Detonation Elimination Technology (DET)
The DET system prevents damage to the engine from detonation by
automatically reducing the engine timing and adding fuel whenever the
sensors detect detonation.
You may notice decreased engine RPM and performance when DET is
activated, but in most cases DET activation is temporary, and the timing
will return to normal automatically. In extreme conditions the DET
system retards timing and holds it in a retarded state. If this occurs,
replace the fuel with recommended fuel or see your POLARIS dealer
for service.
Cause of DET Activation
Poor quality fuel
Improper engine modifications
Sensor Fail-Safe
The DET includes a sensor fail-safe system to prevent the engine from
damage if the sensor fails, becomes disconnected or is unable to detect
detonation. The rider will experience a loss of power. The sensor must
be reconnected or repaired to regain full power. See your POLARIS
dealer for service if this occurs.
Tip: The check engine light will flash six times if the sensor fails or becomes
disconnected.
Solution
Replace with higher quality fuel
Do not modify the engine
