BRAND NEW *OEM Quality* mass airflow sensor to suit Volvo S60, S80, V50, V70, XC60, XC70, XC90, C30 and C70 with 2.4L and 2.5L five-cylinder petrol and turbo engines.

Volvo MAF sensor failures on these platforms cause rough idle, poor throttle response and increased fuel consumption - and will often set a P0100-series fault code. This BRAND NEW direct-fit unit restores accurate air metering with no wiring modification required. Australian owned and operated - stocked in Melbourne and dispatched express Australia-wide.

TO SUIT

This sensor suits a wide range of Volvo five-cylinder models including the XC70 with the 2.4L B5244T3 turbo (2000-2002), and other S60 S80 V50 V70 XC60 XC90 C30 and C70 variants fitted with the 2.4L/2.5L five-cylinder petrol engine. See full vehicle list above.

PACKAGE INCLUDES

1 x BRAND NEW mass airflow sensor (5-pin rectangular connector, without housing/insert only).

ABOUT THIS SENSOR

The MAF sensor on the Volvo five-cylinder petrol platform measures the volume and density of air entering the engine so the ECU can control injection pulse width and boost pressure (on turbocharged variants) simultaneously. The 12V bolted-mount insert features an integrated air temperature element.

A failing sensor causes the ECU to default to conservative fuelling, leading to rough idle, poor turbo response, flat acceleration and increased fuel consumption across the Volvo five-cylinder range.

COMMON SYMPTOMS OF FAILURE

Check engine light with codes P0100-P0103 (MAF circuit)
Rough idle or lean hunting at operating temperature
Flat throttle response and poor turbo spool
Hesitation under load on acceleration
Increased fuel consumption
Engine stalling at idle when warm

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.
