BRAND NEW *OEM Quality* mass airflow sensor (insert type) to suit Volvo models fitted with compatible engine families. Covers the S80 II, V70 III and V40 fitted with the 2.5L T and 2.5T FlexFuel petrol engines, and the V40 T4/T5 variants. Stocked in Melbourne and dispatched express Australia-wide.

A failing MAF sensor on a Volvo causes the ECU to lose accurate air mass data, resulting in rough idle, increased fuel consumption, hesitation and check engine lights with MAF fault codes P0100 to P0103. This BRAND NEW direct-fit insert replacement restores factory air metering precision. Same-day dispatch from Cranbourne VIC.

TO SUIT

Suits Volvo models fitted with compatible 2.5L turbocharged petrol engine families. The S80 II covers the 2.5T and 2.5T FlexFuel Sedan from March 2006 to December 2012. The V70 III covers the 2.5T, 2.5T FlexiFuel and 2.0 BiFuel Estate from August 2007 to December 2015. The V40 Hatchback covers the T4 and T5 variants from December 2012 to December 2015. The V40 Cross Country covers the T4 AWD and T5 AWD from October 2012 to December 2016. Full vehicle list in the compatibility table above.

FITMENT CHECK

This is an INSERT TYPE sensor - it fits into the original housing which is retained. Confirm the Volvo OEM part number 31380619 on your existing sensor before ordering. This sensor is cross-compatible with the Toyota/Lexus/Suzuki/Mitsubishi platform - the Volvo OEM number 31380619 is a valid cross-reference to Toyota 22204-37010 and DENSO DMA-0111.

ABOUT THIS SENSOR

The mass airflow sensor on compatible Volvo models is a hot-wire insert type sensor shared with the Toyota/Lexus/Suzuki/Mitsubishi platform. It measures the volume and temperature of intake air and transmits this data to the ECU for fuel injection and ignition timing calculation. The Volvo OEM part number 31380619 cross-references directly to Toyota 22204-37010 and DENSO DMA-0111 - the same sensor insert specification. Verified fitment against Volvo OEM 31380619.

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
Noticeably increased fuel consumption
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.
