How to Replace a Mass Air Flow Sensor on an 85 Corvette

Iskandar Blogger 8:04 PM

In 1985, Chevrolet installed a mass air flow sensor on a Corvette for the first time, replacing the air density system that merely predicted engine air consumption instead of accurately recording it. The MAF sensor reads specific air volume and provides that information to the on-board computer. The computer then uses that information to properly balance the fuel input to achieve the optimal air-to-fuel ratio based on throttle position and response. The MAF sensor resides in the air intake tube, between the air cleaner assembly and the throttle body.

Instructions

    1

    Turn off the engine and open the Corvette's hood. Unplug the engine wiring connector from the base of the MAF sensor.

    2

    Release the forward clamps on the MAF to unhook it from the air cleaner assembly outlet tube. Loosen the hose clamp on the engine side of the MAF sensor, using a screwdriver.

    3

    Pull the old MAF sensor off the engine side tube and set it aside. Slide the new MAF onto the engine side tube. Tighten the hose clamp, using the screwdriver, after ensuring the tube mates securely all the way around the MAF sensor.

    4

    Place the air cleaner assembly outlet tube onto the inlet of the new MAF sensor. Slip the edges of the forward clamps onto the air cleaner assembly outlet tube and lock them down.

    5

    Plug the engine wiring harness connector into the new MAF sensor. Close the Corvette's hood.
