## Overview

LIQUI MOLY Air Flow Sensor Cleaner is a 200ml fast-evaporating spray designed to gently and effectively clean sensitive air flow sensors in gasoline and diesel engines. By removing contaminants from the hot wire or hot plate, it restores accurate fuel/air mixture readings, improving engine performance, fuel efficiency, and transmission shifting. Easy to use and residue-free, this cleaner helps avoid expensive sensor replacements and costly garage visits, making it an essential maintenance tool for savvy vehicle owners.

## Description

Product Description Special active solvent for fast and gentle cleaning of sensitive components of the air flow sensor in gasoline and diesel engines. The Cleaner also distinguishes itself by means of a very fast evaporation that is free of residues. A dirty hot wire or hot plate in the air flow sensor leads to incorrect readings for calculating the fuel/air mixture. The starting and idling properties of the vehicle are thus impaired, the engine performance is reduced and the fuel consumption increases. Also, dirty sensors on vehicles with automatic transmissions can cause shifting problems. Thanks to the use of the Air Flow Sensor Cleaner, an expensive replacement of the sensor can most likely be avoided. Ingredients LIQUI MOLY Air mass sensor cleaner, 200 ml, service spray, item number: 4066, colourless

Review: Simple solution that saved me a potentially expensive garage visit - Here's a detailed review for the LIQUI MOLY Air Flow Sensor Cleaner: Simple solution that saved me a potentially expensive garage visit ⭐⭐⭐⭐⭐ My car had been experiencing rough idling and occasional stalling, symptoms that typically point to expensive engine diagnostics and repairs. Before heading to the garage for what I expected to be a costly investigation, I decided to try cleaning the mass air flow sensor myself with this LIQUI MOLY cleaner - and I'm glad I did. Effectiveness and results: The transformation was immediate and impressive. After spraying the sensor according to the instructions and letting it dry, the rough idling completely disappeared and the engine returned to smooth operation. What I thought might be a major engine issue turned out to be simply a dirty MAF sensor that this cleaner handled perfectly. The car now runs as smoothly as it did when newer. Ease of use: The process couldn't be simpler - locate the sensor, spray, wait for it to dry, and reassemble. The 200ml can provides plenty of product with a precise spray pattern that makes it easy to target the sensor elements without oversaturating. Clear instructions on the can help even novice DIYers feel confident about the process. Value proposition: At under £10, this saved me what could easily have been a £100+ diagnostic fee plus labor costs at a garage. Even if you only use it once, the savings are substantial. The can contains enough product for multiple applications, making it excellent value for money. Quality and reliability: LIQUI MOLY has a solid reputation for automotive chemicals, and this product lives up to that standard. The cleaner evaporates cleanly without leaving residue, and I've had no issues with sensor damage or performance problems after use. Practical considerations: The spray can is compact and stores easily in a garage or toolbox. The product has a reasonable shelf life, so you can keep it on hand for future maintenance. Bottom line: This is one of those products that can save significant money and hassle. If you're experiencing engine performance issues that might be MAF sensor related, this is definitely worth trying before expensive garage diagnostics. It's become a permanent addition to my basic car maintenance toolkit.
Review: Great. Strong smelling. Powerful. Just like how I like my women - Used this Liqui Moly airflow sensor cleaner and honestly it felt like I just gave my engine a lung transplant. A few sprays and the sensor went from “wheezing pensioner” to “Olympic sprinter” in about 30 seconds. The idle smoothed out, throttle response sharpened up, and my MPG actually crept up like it was trying not to get noticed. Engine feels cleaner, happier, and way less moody on cold starts. Super easy to use too — remove sensor, spray, let it dry, pop it back in. No oily residue, no weird smells, no accidental engine explosions. Just clean, crisp airflow like the car can finally breathe properly again. If your engine feels a bit sluggish or grumpy, this stuff is basically a spa day for your airflow sensor.

## Questions & Answers

**Q: Hello can i use this item to clean my MAP & IAT sensor thank you**
A: I cannot give a definite answer. I don't think it will clean the actual electronic part of the sensor as those parts would be too delicate, and may damage the sensor. But it will clean any build up of dirt around the sensor body etc… There are lots of YouTube Videos on how to clean MAP & IAT sensors – would be worth watching them first!

**Q: Can you spray this directly down the Throttle body intake, my vehicle the air in take sensor is non removeable.**
A: Hello Nesty
Yes, procedure to follow and remember I am not an expert in this would be to locate the car in a well ventilated place, outside, switch off the engine, remove the Air Filter, look into the Inlet and locate the Sensor, Stainless Steel Strip suspended in the Air Flow, and direct a good 5 second spray at it, wait about 10 minutes and give a second spraying, the liquid evaporates instantly, spray again after about 10 minutes, refit the Air Filter. Wear mask and eye and glove protection, do not breathe in the Liqui Moly.

**Q: Can I use this to clean engine idle valve?**
A: Hi Chris, I would say that from experience, there are some brands of cars that are made with an Idle Valve or a Throttle Body that are easy to keep clean and maintain without the pain of replacement. It is all down to getting to know your engine first and foremost. Cleaning an idle air control valve can keep you from buying a new part, but only certain idle air-control valves can be cleaned. The idle air-control valve must have a spring-operated valve for cleaning to make it work and often with spring-loaded valves you can buy products on the market that are specifically designed to clean unwanted build-up of grease etc. I would, however, warn you away from using this Air Flow Sensor product on anything other than what it is designed to work on. There are a number of Throttle Body and valve cleaners on the market, but hey are often just delaying the inevitable. If your car has a rough idle, it could be a number of things and a thorough inspection from a trusted mechanic would be my first suggestion. I had the same issue with a recently purchased 2003 Land Rover V8, the rough idle was all to do with a combination of poor fuel injectors, a clogged air flow and throttle body; sticks of coal where once stood spark plugs and a faulty HT lead on two cylinders. I would suggest speaking to a mechanic first and if it is a clogged idle valve and nothing else, it's a few £ to give it a good clean. However, if it is something else and you can't find it, you could be doing more damage to the engine. Good luck and wishing you a speedy and inexpensive diagnosis.

**Q: Hi can i use this to clean my diesel particle filter additive on a Peugeot 3008?**
A: Hi there,
My answer to your question is: rather no. Liqui Moli Air Flow Sensor Cleaner is a liquid for very sensible electrically connected parts.
I believe, for the task, you undertake something chipper will do the job. But no one can stop you to try.
