Fail Safe
- Intake manifold pressure sensor process: Estimate the pressure from the engine speed and size of the throttle opening. When the throttle opening is also NG, fix at 66.7 kPa (500 mmHg, 19.69 inHg).
- Heavy fuel judgment: Not allowed to carry out the heavy judgment.
- Fuel cut control: Fuel cut will operate at engine high speed.
- EVAP cone, learning (fuel): Not allowed to learn.
- Knocking compensation
When normal: Learning ignition advance angle value = knock F/B advance angle + entire learning advance angle value + proportional learning advance angle value
Failure: learned ignition advance value = -6°CA. (6°CA retard)
Knock F/B advancing angle = 0°CA
Whole learning prohibited
proportional learning prohibited
- ISC control: ISC feedback amount calculation prohibited
Amount of ISC open-loop compensation = Fixed at 6.82%
- Purge control: Not allowed to purge.
