Spectra MA136S Mass Air Flow Sensor

Spectra MA136S Mass Air Flow Sensor

The Spectra MA136S mass air flow sensor is a standard replacement part for vehicles that need accurate airflow measurement and stable engine management input. It is built with a programmable ceramic circuit board, premium-grade silicon coating, and platinum resistance thermometer sensors to help maintain signal consistency in demanding under-hood conditions.

Compatible with Hyundai Santa Fe, Hyundai Sonata, Kia Magentis, and Kia Optima applications, this Spectra MA136S sensor supports reliable airflow data for drivability and emissions control.

Key Features

• Standard replacement mass air flow sensor for emission control systems
• Programmable ceramic circuit board for consistent signal output
• Premium-grade silicon coating helps protect the circuit board from heat and vibration
• Platinum resistance thermometer sensor design for faster response
• Black plastic housing with one oval male connector
• 5-terminal blade connection layout
• No housing, wiring harness, mounting bracket, or mounting hardware included

Detailed Description

The Spectra MA136S is engineered as a direct-fit style mass air flow sensor for 1999-2005 Hyundai Sonata, 2001-2006 Hyundai Santa Fe, 2001-2005 Kia Optima, and 2003-2005 Kia Magentis applications. It measures incoming air so the engine control system can calculate fuel delivery and maintain proper air-fuel balance. The sensor’s ceramic circuit board and protective silicon coating are intended to improve durability in high-temperature engine bays and against road vibration. This part cross-references Delphi AF10355 and NTK MG0047 for the same application.

Common Issues This Part May Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response during acceleration
• Check engine light related to mass air flow sensor performance
• Fuel trim problems from incorrect air measurement
• Reduced drivability in Hyundai Sonata, Hyundai Santa Fe, Kia Optima, or Kia Magentis models

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This MA136S uses a single oval male connector with 5 blade terminals and does not include a housing or wiring harness, so the existing vehicle connector and intake setup must match. Inspect the intake tract for contamination, loose clamps, or air leaks before replacing the sensor, since those conditions can affect airflow readings.

Quality Assurance

Spectra builds this sensor with materials and circuit protection intended for stable operation in demanding under-hood environments. The MA136S is a standard replacement part designed to meet the needs of the listed Hyundai and Kia applications.
