Test description
Check electropneumatic pressure converter for exhaust gas recirculation for correct pressure control. Activation takes place with the HHT tool and reading off the actual values via the vacuum tester.
Test connections
Connect the vacuum tester with Y-distributor unit between the pressure transducer Y84 and vacuum control unit for intake air throttling und EGR vacuum control unit.
Execution of the test
1. Engine running.
2 Actuate pressure transducer via the HHT and read off the display on the vacuum tester.
