· Full load enrichment not activated
· Following trouble codes not stored: 21,
22
· Intake manifold absolute pressure
higher than 98.5 kPa
· Above conditions must be fulfilled for
at least 2.5 s

manifold pressure equals 90 kPa
· Engine running: The control
unit calculates the intake manifold pressure depending on the engine speed
and throttle valve position
Effects:
