Introduction To 22204-30030 MAF Sensor
The 22204-30030 is an OE-standard 4-pin drop-in Mass Air Flow (MAF) sensor featuring an integrated intake air temperature (IAT) sensor engineered for modern commercial pickups, heavy-duty 4WD SUVs, passenger vans, and compact diesel vehicles for
Toyota. Serving as a direct aftermarket replacement for part number 22204-30030 and 197500-0030, including for Toyota Hilux (GUN125 / GUN126 2.4L & 2.8L), for Toyota Fortuner (GUN156 / GUN166), for Toyota Land Cruiser Prado (GDJ150 / GDJ155 2.8L D-4D), for Toyota HiAce / Granvia (GDH201 / GDH300 series), for Toyota Innova (GUN142 / GUN143), as well as for Toyota Yaris, for Toyota Auris, and for Toyota Corolla equipped with the 1.4L 1ND-TV diesel engine.
The 22204-30030 incorporates micro-machined hot-film air-mass sensing elements with an exposed fast-response NTC thermistor. By simultaneously calculating intake air mass flow and ambient intake temperature, it provides rapid, high-accuracy linear output data to the Engine Control Unit (ECU). This enables the common-rail management system to dynamically regulate high-pressure diesel injection timing, variable nozzle turbocharger (VNT) boost pressure, and Exhaust Gas Recirculation (EGR) flow rates.

Professional Installation Guidelines
- Safety Preparation: Turn off the engine ignition and disconnect the vehicle’s negative battery terminal before servicing electrical components.
- Locate the Sensor: On for Toyota Hilux, Fortuner, and Prado, locate the 22204-30030 drop-in probe inserted into the air cleaner housing lid or the upper intake duct.
- Disconnect Harness: Depress the locking clip on the 4-pin electrical connector and gently pull to disconnect.
- Remove Fasteners: Remove the two retaining screws securing the sensor flange. Gently twist and pull the probe straight out.
- Inspect & Clean Housing: Wipe clean the mounting hole in the air cleaner cover. Ensure the new Viton O-ring is seated in the sensor groove.
- Install New Sensor: Insert the new 22204-30030 probe straight into the mounting hole. Reinstall the two retaining screws and tighten securely (do not over-tighten into plastic).
- Reconnect & ECU Reset: Push the 4-pin harness connector firmly until the lock tab clicks. Reconnect the battery terminal, start the diesel engine, allow it to idle for 5–10 minutes to relearn fuel trim parameters, and clear any historical OBD trouble codes using a diagnostic scan tool.

FAQ
Q1: What specific function does the 22204-30030 MAF sensor perform on for Toyota 1GD-FTV and 2GD-FTV common-rail diesel engines?
For Toyota 2.4L 2GD-FTV and 2.8L 1GD-FTV engines (for Hilux, Fortuner, and Prado), the 22204-30030 measures intake air mass and temp. The ECM uses this data to control fuel delivery, injection timing, VNT geometry, and EGR opening. Accurate metering ensures clean combustion and prevents DPF/SCR soot buildup.
Q2: How does the 4-pin 22204-30030 differ from older 5-pin sensors (such as 22204-22010 / 22204-0L010)?
Older sensors used a 5-pin setup with separated grounds. The 22204-30030 features a streamlined 4-pin design with updated circuitry for high-speed ECUs. Its body, bypass duct, and calibration curves are specifically mapped for high-boost diesel airflow. It is not interchangeable with 5-pin sensors and must match the 4-pin vehicle harness.
Q3: What diagnostic trouble codes (DTCs) and engine symptoms are commonly caused by a contaminated or failing 22204-30030 sensor?
- P0100: Mass Air Flow (MAF) Circuit Malfunction
- P0101: Mass Air Flow (MAF) Circuit Range / Performance Problem
- P0102: Mass Air Flow (MAF) Circuit Low Input
- P0103: Mass Air Flow (MAF) Circuit High Input
- P0112 / P0113: Intake Air Temperature (IAT) Sensor Circuit Low / High Input
Q4: What precautions should be taken when installing the 22204-30030 sensor probe?
- Always inspect the pre-installed Viton rubber O-ring to ensure it is seated evenly in the probe flange groove. A damaged O-ring will allow unmetered false air to leak into the intake duct.
- Carefully insert the probe straight into the air filter housing mounting hole without forcing it against the sidewall.
- Tighten the two mounting screws securely by hand (do not over-torque to avoid stripping the plastic threads).
- Inspect and replace the engine air filter element if it is contaminated before starting the engine.
