2012 Polaris Ranger 800 XP Error Codes & Solutions
How to Retrieve Error Codes
- Turn the ignition key to the “ON” position.
- If there’s an active issue, the “Check Engine” light will illuminate.
- Error codes can be accessed by pressing the “MODE” or “SET” button until the code appears.
- Codes usually display as “SPN: XXXX FMI: XX.”
- SPN = Suspect Parameter Number (system/component)
- FMI = Failure Mode Indicator (type of fault)
- Codes usually display as “SPN: XXXX FMI: XX.”
Common Error Codes Table
SPN | FMI | Meaning | Likely Cause | Solution |
---|---|---|---|---|
27 | 3 | TPS (Throttle Position Sensor) circuit high | Faulty sensor, wiring issue | Inspect/replace TPS; check connections |
27 | 4 | TPS circuit low | Shorted/grounded wire, bad TPS | Replace TPS or repair wiring |
51 | 3 | Cylinder 1 misfire | Bad spark plug, coil, injector | Replace spark plug; check coil/injector |
51 | 5 | Cylinder 1 open circuit | Damaged wiring, plug, or coil | Inspect wiring; replace as needed |
84 | 4 | Low voltage to fuel pump | Weak battery, bad connection | Charge/replace battery; check wiring |
52 | 3 | Injector 1 circuit high | Bad injector or open/short wire | Test injector; repair/replace |
52 | 4 | Injector 1 circuit low | Short circuit in injector/wiring | Repair wiring; replace as nec. |
110 | 3 | Intake air temp sensor high | Faulty sensor or corrosion | Replace sensor; check connection |
110 | 4 | Intake air temp sensor low | Faulty sensor, poor connection | Replace/repair as needed |
105 | 3/4 | MAP sensor high/low | Bad sensor, vacuum leak | Replace sensor; check hoses/connections |
520207 | 5 | ECU Power Relay low/open | Bad relay or connection | Replace relay; check wiring |
3056 | 2/4/5 | Battery voltage low/high | Alternator or battery issue | Test/replace battery, alternator |
Code Reading Example
If you see “SPN: 27 FMI: 3” on your dash:
- SPN 27 = Throttle Position Sensor
- FMI 3 = Voltage above normal or shorted to high source
- Solution: Inspect and replace the TPS or check wiring/connectors for corrosion or damage.
General Notes
- Most error codes are related to sensors: TPS, MAP, Injector, Air Temp, etc.
- Battery voltage or power relay errors often signal charging system or wiring issues.
- If persistent codes remain after replacing parts, always check or reset connectors and battery voltage first.
Clearing Codes
- Codes usually clear automatically after the fault is resolved (except some “historic” codes which can be cleared by disconnecting the battery for 10-30 minutes or using a Polaris diagnostics tool).
Summary Table
Code Example | What it Means | What to Do |
---|---|---|
SPN 51 FMI 3 | Cylinder misfire | Check plugs/coils/injector |
SPN 27 FMI 4 | TPS signal too low | Inspect/replace throttle sensor/wiring |
SPN 110 FMI 3 | Air temp sensor out of range | Inspect sensor and replace if necessary |
SPN 3056 FMI 2 | Battery voltage too low | Test battery/alternator, check connections |
