Standard Ignition AS327 manifold absolute pressure sensor for the 2019 Subaru Outback H6 3.6L and other vehicles sends instantaneous manifold pressure data to the powertrain's electronic control unit. Often called a MAP sensor, it is lab tested to match OE specifications for proper integration with the vehicle's emissions system.
A failing manifold absolute pressure sensor can show up as a rough idle, weaker fuel economy or a check engine light. A leaking vacuum hose, a damaged connector or a dirty throttle body can sit behind those signs as well, so track down the cause before you buy. This listing is one sensor, and the engine takes just one.
It is listed for a wide range of Subaru models, including the 2019 Subaru Legacy H6 3.6L and the 2005 Subaru Forester H4 2.5L. Open the "Vehicles it fits" section and look up your exact model year and engine.
Fit and size
Build and materials
One manifold absolute pressure sensor with O-rings. The wiring harness, hardware and mounting bracket are not included, so plan on new mounting hardware because the old pieces may not be reusable.
Does the Standard Ignition AS327 fit the 2019 Subaru Legacy H6 3.6L?
Yes. Standard Ignition AS327 is listed for the 2019 Subaru Legacy H6 3.6L, and that engine takes one sensor.
Does the AS327 manifold absolute pressure sensor come with O-rings and a wiring harness?
Standard Ignition AS327 includes O-rings. The wiring harness, hardware and mounting bracket are not included.
How many terminals does this manifold absolute pressure sensor have?
The rectangular plug-in connector is female and holds four male blade terminals. The sensor also has one vacuum port.
Can a check engine light and rough idle come from a bad manifold absolute pressure sensor?
Yes, they can, and so can weaker fuel economy. A shop can scan the stored codes and test the sensor.
Is the AS327 built to handle temperature swings?
Yes. Its high-grade materials are made to protect against extreme temperature changes and exposure to damaging elements.
