TRITON MQ · 4N15 FIVE-PIN INSERT SELECTION
A sensor described for “Triton” may appear beside parts for several engines and series. For the MQ insert covered here, identify the 4N15 vehicle application first. Then compare the original reference, five-pin socket and mounting features without borrowing fitment from a broader online heading.
Start with series, engine and body configuration
Keep the VIN and actual build month with the MQ designation, 4WD dual-cab body and confirmed 4N15 engine. These details establish the selection being considered. A registration year or “2.4 diesel” description alone does not settle the original sensor variant.
The linked MQ sensor page excludes earlier ML/MN 4D56 and 4M41 applications, petrol models and the later MR series. Those exclusions describe this listing’s boundaries; they should not be replaced by an assumption that every model named in a supplier’s broader heading is covered.
Preserve the complete original reference
Record the original 1525A033 number and photograph any additional readable markings. A genuine-part catalogue can establish the identity of a reference, but a global list of model names is not, by itself, an exact Australian build and engine match.
If the original carries another number, request a confirmed replacement relationship for the actual vehicle. Do not treat several cross-references copied from a marketplace listing as proof of interchangeability. Tell the supplier if an engine, intake or wiring assembly has previously been changed.
Verify five visible contacts and the socket form
The supplied insert has five visible pins. Count the metal contacts in the actual close-up, then compare the socket’s locating shape and the original vehicle plug. Five contacts are a useful physical checkpoint, not evidence that every five-pin sensor shares the same application.
A connector mismatch needs to be resolved before ordering. This guide supplies no pinout, wiring adaptor or conversion method. Where access is limited, start with the available records and have the workshop photograph the original contact arrangement during its assessment.
Check what the insert includes and what it leaves out
The actual gallery shows the probe, two metal mounting eyelets and sealing ring. Compare these features with the original from corresponding angles. The surrounding air duct housing is not part of the supplied package, so a complete housing assembly is a different contents comparison.
| Comparison | Information to retain |
|---|---|
| Electrical end | Original reference, five visible contacts and socket form. |
| Mounting end | Two eyelets, sealing-ring area and original mounting arrangement. |
| Probe and surrounding duct | Overall sensor form and the existing housing, photographed separately where practical. |
Intake hoses, wiring harness and vehicle mounting screws are also excluded. Ask the installer which surrounding components can be retained and what additional items are needed. The photograph does not establish a mounting dimension, electrical value or an installation setting that is absent from the listing.
Use the correct service path for a running concern
A warning light, reduced performance or a MAF-related code does not by itself prove that this insert has failed. Diagnosis should establish the repair requirement separately from the fitment check. A physically suitable replacement is not a guarantee that a particular symptom will disappear.
Follow the vehicle-specific workshop information for assessment and installation. This article does not prescribe probe cleaning, an unplugging test, an ECU reset or any emissions-system alteration. Its purpose is to help identify the correct part once the service requirement is known.
Frequently asked selection questions
Can I choose an MR listing for an MQ car?
Do not extend this page’s application on that basis. The selected product is restricted to the MQ range above. A broader or different listing needs its own confirmed reference and vehicle match.
What should I send for confirmation?
Supply the VIN, build month, MQ 4WD dual-cab and 4N15 details, full original markings, and clear connector, probe and mounting photographs. Mention intake, engine or wiring changes.
Reference basis and current product
The genuine Mitsubishi 1525A033 airflow-sensor record corroborates original part identity. The manufacturer’s detailed application and independent Australian 4N15 catalogue entry provide the application context used for this narrower selection.
Review the current MQ product page for its complete boundaries and actual photographs. Resolve an uncertain reference or connector before ordering.
