LIQUI MOLY Luftmassensensor-reiniger | Air Flow Sensor Cleaner - 200ml

LIQUI MOLY Air Flow Sensor Cleaner 200ml (Art.No: 4066 / Luftmassensensor-reiniger) is a professional-grade, high-purity active technical chemical solvent developed and manufactured in Germany by LIQUI MOLY. Engineered precisely with a specialized combination of active solvents, this formulation is designated for the rapid and exceptionally gentle cleaning of sensitive components within Mass Air Flow (MAF) sensors across both gasoline and diesel engines. It targets and dissolves insulating oil films, grease mists, and environmental dirt crusts that settle onto the sensor’s delicate hot-wire probes over time, directly eliminating incorrect intake volume data sent to the engine control unit (ECU). Boasting ultra-fast chemical flash-off parameters, it dries completely residue-free, promoting precise engine calibration, smooth air-fuel management, and overall operational longevity safely.

Product Specifications:

• Brand: LIQUI MOLY.

• Product Type: Active, Fast-Evaporating, Residue-Free MAF Sensor Cleaning Solvent.

• Volume: (200ml).

• Country of Origin:  Germany .

Key Features & Operational Metrics:

• Ultra-Gentle & Rapid Decomposition: Formulated to effectively lift contaminants from delicate platinum hot-wires and thermistor beads without inducing mechanical stress or material degradation.

• Guaranteed Zero-Residue Evaporation: Flashes off entirely within seconds upon surface impact, leaving no film or tacky coatings behind to ensure the sensor does not attract future airborne soot.

• Corrects Air Mass Metrics: Completely uncovers the sensor's micro-fine components, enabling accurate air volumetric data transmission to the engine control unit (ECU).

• Optimizes Complex Air/Fuel Trims: Facilitates clean, stoichiometrically ideal combustion cycles based on true data, directly lowering harmful exhaust emissions.

• Restores Volumetric Powertrain Efficiency: Permanently eradicates rough engine idling, throttle hesitation, and performance dropouts stemming from insulated sensor probes.

• Augments Fuel Economy: Mitigates excessive and erratic fuel consumption patterns by re-establishing precise fuel injection calculations.

Application Protocol & Technical Directions:

• Ensure the vehicle's ignition is fully de-energized, disconnect the battery source, let components cool down, and unclip the MAF electronic wiring loom connector before servicing.

• Extract the plastic MAF sensor housing from the induction tract (situated between the air filter box and the throttle body).

• Shake the LIQUI MOLY No. 4066 canister thoroughly to mix the active compound under full line pressure.

• Aim the extended application tube directly at the internal sensing components from a distance of 10 to 15 cm, applying steady, sweeping bursts to flush away layered dirt and oil films.

• CRITICAL TECHNICAL CAUTION: Never permit physical contact between any tools, rags, cotton swabs, or fingers and the internal sensor wires. These micro-elements are fragile and will snap under mechanical load.

• Allow the sensor assembly to air-dry completely for a few moments through its rapid-evaporation action, then carefully bolt back into the intake tract and plug the harness back in securely.

Comprehensive System Adaptability:

• Certified as 100% neutral and highly recommended for servicing all modern configurations of hot-wire, hot-film, or cold-wire MAF sensor modules deployed across naturally aspirated or turbocharged gasoline and diesel passenger cars and light commercial commercial vehicles.

Note:

This technical fluid is highly pressurized and extremely flammable; never spray onto energized wiring or apply when local components are hot. Keep clear of active open workshop flames or mechanical sparks. Do not store in conditions exceeding 50°C. Avoid skin contact and inhalation of vapours.
