Spectra MA383 Mass Air Flow Sensor

Spectra MA383 Mass Air Flow Sensor

The Spectra MA383 mass air flow sensor is a direct-fit emission control component for Jeep applications that need accurate airflow measurement and stable signal output. It is built with a programmable ceramic circuit board and a premium silicon coating to help protect the sensor from under-hood heat swings and road vibration.

Compatible With 2005-2017 Jeep Liberty and 2007-2017 Jeep Wrangler applications, this sensor supports consistent engine management performance when the original MAF sensor is failing or reading inaccurately.

Key Features

• Mass air flow sensor for emission control and engine air measurement
• Programmable ceramic circuit board construction
• Premium silicon coating for added protection against heat and vibration
• Uses platinum resistance thermometer sensor technology for faster signal response
• Direct replacement for Jeep Wrangler and Jeep Liberty applications
• Part number MA383 for catalog and service reference

Detailed Description

The Spectra MA383 is engineered to measure incoming air volume so the engine control system can calculate fuel delivery more accurately. Its circuit design is focused on quicker signal response and consistent output, while the platinum resistance thermometer sensors support stable airflow readings. This part cross-references Delphi AF10508 for the same application. It also cross-references Mopar 53013733AB for select Jeep applications.

Fits 2007-2017 Jeep Wrangler, N/A. Fits 2007-2013 Jeep Liberty, N/A. Fits 2005-2006 Jeep Liberty, N/A; notes indicate compatibility with multiple mass air flow sensors.

Common Problems This Part Can Address

• Rough idle caused by inaccurate airflow readings
• Check engine light related to mass air flow sensor faults
• Hesitation or poor throttle response during acceleration
• Fuel trim issues from incorrect air measurement
• Driveability problems after sensor contamination or electrical failure

Installation Notes and Tips

Verify the connector style and OE part number before installation, especially on 2005-2006 Jeep Liberty models noted as using multiple mass air flow sensor options. Inspect the intake tract for leaks, dirt, or oil contamination before replacing the sensor. Clear diagnostic trouble codes after installation and confirm airflow data with a scan tool during a road test.

Quality Assurance

Spectra uses a protected circuit-board design and platinum resistance sensing elements to support reliable signal performance in demanding under-hood conditions.
