Replacement
value:
· Engine not
running: Intake 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:
· The secondary air
injection system is switched off
· The mixture adaptation
long term correction is switched off
