2027 Polaris Sportsman 500 fault codes
The 2027 Sportsman 500 reports diagnostics as SPN/FMI pairs. This page lists all 64 entries from the 2027 owner's manual — throttle safety, engine temperature, idle air control, chassis relay, fuel pump, fan, and gear sensor circuits.
Scope note
This is the 2027 Sportsman 500 owner's manual (P/N 9942518). The manual publishes its own table for the platform; do not carry codes over from the 570 or 850 pages.
The manual uses "Driver Circuit" labels for relay and driver faults — short to B+, grounded, or open/grounded. The label names the circuit, not a failed part.
EPS rows apply to machines equipped with electric power steering.
Table profile
This page reproduces 64 entries from the 2027 Polaris Sportsman 500 owner’s manual, manual P/N 9942518, and chapter 0001077186.
Rows keep the manual’s printed order, from SPN 630 / FMI 13 to SPN 84 / FMI 8.
Every row carries an SPN/FMI pair; 31 distinct SPNs and 14 FMI values appear.
The largest FMI groups are FMI 3 (17 rows), FMI 4 (15 rows), and FMI 2 (7 rows); together they account for 61% 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.

What the FMI number means
Every entry above 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 labels from the public OEM owner's manual chapter, not the manual's long-form repair prose. The source box below gives the exact chapter and model-year coverage.
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 2027 Polaris Sportsman 500 table cover?
This page lists 64 code entries from the cited public OEM chapter (Polaris Owner's Manual P/N 9942518 (2027 Sportsman 500) - Diagnostic Display Code Definitions). 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.
