Repair procedures (plant/service)

  1. Visual inspection of vacuum sensor plug contacts
  2. Check wiring between vacuum sensor and DME
  3. Check induction system/crankcase for leaks (crankcase vacuum control can allow excess air from the crankcase to flow into the intake manifold, for instance, if vacuum line from brake booster to vacuum pump is leaking)
