or
· Engine speed
lower than 1050 rpm
· Following
trouble code not stored: 21
· Intake manifold
absolute pressure lower than 14 kPa (140 mbar)
· Above
conditions must be fulfilled for at least 0.06 s.
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 the throttle valve position
Effects:
· The secondary
air injection is switched off
· The long- term
correction of the mixture adaptation is switched off
