BRAND NEW *OEM Quality* mass airflow sensor to suit Land Rover Discovery L319, Range Rover L322/L320 and Freelander 2 L359 with AJV8 and AJV6 petrol engines.

MAF sensor failure on these Land Rover platforms can trigger limp mode, rough idle and poor fuel economy - often with a P0100-series fault code. This BRAND NEW direct-fit replacement restores correct air metering and ECU fuelling control without any modification. Dispatched same day from Melbourne.

TO SUIT

This sensor suits the Land Rover Discovery III L319 with the 4.4L AJV8 (2004-2009) and 4.0L Cologne V6 (2004-2009), Range Rover L322 with the 4.2L Supercharged and 4.4L AJV8 (2005-2012), Range Rover Sport L320 with the 4.2L Supercharged and 4.4L AJV8 (2005-2013), and Freelander 2 L359 with the 3.2L inline-6 (2006-2014).

ABOUT THIS SENSOR

The MAF sensor on these Land Rover models measures intake air volume and temperature, providing the ECU with the data it needs to control fuel injection and ignition timing. The sensor is a bolted insert mounted between the air filter housing and the throttle body.

A failing sensor causes the ECU to default to open-loop fuelling, producing poor idle quality, excessive fuel consumption and potential limp-mode activation on later models with torque-management calibration.

COMMON SYMPTOMS OF FAILURE

Check engine light with codes P0100 P0101 P0102 P0103
Rough idle or hunting at operating temperature
Limp mode or reduced power warning on the dash
Poor throttle response under load
Increased fuel consumption
Stalling in traffic or at low speed

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.
