Fault setting conditions |
|
| |
Lower limit value |
- At an engine speed of 500 to 1300 rpm the vacuum must be greater than 30 to 60 mbar.
|
| |
Upper limit value |
- At a throttle flap angle greater tan about 60° the vacuum must be greater than 300 mbar.
|
| |
Order of magnitude of the intake manifold pressure |
- Vacuum of 500 to 1200 mbar; depending on performance map for motor speed and throttle flap angle.
- About 5 seconds per limit value
|
| |
Checking duration |
|
| 6 |
Check prerequisites |
- locking time after start of about 20 seconds expired
- no fault in the throttle flap angle
- after starting the engine increase engine speed at least once to over 1300 rpm.
