Polaris · shared OEM table · 9 manual P/Ns
Sportsman 450 / 570 / 600 fault codes (2022–2027)
The 2022–2026 Sportsman 450 H.O. / 570, the 2022–2024 Sportsman 570 Touring / 6x6, and the 2027 Sportsman 600 manuals publish the same 70-entry diagnostic table. This page lists it once, with the manual citation for each model and the differences that matter in the garage.
Scope note
This page covers the shared 70-entry table (OEM chapter 0000632336) published in the 2022–2026 Sportsman 450 H.O. / 570, 2022–2024 Sportsman 570 Touring / 6x6, and 2027 Sportsman 600 manuals.
The machines are not identical. The table defines the codes; the hardware, trim, and model-year wiring determine which rows apply. Use the code your display shows.
The 2025–2027 Sportsman 570 / 600 Touring / X2 / 6x6 manuals use a different 180-entry table. The 2026 Sportsman 570 2-Up and the tractor / MD manuals use other tables. The 2027 Sportsman 500 has its own page.
Table profile
This page reproduces 70 entries from 9 model-year records (2022–2027), 9 manual P/Ns, and chapter 0000632336.
Rows keep the manual’s printed order, from SPN 520203 / FMI 3 to SPN 84 / FMI 8.
Every row carries an SPN/FMI pair; 33 distinct SPNs and 14 FMI values appear.
The largest FMI groups are FMI 3 (19 rows), FMI 4 (17 rows), and FMI 5 (9 rows); together they account for 64% of the table.
The most repeated SPN is 110 (Engine Temperature Sensor) with 4 rows, followed by SPN 634 with 4 rows.
Every printed SPN/FMI pair carries one title in this table.
These counts describe the rows on this page, not every manual in the archive. The source box below lists the exact citation for every record on the page.
Why five 450 / 570 years, three Touring years, and a 2027 600 share a table
Polaris reuses diagnostic chapter topic 0000632336 in the 2022–2026 Sportsman 450 H.O. / 570 manuals, the 2022–2024 Sportsman 570 Touring / 6x6 manuals, and the 2027 Sportsman 600 manual. The SPN, FMI, component, and failure labels are identical entry-for-entry. The shared table is published once here, with anchors for each model group.
The old 2022 450 / 570, 2027 600, and 2022–2024 Touring URLs redirect to those anchors. The 2023–2026 450 / 570 URLs use year-specific anchors. The table rows are the same; the P/N and model-year citation are not.
What the 70 entries cover
The table covers throttle safety, throttle position, engine temperature, AWD and Active Descent, fan relay, fuel pump driver, gear position, system voltage, and several relay and actuator circuits. Most rows are circuit faults: voltage high, voltage low, open, or grounded.
A low-voltage event can set several entries at once, especially in cold weather or after a high accessory load. The table records the labels the controller publishes; it does not identify a failed component.
What is different by model
The 2022–2026 450 H.O. and 570 are utility ATVs with AWD and ADC. The 2022–2024 Touring / 6x6 variants use the same table with their own body styles and drivelines. The 2027 Sportsman 600 is a newer machine with its own trim and running changes.
The 2025–2027 Touring / X2 / 6x6, the 2026 570 2-Up, the tractor / MD variants, and the 2027 Sportsman 500 are separate tables. Their pages carry the matching code definitions and manual citations.
How to use this page
Record the SPN and FMI, choose the model section for your machine, and use the full table or the decoder. Note the manual P/N for your model year. This page is a label index; it does not confirm a failed part or provide repair steps.

Model and year notes
These notes explain which systems matter on each machine. They do not add rows to the OEM table.
Sportsman 450 H.O. / 570 (2022–2026)
The 2022–2026 450 H.O. and 570 share this 70-entry table. The entries include AWD, ADC, fan, fuel pump, throttle safety, and gear-position circuits. The table is identical across these five model years; the manual P/N and model-year citation are not.
Sportsman 570 Touring / 6x6 (2022–2024)
The 2022 Sportsman 570 Touring / X2 / 6x6, 2023 Sportsman 570 Touring / 6x6, and 2024 Sportsman 570 Touring / 6x6 manuals publish this 70-entry table. The 2025–2027 Touring / X2 / 6x6 manuals move to a separate 180-entry table.
Sportsman 600 (2027)
The 2027 Sportsman 600 manual publishes the same 70-entry table as the 2022–2026 450 / 570. The hardware and trim differ, and the 2027 manual supplies the P/N citation. The 2027 Sportsman 500 is a separate table and a separate page.

What the FMI number means
Every entry pairs an SPN with an FMI. The FMI is the failure type; the SPN is the circuit or component.
| FMI | What it generally means |
|---|---|
| 0 | Data valid, but above the normal operating range (most severe) |
| 1 | Data valid, but below the normal operating range (most severe) |
| 2 | Data erratic, intermittent, or incorrect |
| 3 | Voltage above normal, or shorted to a high source |
| 4 | Voltage below normal, or shorted to a low source |
| 5 | Current below normal, or open circuit |
| 6 | Current above normal, or grounded circuit |
| 7 | Mechanical system not responding or out of adjustment |
| 8 | Abnormal frequency, pulse width, or period |
| 9 | Abnormal update rate |
| 10 | Abnormal rate of change |
| 11 | Root cause not known |
| 12 | Bad intelligent device or component |
| 13 | Out of calibration |
| 16 | Data valid, but above the normal operating range (moderately severe) |
| 19 | Received network data in error |
| 31 | Condition exists (manufacturer-specific) |
Reading the table
The code column gives the identifier the controller publishes: an SPN/FMI pair or a P-code. The label column gives the short condition or component/failure text from the cited OEM chapter.
A label identifies a monitored circuit or condition. It does not confirm that a named part has failed, and it does not establish whether the machine is safe to operate.
Write down the full code, the model year and model, and the conditions when it appears. That record is what the manual and a service provider use to match the entry to your machine.
Source note
This page publishes short component and condition labels from the public OEM manual chapter, not the manual's long-form repair prose. The source list below opens the exact chapter for every manual in the group.
Scope
This is a label index. It does not provide repair procedures, parts advice, or a diagnosis for a specific machine. Codes can vary by trim, market, and running changes.
Common questions
What does this Sportsman 450 / 570 / 600 table cover?
This page lists 70 code entries from the cited public OEM chapter (0000632336, 9 manual P/Ns). The table preserves the short condition or component/failure labels published in that chapter.
Where can I check the source?
The source box at the bottom of the page gives the manual P/N, the model-year coverage, and a link to the OEM chapter. The methodology page explains the site’s source and labeling rules.
