stymart Mass Air Flow (MAF) Sensor for Toyota & Lexus 2006–2018 Direct-Fit Replacement, OE Cross-Refs

The stymart mass air flow (MAF) sensor is a direct-fit replacement sensor that measures intake air to help your Toyota, Lexus or Scion engine control systems calculate fuel delivery and engine management.

This high-quality MAF sensor is built to match OEM fit and function for many Toyota, Lexus and Scion models from the mid-2000s through late 2010s. It replaces multiple OE part numbers (including 197-6110, 197400-5150 and 22204-0H010) and is manufactured from durable ABS plastic and metal components. Before installation, always power down the vehicle ECU to avoid electrical faults. The unit ships as a ready-to-install module with a precise connector and mounting points engineered to eliminate modification.

Which vehicles and OE numbers does this MAF sensor replace?

This sensor is compatible with a long list of Toyota, Lexus and Scion applications—covering models such as Camry, Corolla, RAV4, Highlander, Prius families, Sienna, 4Runner, Avalon and multiple Lexus IS, ES and RX models. The product is listed to replace many factory numbers so you can match it against your vehicle's OEM part.

• Common OE references: 197-6110, 1976110, 197400-5150, 22204-0H010 and 22204-31020.
• Other cross-references included: 15J08, 2134300, 19204726, 13800-54L00 and more.
• Major compatible models: 2007–2017 Camry, 2009–2018 Corolla, 2006–2018 RAV4, 2007–2012 ES350, 2007–2012 RX350, plus many Prius and Highlander variants.

How does this MAF sensor install and what should I prepare?

Installation is designed to be a straightforward, bolt-in replacement with the same mounting points and electrical connector as the original unit. No cutting or splicing is required when matched to the correct OE number and model years.

• Turn vehicle ignition off and disconnect the battery before beginning.
• Unplug the factory MAF connector, remove mounting screws, and swap the sensor.
• Reattach connector and secure mounting screws to factory torque specifications.
• Clear any stored ECU codes and confirm proper idle and drivability after installation.

What materials, testing and quality standards does stymart use?

The stymart MAF sensor combines engineered ABS housings with metal internals and undergoes strict quality checks during production. Units are tested for fit, signal accuracy and connector reliability to meet or exceed typical OEM tolerances.

• Durable ABS plastic body with corrosion-resistant metal components.
• Bench-tested for electrical signal consistency and connector fit.
• 3D-scan development ensures direct-fit without trimming or adapters.

What does this sensor do and why replace it?

The MAF sensor measures the amount and sometimes the temperature of incoming air so engine controls can determine correct fuel injection and emissions strategies. Replacing a faulty MAF restores accurate air measurement, which helps engine management systems run more predictably.

• Provides the ECU with the airflow signal used to calculate injector pulse widths.
• Helps maintain smoother idle and consistent throttle response when functioning correctly.
• Direct replacement reduces risk of vacuum leaks or connector issues from improper aftermarket adapters.

Who is this for? If you own a compatible Toyota, Lexus or Scion listed above and your diagnostics point to a MAF-related fault code, weak performance, or irregular idle, this stymart replacement offers a cost-effective, OEM-style solution. It's aimed at DIY mechanics and professional technicians who need a reliable, ready-to-fit sensor that matches common OE numbers and covers many model years without modification.
