Give the powertrain control module the intake-pressure data it depends on with the Standard Ignition Manifold Absolute Pressure Sensor AS637. It installs as a direct-fit replacement across a wide range of Ford and Lincoln applications, from the 2015-2024 Ford Edge and 2015-2025 Ford F-150 to the 2020-2024 Lincoln Aviator and 2018-2024 Lincoln Navigator.

  • Measures manifold absolute pressure: reads the pressure inside the intake manifold so the PCM can calculate engine load.
  • Feeds fuel and timing control: the signal helps the PCM adjust fuel delivery and ignition timing for normal engine operation.
  • Direct-fit replacement: designed to install in place of the original sensor on the listed applications.

The manifold absolute pressure sensor monitors intake manifold pressure and reports it to the engine control system. Signs this sensor may need replacing include a rough idle, hesitation, poor fuel economy, or an illuminated check engine light. Because these symptoms can have other causes, diagnose the fault before replacing, and if a failed MAP sensor is the cause, this unit replaces it.

Fitment: 2015-2024 Ford Edge; 2015-2025 Ford F-150; 2015-2024 Ford Transit-150; 2015-2024 Ford Transit-250; 2015-2024 Ford Transit-350; 2015-2024 Ford Transit-350 HD; 2016-2018 Lincoln MKX; 2017-2019 Ford Fusion; 2017-2020 Lincoln Continental; 2017-2020 Lincoln MKZ; 2018-2024 Ford Expedition; 2018-2024 Lincoln Navigator; 2019-2024 Lincoln Nautilus; 2020-2022 Ford Escape; 2020-2024 Ford Explorer; 2020-2024 Ford Police Interceptor Utility; 2020-2024 Lincoln Aviator; 2021-2024 Ford Bronco Sport; 2024 Ford Ranger. See the Buyer's Guide tab for the full list.

Frequently Asked Questions

What does the AS637 do?

It's a manifold absolute pressure (MAP) sensor that reads intake manifold pressure and reports it to the PCM, which uses that data to help calculate engine load and adjust fuel delivery and ignition timing.

Will this fit my vehicle?

It's a direct-fit replacement for many 2015-2025 Ford and Lincoln models, including the F-150, Edge, Explorer, Transit-150/-250/-350, Expedition, Navigator and Aviator. Check the Buyer's Guide tab for the full list.

What are the signs the MAP sensor may need replacing?

Common signs include rough idle, hesitation, or poor fuel economy, often with a check engine light. These can have other causes, so diagnose the fault first; if the MAP sensor is to blame, this unit replaces it.

What part numbers does this sensor replace?

It interchanges with EC2021, MAPA162, 2-27256, CX2486, CX2494, CX2519, CX2569, DV2Z9F479B, DV2Z9F479C, DV2Z9F479D, GV2Z9F479B, GV2Z9F479D and PV4Z9F479A.

Is anything special needed to install it?

Installation replaces the original MAP sensor in its factory location. Consult the vehicle service information for the correct procedure and torque, and clear any stored trouble codes after the swap.
