ApplianPar Mass Air Flow Meter (MAF) for Toyota Tacoma/4Runner/T100 — Direct-Fit Replacement, OEM Fitment 22204-75010

ApplianPar Mass Air Flow (MAF) Meter is a direct-fit replacement sensor that restores accurate airflow readings for compatible Toyota engines.

This Mass Air Flow Meter from ApplianPar swaps in for factory units to help your engine control module get correct air-intake data. It replaces Toyota part numbers 22204-75010 and 22250-0C010 and fits multiple late-1990s to early-2000s Toyota models. The unit arrives ready to install and is supplied as a single sensor in the package.

Will this sensor fit my Toyota Tacoma, 4Runner, or T100?

Yes — this MAF meter was designed to match the fitment of the original equipment for specific model years. Check the underside of your existing sensor for the part numbers listed to confirm compatibility before ordering.

• Compatible models: Toyota Tacoma 1997–2004
• Also fits Toyota 4Runner 1997–2000
• Compatible with Toyota T100 1998
• Replaces OEM numbers 22204-75010 and 22250-0C010

How straightforward is installation and what tools are needed?

Installation is typically a simple swap of the old MAF sensor for the new unit and can be completed with basic hand tools. Most jobs require disconnecting the electrical connector and a couple of screws or clamps; no special programming is necessary.

• Disconnect vehicle battery for safety before starting
• Remove intake hose clamp and electrical connector
• Unscrew mounting hardware, swap sensors, and reassemble
• No ECU reflashing required for direct-fit replacements

How does replacing the MAF sensor affect engine performance?

A correctly functioning MAF sensor gives the engine control unit the precise airflow measurement it needs to calculate fuel delivery and ignition timing. Replacing a faulty sensor can reduce rough idle, erratic acceleration, or check-engine codes related to air-metering without promising specific mileage or power improvements.

• Restores accurate airflow data to the engine control module
• Can resolve air/fuel ratio related drivability issues
• Helps clear MAF-related diagnostic trouble codes when fault is sensor-related
• Works with existing intake and wiring harness of compatible models

Who is this for: This ApplianPar MAF meter is intended for owners and mechanics of Toyota Tacoma (1997–2004), 4Runner (1997–2000), and T100 (1998) who need a direct-fit replacement for part numbers 22204-75010 or 22250-0C010. It suits DIY enthusiasts performing routine repairs, professional shops doing engine diagnostics, and anyone replacing a failing or aging mass air flow sensor to restore proper engine operation.
