Introduction To 22204-22010 Mass Air Flow (MAF) Sensor
The 22204-22010 is a premium 5-pin drop-in Mass Air Flow (MAF) sensor. It features an integrated intake air temperature (IAT) thermistor. As a widely deployed air metering component, this sensor serves as a direct-fit replacement. It is interchangeable with part numbers 22204-22010, 22204-0C020, 22204-0D030, 22204-0J010, 22204-30010, and 22204-21010. It also cross-references numbers 197400-2000 and 197400-2030.
This sensor is widely used across extensive vehicle lineups. These include for Toyota Camry (2.4L / 3.0L / 3.3L), for Toyota Corolla (1.8L 1ZZ-FE), for Toyota RAV4, and for Toyota Tacoma (2.7L / 3.4L / 4.0L). It is also compatible with for Toyota 4Runner, for Toyota Highlander, for Lexus ES300 / ES330 / RX300 / RX330, for Scion tC / xB, and for Pontiac Vibe.
Manufactured under strict IATF 16949 quality guidelines, this sensor features a micro-machined hot-wire/hot-film sensing bypass element. It is coupled with an external amber glass-encapsulated NTC thermistor bead. By measuring instantaneous intake air mass and temperature simultaneously, the sensor delivers high-precision linear analog voltage signals (0.5V to 4.5V DC) directly to the Engine Control Module (ECM). This enables precise closed-loop air-fuel ratio modulation, optimized fuel injection pulse width, and ignition timing control.
For auto parts importers, wholesale distributors, and repair facilities, this unit effectively resolves persistent lean fault codes (P0171 / P0174). It also cures rough idling, engine hesitation, and cold-start stalling.

Professional Installation Guidelines
- Safety Preparation: Turn off the vehicle ignition and disconnect the negative battery terminal before servicing the intake system.
- Locate the Sensor: Find the 22204-22010 drop-in probe inserted into the air filter box lid or the upper intake air duct.
- Disconnect Harness: Depress the center locking tab on the 5-pin electrical connector and carefully pull to disconnect.
- Remove Fasteners: Use a Phillips screwdriver or 7mm socket to remove the two mounting screws. Gently twist and pull the sensor straight out.

FAQ
Q1: Why is the 22204-22010 sensor the primary culprit behind Lean Codes P0171 and P0174 on for Toyota and for Lexus vehicles?
Q2: Why is 22204-22010 known as the "universal drop-in MAF probe" across for Toyota and for Lexus platforms?
Older MAF sensors were built into bulky housings. The 22204-22010 introduced a modular “drop-in probe” secured by two screws into the air duct. This probe calibrates across many engine sizes, from 1.5L 4-cylinders to 4.7L V8s. It is now one of the highest-volume, fast-moving replacement parts in the global aftermarket.
Q3: What is the visible amber/brown glass bead located on the side of the 22204-22010 sensor probe?
The amber glass-encapsulated bead on the side of the probe is the integrated Intake Air Temperature (IAT) sensor (a negative temperature coefficient / NTC thermistor). While the internal hot-wire elements hidden inside the central airflow tunnel measure intake air volume mass, this external thermistor bead measures incoming air temperature.
Q4: What wholesale order terms, MOQs, packaging options, and B2B warranty are provided for global importers?
Flexible MOQ: Minimum order starting from 10 units
Custom Packaging: Neutral white/brown boxes, or customized full-color private-label branded boxes (such as YZHIDIANF) .
Laser Marking: Custom laser engraving of your company logo, part number.
Quality Assurance: airflow bench calibration backed by a comprehensive 12-month warranty.
