Do not buy the cheap no name remanufactured or rebuilt Chevrolet Avalanche electronic control units, as in our experience most of these ecu’s don’t even work right out of the box. We also carry programmable Chevrolet Avalanche control units from AEM that allows you to custom program your Chevrolet Avalanche ignition and fuel system.
Replace your faulty Chevrolet Avalanche Mass Air Flow Sensor with a Genuine or OE Bosch Unit to keep your Chevrolet running like new.
The Chevrolet Avalanche Oxygen sensor is a critical part of the emmision control system and should be replaced as soon as it fails. Make sure to check the Chevrolet Avalanche diagnosics codes for proper replacement of the O2 Sensor.
