BRAND NEW *OEM Quality* MAF airflow sensor to suit Land Rover Discovery 2 L318 with the Td5 2.5L turbo diesel.

If your Discovery 2 has gone sluggish when loaded up, smokes on take-off or flashes a warning light, a worn MAF sensor is a likely cause. This heavy duty fit replacement is a direct swap and ships from Melbourne.

TO SUIT

Fits the Discovery Series II Td5 from late 1998 to 2004 - engine codes 10P, 15P and 16P (102kW) in 5 and 7 seat wagons. The Discovery runs a higher output Td5 tune than the Defender, so accurate air metering matters even more. Dates are in the compatibility table.

FITMENT CHECK

This listing covers the Td5 diesel only. Match OEM MHK100620 on your existing sensor before ordering.

ABOUT THIS SENSOR

The Discovery 2 Td5 ECU leans on the MAF to meter fuel and manage EGR, and towing or a full load makes any error obvious. An under-reading sensor lets the engine overfuel, causing smoke, soot build-up and a laboured feel.

Replacing the sensor often clears intermittent limp mode that otherwise gets blamed on the turbo. This unit has a low fault rate and is matched to the OEM part number.

COMMON SYMPTOMS OF FAILURE

Check engine light - fault codes P0100 P0101 P0102 P0103 (MAF circuit)
Black smoke and soot build-up
Intermittent limp mode
Laboured towing or hill climbing
Rough idle
Increased fuel consumption

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.
