BRAND NEW *OEM Quality* mass airflow sensor (insert type) to suit Lexus petrol and hybrid models. Covers the CT 200h, ES 300h/350, GS 250/350/300h/450h, IS 200t/250/300/300h/350, NX 200t/300h, RC 200t/350, RX 270/350/450h and LFA. Stocked in Melbourne and dispatched express Australia-wide.

On Lexus hybrid and petrol models, the MAF sensor is essential for both accurate fuel metering and seamless electric-to-petrol transition. When it degrades the symptoms are subtle at first - a slight roughness at idle, mild hesitation - but escalate to check engine lights, poor fuel economy and limp mode. Lexus owners expect better. This BRAND NEW direct-fit insert replacement restores factory precision and smooth Lexus performance. Same-day dispatch from Cranbourne VIC.

ABOUT THIS SENSOR

The mass airflow sensor on Lexus models shares the same Toyota/Lexus platform insert specification across all compatible engine families. It is a hot-wire type sensor measuring the volume and temperature of intake air and transmitting this data to the ECU for fuel injection and ignition timing calculation. On hybrid models including the CT 200h, GS 300h/450h, ES 300h, IS 300h and RX 450h, this data also governs the transition between electric and petrol drive modes - meaning sensor accuracy directly affects the smoothness of the hybrid drive experience. Verified fitment against Lexus/Toyota OEM 22204-0T040 and DENSO DMA-0111.

COMMON SYMPTOMS OF A FAILING MAF SENSOR

Check engine light - fault codes P0100 P0101 P0102 P0103 (MAF sensor circuit)
Rough idle or hunting at operating temperature
Hesitation or loss of refinement under acceleration
Hybrid drive transition rough or jerky
Noticeably increased fuel consumption
Limp mode or reduced power warning
Engine stalling at idle

Can I clean my MAF sensor instead of replacing it?

Yes - if the sensor is contaminated rather than electrically failed, cleaning with a dedicated MAF sensor cleaner spray can restore correct readings. Do not use brake cleaner or generic electrical contact cleaner as these leave residue that damages the sensing wire. Allow the sensor to dry completely before reinstalling. If cleaning does not resolve the fault codes, the sensor requires replacement.

What is the difference between a MAF sensor and a MAP sensor?

A MAF (Mass Air Flow) sensor directly measures the mass of air entering the engine using a hot wire element in the intake. A MAP (Manifold Absolute Pressure) sensor measures intake manifold pressure to calculate air density. Most modern engines use one or the other - some use both. Your vehicle service manual or OBD2 fault codes will confirm which sensor type your engine uses.

Will a faulty MAF sensor cause my vehicle to fail an emissions test?

Yes. A faulty MAF sensor causes the ECU to miscalculate fuel delivery, typically resulting in a rich running condition that increases CO and hydrocarbon emissions. Most roadworthy and emissions checks will fail a vehicle with an active MAF sensor fault code or visibly excessive exhaust smoke.

What are the symptoms of a bad MAF sensor?

Common symptoms include rough idle, hesitation or stumbling on acceleration, poor fuel economy, black smoke from the exhaust, and an illuminated Check Engine light. Your ECU may log fault codes P0100 to P0104.

Can I drive with a faulty MAF sensor?

You can drive short distances but it is not recommended. A faulty MAF sensor causes the ECU to run incorrect fuel mixtures, which can damage the catalytic converter and O2 sensors over time. Have it replaced as soon as possible.

How do I test if my MAF sensor is bad?

Use an OBD2 scanner to check for fault codes P0100-P0104. You can also use a multimeter or live data scanner to check the sensor output voltage against your vehicle's specification. A reading significantly outside spec confirms a faulty sensor.

What causes a MAF sensor to fail?

The most common causes are a dirty or contaminated sensing element (often from a missing or damaged air filter), oil contamination from an over-oiled aftermarket air filter, heat damage, or general wear over time.

Do I need to reset my ECU after replacing the MAF sensor?

It is good practice to clear any stored fault codes using an OBD2 scanner after replacement. Some vehicles will self-adapt within a short drive cycle, but clearing codes ensures the ECU recalibrates from a clean baseline.
