PACKAGE INCLUDES

1 x BRAND NEW mass airflow sensor insert. 5-pin oval connector. 12V operating voltage. Hot-wire sensor type. Installs into original housing - no housing replacement required. We recommend replacing the air filter at the same time as sensor replacement.

ABOUT THIS SENSOR

The mass airflow sensor on Toyota petrol and hybrid engines is a hot-wire type insert sensor positioned in the intake between the air filter housing and the throttle body. It measures the volume and temperature of intake air and transmits this data to the ECU, which uses it to calculate precise fuel injection quantity and ignition timing. On hybrid models the ECU also uses this data to manage the transition between electric and petrol drive modes. This sensor covers a wide range of Toyota engine families sharing a common MAF insert specification - including the 2ZR-FE and 2ZR-FXE used in the Corolla and Prius, the 2AR-FE and 2AR-FXE used in the Camry and RAV4, and the 2GR-FE and 1GR-FE used in the Aurion, Kluger and Land Cruiser Prado. Verified fitment against Toyota OEM 22204-37010 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 engine hunting at operating temperature
Hesitation or flat spot on acceleration
Poor fuel economy - noticeably increased consumption
Hybrid drive mode switching rough or erratic
Engine stalling at idle or in slow traffic
Limp mode or reduced power

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.
