Fuel Shutoff Mode

The PCM has the ability to completely turn all the injectors Off or selectively turn Off some of the injectors when certain conditions are met. These fuel shut-off modes allow the powertrain to protect itself from damage and also improve its driveability.

The PCM will disable all eight injectors under the following conditions:
^ Ignition Off-Prevents engine run-on
^ Ignition On but no ignition reference signal- Prevents flooding or backfiring
^ High engine speed-Above red line
^ High vehicle speed-Above rated tire speed
^ Extended high speed closed throttle coastdown- Reduces emissions and increases engine braking

The PCM will selectively disable up to four injectors under the following conditions:
^ Torque management enabled-Transaxle shifts or abusive maneuvers
^ Traction control enabled-In conjunction with front brakes applying
^ Low coolant condition-Protects engine from overheating
