Spectra MA216S Mass Air Flow Sensor

Spectra MA216S Mass Air Flow Sensor

The Spectra MA216S mass air flow sensor is a standard replacement part for vehicles that need accurate intake air measurement and stable engine management input. It is built with a programmable ceramic circuit board and a premium silicon coating to help resist under-hood heat swings and road vibration.

Compatible With 1999-2003 Cadillac Catera, 2000 Saturn LS2, 2000 Saturn LW2, 2001-2003 Saturn L300, and 2001-2003 Saturn LW300. This Spectra MA216S sensor uses a 5-terminal blade connection with a single oval male connector and a black plastic housing.

Key Features

• Standard replacement mass air flow sensor
• Programmable ceramic circuit board for signal consistency
• Premium silicon coating for heat and vibration resistance
• All-platinum resistance thermometer sensing elements
• 5-terminal blade design with one oval male connector
• Black plastic housing
• No housing, wiring harness, or mounting bracket included

Detailed Description

The Spectra MA216S is engineered for direct replacement use in emission control and sensor applications where the engine computer depends on precise airflow data. Its circuit design is focused on faster signal response and consistent output, while the platinum resistance thermometer sensors support accurate measurement under changing operating conditions. For drivers servicing a Cadillac Catera or Saturn L300, LW300, LS2, or LW2, this part number MA216S provides a practical OE-style sensor replacement.

This part cross-references AP Exhaust 641513 for the same application.

What It Helps Solve

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response
• Check engine light concerns related to air metering
• Fuel trim issues from incorrect sensor output
• Driveability problems tied to a worn mass air flow sensor

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This MA216S uses a single oval male connector with 5 blade terminals and does not include a housing, harness, or mounting hardware. Inspect the intake tract for contamination or air leaks before replacing the sensor, and clear diagnostic trouble codes after installation if required by the vehicle.

Quality Assurance

Spectra builds this sensor as a standard replacement component with materials selected to handle heat cycling and vibration in the engine bay. The MA216S is intended to meet the needs of routine sensor replacement on confirmed applications.
