EGR Pressure Transducer

  1. Remove 3 vacuum hoses from EGR pressure transducer. Place finger over one of 2 ports on top of EGR pressure transducer and blow into the opposite port. If air passes through filter part of pressure transducer, go to next step. If air does not pass through filter part, replace pressure transducer.
  2. Connect a vacuum pump to one of 2 ports on top of pressure transducer and plug opposite port. Blow into bottom port and apply vacuum. While blowing into bottom port vacuum should be shown on vacuum pump gauge. Stop blowing into bottom port and vacuum should be zero. If vacuum can not be obtained or does not release, replace EGR pressure transducer.
