Common Problems and Solutions

1. Hard Starting or No Start

  • Causes: Weak battery, failing fuel pump, dirty air or fuel filters, fouled spark plugs, stale fuel.
  • Solutions:
  • Replace or recharge the battery.
  • Inspect and replace fuel and air filters.
  • Use fresh fuel only.
  • Clean or replace spark plugs.

2. Rough Idle or Loss of Power

  • Causes: Clogged fuel injectors, dirty throttle body, old fuel, bad spark plugs.
  • Solutions:
  • Use fuel injector cleaner, clean throttle body.
  • Routinely replace spark plugs.
  • Keep fuel fresh and use recommended octane.

3. Overheating

  • Causes: Low coolant, clogged radiator, faulty thermostat or water pump, radiator fan failure.
  • Solutions:
  • Check and refill coolant.
  • Clean radiator and cooling fins regularly.
  • Inspect thermostats and fans, replace if necessary.

4. Transmission and Shifting Issues

  • Causes: Low transmission fluid, worn drive belt, linkage misalignment.
  • Solutions:
  • Keep transmission fluid at recommended levels.
  • Inspect/replace CVT belt if worn/slipping.
  • Adjust linkage per owner’s manual instructions.

5. 4WD/AWD Not Engaging

  • Causes: Faulty AWD switch or sensors, broken front differential components, wiring/electrical problems.
  • Solutions:
  • Test switches and replace if faulty.
  • Inspect front differential and electrical connections.

6. Electrical Problems (Lights, Accessories, Ignition)

  • Causes: Blown fuses, corroded connections, weak battery, relay faults.
  • Solutions:
  • Replace fuses, clean and tighten connections, test/replace relays and battery as needed.

7. Suspension Squeaks and Noises

  • Causes: Dry/bad bushings, loose bolts, worn shocks.
  • Solutions:
  • Lubricate suspension points, tighten all bolts, replace bushings/shocks as needed.

2012 Polaris Ranger 800 XP Error Codes & Solutions

How to Retrieve Error Codes

  1. Turn the ignition key to the “ON” position.
  2. If there’s an active issue, the “Check Engine” light will illuminate.
  3. 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)

Common Error Codes Table

SPNFMIMeaningLikely CauseSolution
273TPS (Throttle Position Sensor) circuit highFaulty sensor, wiring issueInspect/replace TPS; check connections
274TPS circuit lowShorted/grounded wire, bad TPSReplace TPS or repair wiring

5202075ECU Power Relay low/openBad relay or connectionReplace relay; check wiring
30562/4/5Battery voltage low/highAlternator or battery issueTest/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).
