Keep It Clean

Penray Inc. has introduced its new cleaner for mass air flow (MAF) sensors, part number 2520. While there are other MAF sensor cleaners on the market, this new formula is designed to be plastic-friendly.

It is well known that the delicate fine wire that senses the flow of air entering the induction system is subject to contamination. Dust, oily vapors and other contaminants can collect on this very fine wire, forming a layer of insulation that can cause it to provide inaccurate information to the car’s engine management computer.

The attachment point for the mass air flow sensor is usually a small plastic clip. Often aggressive solvents, like typical carburetor cleaners, can damage delicate plastic pieces. Penray 2520 is specially formulated to effectively clean the sensitive component without harming plastics, coatings or adhesives.

Use of Penray’s MAF sensor cleaner is easy. The sensor element is typically accessed by unsnapping a few retaining clamps and lifting off a piece of plastic ductwork to reveal the fine sensor wire. This wire is very fragile; physically touching it is not possible without likely damage. Once the sensor is removed from the duct, several sprays of Penray 2520 will quickly dissolve deposits, so the full length of the wire is once again free of contamination. Newly exposed to the rush of incoming air, the sensor is able to perform its job properly and accurately.
