An automotive maintenance spray designed to clean sensitive air flow sensors and restore accurate airflow readings, Liqui Moly Air Flow Sensor Cleaner. Peace of mind for DIY mechanics and technicians who want a quick, residue-free result. Is the compact 200 ml spray a practical way to avoid unnecessary diagnostics and garage visits?
⚡ At a Glance
- • Cleaning Performance: Fast-acting solvent dissolves deposits on hot wire and hot plate, evaporates quickly and leaves no residue
- • Best for: Owners and mechanics performing maintenance on air flow sensors in petrol and diesel engines
- • Not ideal for: Sensors that cannot be removed or require manufacturer-specific service procedures
Special active solvent cleans sensitive components such as the hot wire and hot plate. Very fast evaporation prevents residue from affecting sensor readings.
Restores smooth idling - with residue-free active solvent
Special active solvent targets deposits on the hot wire and hot plate, breaking down contaminants before evaporating rapidly without leaving residues.
Smooth idling and more stable engine behaviour follow cleaning, because airflow readings return closer to factory values.
Precise, targeted cleaning - with a service spray for hot wire and hot plate
Service spray application allows controlled coverage of sensitive sensor components, and instructions recommend disconnecting the electrical connection and removing the sensor before use.
Targets the exact parts that cause incorrect measurements, making sensor servicing feasible as a careful DIY task.
Cost-saving preventive maintenance - thanks to quick contaminant removal
Removes deposits that can lead to misreadings and erratic idling, and is specified as suitable for both petrol and diesel engines.
Helps avoid unnecessary diagnostics and repairs by addressing common sensor faults early, extending sensor reliability when used correctly.
