Standard Ignition AS457 Manifold Absolute Pressure Sensor

Manifold Absolute Pressure Sensor for Mitsubishi Applications

Standard Ignition AS457 is a manifold absolute pressure sensor built for direct replacement on select Mitsubishi vehicles. It uses a 3-terminal, plug-in electrical connection with a rectangular female connector, black finish, and included O-ring for a secure seal at the intake manifold.

Key Features

• Manifold Absolute Pressure Sensor for intake manifold pressure monitoring
• 3 terminals with male blade terminals and 1 rectangular female connector
• Plug-in connector type for straightforward electrical connection
• 1 vacuum port and 1 port configuration
• Black housing with O-ring included
• No wiring harness, mounting bracket, or hardware included

Detailed Description

Standard Ignition AS457 is a MAP sensor used to measure manifold pressure so the engine control system can calculate load and adjust fuel delivery and ignition timing. This part cross-references Beck/Arnley 158-1061 for the same application. It is a direct-fit option for Mitsubishi Outlander, Mitsubishi Outlander Sport, Mitsubishi RVR, Mitsubishi Lancer, Mitsubishi Outlander PHEV, Mitsubishi L200, Mitsubishi Eclipse, Mitsubishi Galant, and Mitsubishi Endeavor applications listed in the fitment data. The AS457 part number is also commonly searched for Mitsubishi Outlander MAP sensor and Mitsubishi Lancer manifold absolute pressure sensor replacement needs.

What It Helps Address

• Check engine light related to manifold pressure sensor performance
• Rough idle caused by incorrect intake manifold pressure readings
• Hard starting or extended crank conditions tied to air-fuel calculation errors
• Poor throttle response from inaccurate engine load input
• Fuel trim issues caused by faulty MAP sensor signals

Installation Notes and Tips

Verify connector shape, terminal count, and vacuum port layout before installation. Inspect the intake manifold sealing surface and replace the O-ring if the original seal is damaged or contaminated. Confirm the sensor is seated fully and the electrical connector locks in place. After installation, clear diagnostic trouble codes and recheck live data to confirm stable manifold pressure readings.

Quality Assurance

Standard Ignition replacement sensors are built for service applications where accurate engine management input matters. AS457 is specified with the connector, terminal, and seal details needed for the listed Mitsubishi fitments, including 2008-2019 Mitsubishi Outlander, 2009-2017 Mitsubishi Lancer, and 2011-2019 Mitsubishi Outlander Sport and RVR applications.
