Product Information
Full details
The CRC Mass Air Flow Sensor Cleaner is an essential maintenance tool for car owners looking to restore engine performance and fuel efficiency without the need for expensive mechanic visits. It is specifically designed to safely dissolve contaminants from delicate MAF sensor wires, offering a quick path to improved throttle response and smoother idling. While it is highly effective at removing buildup, it is important to note that it should only be used on Mass Air Flow sensors, as it is a specialized solvent that may not be suitable for other sensitive electronic components.

FAQs
Can I use this on a throttle body?
No, this is specifically formulated for MAF sensors. Use a dedicated throttle body cleaner for that application.
How often should I clean my MAF sensor?
It is generally recommended to clean the sensor whenever you replace your engine air filter or if you notice performance issues.
Is it safe for hot-wire sensors?
Yes, this formula is specifically designed to be safe for hot-wire and hot-film style sensors.
Will this leave a film on the sensor?
No, the CRC formula is designed to leave zero residue after it evaporates.
Can I spray this while the engine is running?
No, you must always turn off the engine and disconnect the sensor before cleaning to prevent electrical damage.
Troubleshooting
Check engine light remains on after cleaning
The fault code may need to be cleared manually using an OBD-II scanner, or the sensor itself may be permanently damaged.
Engine performance does not improve
The sensor may have failed electronically rather than being dirty, or there may be a vacuum leak elsewhere in the intake system.
Pros and Cons
Pros
- Increases fuel efficiency by ensuring accurate sensor readings
- Easy to use with an aerosol delivery system
- Dries quickly with no residual buildup
- Safe for use on delicate plastic and metal components
Cons
- Not suitable for cleaning other non-MAF electronic components
- Requires careful handling to avoid physically damaging fragile sensor wires
- Only effective if the MAF sensor is dirty and not faulty
Setup, Compatibility & Care
To use this product, ensure your engine is turned off and the MAF sensor is completely disconnected from the vehicle's electrical system. Before spraying, ensure the area is free of large debris. Hold the can approximately 6-8 inches from the sensor and spray lightly, allowing the cleaner to soak into the buildup. Do not scrub the wires, as they are extremely fragile and easily broken. Allow the sensor to dry completely, which happens rapidly, before reinstalling it into the air intake boot. Always ensure the electrical connector is clicked firmly back into place before starting the vehicle.
