arise.Important Note: Before applying to plastics that are sensitive to solvents, especially on mechanically stressed parts, conduct a compatibility test.
