1986 Mass Air Flow (MAF) Sensor Power Electric Relay

When replacing your 1986 Corvette Mass Air Flow (MAF) Sensor, replacement of both the Power Relay and Burnoff Relay is highly recommended. Without replacing these relays, you risk possible damage to your new Mass Air Flow Sensor, as well as continued engine trouble codes.

  • For 1986 Corvettes
  • Power Relay Only

MAF Sensors measure the air coming into the engine in grams per second. At idle, there should be 8 grams per second. The Burnoff Relay has two large orange wires at connecting point. The relay with one wire is the Power Relay
