CmeRto Mass Air Flow Sensor MAF 22204-21010 Compatible with Toyota/Lexus 3.0L–4.0L — OEM Fit, 5-Pin Plug

The CmeRto 22204-21010 Mass Air Flow (MAF) Sensor accurately measures incoming air for proper engine fuel-air balance in compatible Toyota and Lexus 3.0L–4.0L vehicles.

This direct-replacement MAF sensor is engineered to match OEM performance for a range of Toyota and Lexus models, including Camry, Corolla, Highlander, 4Runner, Tacoma, RAV4, and select Lexus ES/RX vehicles. Built using robust materials and modern production methods, the unit aims to supply a clear, stable signal to the engine control unit (ECU) so fuel delivery and ignition timing remain consistent under normal and demanding driving conditions. Before ordering, confirm fitment using one of the listed OE cross-reference numbers to ensure compatibility with your vehicle.

How does this MAF sensor affect engine behavior?

By monitoring the volume and density of incoming air, the sensor helps the ECU calculate the correct fuel quantity for combustion. A precise airflow input reduces rough idling, hesitation on acceleration, and uneven fuel trims that can affect driveability.

• Delivers a stable electrical signal under temperature changes
• Fast response time (~15 seconds to steady reading) for dynamic conditions
• Improves throttle response and helps maintain fuel economy

Which vehicles and part numbers is this compatible with?

This replacement is intended for many Toyota and Lexus gasoline engines in the 3.0L–4.0L range. Compatibility depends on the original part number or OE cross-reference, so compare your current sensor’s number before purchasing.

• Fits models such as Camry (02–06), Corolla (03–08), Highlander (01–10), 4Runner (00–07), Tacoma (99–10), RAV4 (01–05), Lexus ES300/RX300
• Matches multiple OE references including 22204-07010, 22204-0D030, 22204-22010 and others
• Designed as a 5-pin plug replacement for direct installation

What are the build quality and performance details?

The sensor is fabricated from corrosion-resistant materials and manufactured to meet tight tolerances similar to factory units. It offers low curve deviation and consistent output so the ECU receives accurate airflow data even during high thermal stress.

• High-quality materials for durability and heat resistance
• Output curve tolerance under 2% to maintain accurate readings
• Computer-tested for signal clarity and thermal stability

How difficult is installation and what should I expect?

Installation is straightforward for home mechanics or professional shops: remove the old sensor, fit the replacement, and reconnect electricals. To clear stored fault codes, disconnect the battery ground briefly after installation; allow the engine to cool before you start work for safety.

• Simple plug-and-play replacement with a 5-pin connector
• Recommended to disconnect battery ground to reset ECU indicators
• Wait for engine to cool to avoid burns and ensure proper handling

Who is this for? This CmeRto 22204-21010 MAF sensor suits car owners and mechanics who need a cost-effective, reliable replacement for Toyota and Lexus 3.0L–4.0L engines. It’s appropriate for routine repairs, restoring proper engine behavior after a failed airflow sensor, or when diagnosing drivability issues tied to incorrect air-fuel readings. Confirm your vehicle’s original part number against the listed OE cross-references before purchase to ensure a correct fit.
