Walker Products has supplied automotive fuel system and engine sensor components since 1946, with manufacturing and engineering support aimed at meeting OEM-level specifications for aftermarket service parts.

Detailed Description

This mass air flow sensor assembly is used to measure incoming air so the engine control system can calculate fuel delivery more accurately. For vehicles such as the Nissan 300ZX and INFINITI J30, a properly functioning MAF sensor helps maintain stable idle quality, throttle response, and air-fuel control. Part Number 245-1235 is also cross-referenced to Delphi AF10211 for the same application.

What It Helps Solve

• Rough idle or unstable idle speed
• Hesitation during acceleration
• Lean or rich fuel mixture concerns
• Check engine light related to airflow sensor readings
• Poor drivability caused by inaccurate intake air measurement

Installation Notes and Tips

Verify connector style, terminal count, and housing configuration before installation. This assembly does not include mounting hardware. Inspect the intake tract, air filter, and electrical connector for contamination or damage before replacing the sensor. Confirm vehicle application by year and model: Fits 1990-1996 Nissan 300ZX, N/A; Fits 1993-1995 INFINITI J30, N/A.
