Keep your engine's fuel metering accurate with the Standard Ignition Mass Air Flow Sensor MAS0144. It installs as a direct-fit replacement for the 2000-2002 Infiniti G20, 2000-2001 Infiniti I30, 2000-2001 Nissan Maxima, and 2000-2001 Nissan Sentra.
A mass air flow sensor measures the amount of air entering the intake so the engine control module can calculate the correct amount of fuel to deliver. When the original sensor drifts or fails, the computer works from bad data and driveability suffers.
- Measures intake airflow: reports incoming air to the ECU so it can trim the fuel delivery for the current operating conditions.
- Direct-fit replacement: designed to replace the original sensor on the listed applications.
- Helps restore the airflow signal: gives the ECU an accurate reading again when a worn or contaminated sensor is the cause of the problem.
Signs the MAF sensor may need replacing include rough idle, hesitation, stalling, poor fuel economy, or a check engine light. Because these symptoms can have other causes, diagnose the fault before replacing. If a failed mass air flow sensor is confirmed as the cause, this unit replaces it.
Manufacturer part number MAS0144.
