EGR PRESSURE TRANSDUCER INSPECTION

INSPECT
^ Filter for contamination and damage (clean filter, using compressed air).
^ Remove Exhaust Gas Recirculation (EGR) pressure transducer and plug nozzle with your finger. Blow air into another nozzle and check that air passes through to a filter side freely.
^ Vacuum pump to nozzle "P" and plug nozzle "Q" with your finger. While blowing air into nozzle "A," operate vacuum pump and check that vacuum is applied to pressure transducer. If EGR pressure transducer fails tests, replace EGR pressure transducer.
