The MAF sensor on a 2020 Chevy Malibu sits in the engine’s air intake tract, typically in the plastic intake tube between the air filter housing and the throttle body. This placement is standard for the Malibu’s common 1.5L turbo engine and the available 2.0L turbo option.
In practice, the sensor is a small rectangular device mounted in the intake pipe, upstream of the throttle body, where it measures incoming air mass and feeds data to the engine computer to regulate fuel delivery.
Where to look in the engine bay
To locate it on a 2020 Malibu, follow the air path from the air box to the engine. The MAF is housed in the intake pipe and is accessible from the top or side of the engine bay, depending on trim.
Note that layout can vary slightly by trim and engine, but the standard arrangement keeps the MAF in the air duct rather than inside the throttle body itself.
Access and safety considerations
- Open the hood and identify the air filter housing (usually on the passenger side near the fender).
- Trace the intake tube from the air box toward the engine; look for a small rectangular sensor bolted or clipped to the pipe.
- Follow the wiring harness from the sensor to the engine control module to confirm you’ve found the MAF.
Access is typically straightforward; ensure the engine is cool before touching components. If in doubt, consult the vehicle’s service manual or a technician.
Why the MAF location matters
Knowing the location helps with diagnostics and maintenance. A dirty or damaged MAF can cause erratic idle, poor fuel economy, or stalling, so understanding where it sits makes inspection and cleaning or replacement easier.
Summary
For a 2020 Chevy Malibu, expect the MAF sensor to be in the air intake duct between the air filter box and the throttle body, a layout that applies across the common 1.5L turbo and the optional 2.0L turbo engines. Access is usually simple from the engine bay, and proper care should be taken when inspecting or replacing the sensor.
