EGR Backpressure Transducer: Testing and Inspection
1) Check filter for contamination and damage. Using compressed air, clean filter.
2) Remove EGR pressure transducer and plug nozzle with finger. Blow air into another nozzle and check that air passes through to air filter side
freely.
3) Connect vacuum pump gauge to nozzle "P" and plug nozzle "Q" with finger. While blowing air into nozzle "A", operate vacuum pump gauge
and check that vacuum is applied to pressure transducer. Then stop blowing nozzle "A" and check that vacuum pump gauge indicates "0"
(zero). If check result is not satisfactory, replace EGR pressure transducer.
4) After checking, install pressure transducer and connect hoses securely.
