Your cart is empty.Mass airflow sensors measure the amount of air by weight through changing voltages or frequencies and sends this information to the onboard computer. The computer uses this and other inputs to calculate the correct amount of fuel delivered. Symptoms of failure include poor starting, engine surging, engine stalling, a check engine light, and no-start conditions. Sensors are non-serviceable, replace sensors that are non-functional.

An authentic Garbage! Wanted a quality Mass Airflow sensor for my Chevy Suburban 1999 and I’ve got a no name and damaged product. It came with electronic case broken and without one of the resistances, tested it anyway and it doesn’t work. It’s a real shame for Walker Products

Maintenance light was coming on for short period climbing hills or at startup. Replaced oxy sensors but light still came on. Code reader finally indicated a bad mass air flow sensor. Bought this one at a good price for a non-plastic sensor. Much better power at cold start and maintenance light stopped coming on.

So, this has been on my car for a few months now. I bought it because I had a mass air flow SES code, and this seemed like an easy fix. Sadly, the actual fix was even easier (turned out to be a blown fuse that also controls the reverse lockout solenoid), but with over 450,000 miles on the original MAF, I figured it wasn't a bad idea to have changed it anyway. :)This is a direct fit replacement, and took only about five minutes to swap in. It probably took me more time to dig out tools (a screwdriver) than to do the actual replacement.
