EGR Valve

  1. Look through opening in EGR valve body. With engine at normal operating temperature, check that valve shaft moves when engine reaches 3000-3500 RPM under no-load condition.
    NOTE: On 2WD Federal models, engine must have been running 8 minutes or more before performing this test.
  2. If shaft does not move as specified, remove valve and manually check valve movement. If valve appears okay, check vacuum lines for leaks. If valve does not operate, clean or replace.
