Product Information

Full details

Liqui Moly Air Sensor Clean is an essential maintenance tool for automotive enthusiasts and DIY mechanics who want to optimize engine performance and prevent costly repairs. This specialized solvent is designed to safely remove contaminants from sensitive mass air flow (MAF) sensors in both gasoline and diesel engines, restoring accurate airflow readings and smooth shifting. While highly effective at restoring sensor functionality, it is a chemical solvent that requires careful handling and complete drying to prevent damage or combustion risks during engine restart.

Extended Product Information

FAQs

Can I use this on any air sensor?

This product is specifically designed for air flow sensors (MAF). Do not use it on other types of sensors unless specified by the manufacturer.

Do I need to scrub the sensor with a brush?

No, never touch or scrub the sensitive hot wire or plate. The spray pressure and solvent properties are designed to clean without physical contact.

How often should I clean the MAF sensor?

It is recommended to clean the sensor every time you replace your air filter or whenever you notice a decline in engine performance.

Is it safe for plastic components?

The formula is designed to be gentle on sensor components, which are typically made of high-grade plastics and metals; however, avoid spraying unnecessarily on unrelated engine bay plastics.

What happens if I reinstall the sensor while it is still wet?

You risk damaging the sensor or potentially causing a combustion issue. Always wait for the solvent to fully evaporate.

Troubleshooting

Engine performance does not improve after cleaning.

The sensor may have internal electrical failure rather than just surface contamination. Inspect the wiring harness for damage or consider a diagnostic scan.

Check Engine Light remains on.

After cleaning, you may need to clear the existing fault codes using an OBD-II scanner so the computer can recalibrate with the clean sensor data.

Sensor appears to have residue or spots after drying.

Ensure you are using the product in a clean environment and that no debris from the surrounding intake housing is falling back onto the sensor.

Pros and Cons

Pros

  • Prevents expensive sensor replacement costs
  • Dries rapidly without leaving harmful residue
  • Improves fuel efficiency and engine responsiveness
  • Safe for both gasoline and diesel MAF sensors
  • Simple, straightforward application process

Cons

  • Requires careful physical handling of fragile sensor components
  • Cannot fix sensors with internal electrical failure
  • Solvent must be allowed to evaporate fully before reinstalling
  • Not suitable for cleaning other heavy-duty engine parts

Setup, Compatibility & Care

To use the cleaner effectively, follow these safety and application steps:

  1. Preparation: Ensure the engine is completely off and cool. Locate the air flow sensor and disconnect the electrical harness.
  2. Removal: Carefully unscrew or unclip the sensor from the intake housing. Handle the unit with extreme caution to avoid damaging the delicate wire.
  3. Application: Spray the cleaner generously onto the sensing components (the hot wire or plate). Allow the dirt and contaminants to drip off naturally; do not touch, scrub, or wipe the sensor with tools or cloths, as this can break the delicate elements.
  4. Drying: Wait until the solvent has evaporated completely. Reinstalling a wet sensor can lead to a fire hazard or incorrect readings.
  5. Storage: Keep the canister in a cool, dry place away from open flames or extreme heat sources.
