Walker Products Mass Air Flow Sensor P/N:245-1451
Walker Products 245-1585 mass air flow sensor for the 2016-2019 Volkswagen Transporter 4-cylinder 2.0L and other vehicles measures the air entering the engine so the ECU can fine-tune the air-fuel mix.
A rough idle, hesitation or a check engine light can mean the mass air flow sensor is worn, though a cracked intake duct or a failing oxygen sensor can produce similar symptoms.
The 2016-2019 Volkswagen Transporter 4-cylinder 2.0L, the 2018-2023 Volkswagen Atlas V6 3.6L and the 2020 Atlas 4-cylinder 2.0L, and the 2021-2023 Volkswagen Teramont V6 3.6L all take this sensor, along with other vehicles. This listing is one sensor assembly; the 2018-2023 Volkswagen Atlas V6 3.6L takes one. Open the "Vehicles it fits" section to check your exact model and engine.
