ECU Service

Never attempt to disassemble the ECU. It is sealed to prevent
damage to internal components. Warranty is void if the case is
opened or tampered with in any way.

All operating and control functions within the ECU are pre-set.
No internal servicing or readjustment may be performed. If a
problem is encountered, and you determine the ECU to be
faulty, contact the Polaris Service Department for specific
handling instructions. Do not replace the ECU without factory
authorization.

The relationship between the ECU and the throttle position
sensor (TPS) is very critical to proper system operation. If the
TPS is faulty, or the mounting position of the TPS to the throttle
body is altered, the TPS must be re-initialized.

For the purpose of troubleshooting, a known-good ECU from
another Polaris 

RANGER

 XP EFI of the same model may be

used without system or engine component damage.

ECU Replacement

1.

Remove the retaining screws (2) holding the ECU.

2.

With the Ignition turned off, disconnect the wire harness
from the ECU.

3.

To install, reverse the procedures and tighten screws to
specification.

FUEL PUMP

Operation Overview

NOTE:  All EFI units utilize quick connect lines.

An electric fuel pump assembly is used to transfer fuel to the EFI
system from inside the fuel tank. This assembly includes the fuel
pump, regulator and fuel gauge sender. The pump is rated for a
minimum output of 25 liters per hour at 39 psi and has a non-
serviceable internal 60-micron filter.

When the key switch is turned to "ON", the ECU activates the
fuel pump, which pressurizes the system for start-up.

The ECU switches off the pump preventing the continued
delivery of fuel in these instances:

• If the key switch is not promptly turned to the "start" 

position.

• If the engine fails to start, or

• If the engine is stopped with the key switch "on" (as in 

the case of an accident)

In these situations, the “check engine” light will go on, but will
turn off after 4 cranking revolutions if system function is OK.
Once the engine is running, the fuel pump remains on.
