EGR System Test (Sidekick & Tracker '89-'95)

  1. Hoist vehicle so that rear wheels rotate freely.
  2. Set M/T or A/T in "Neutral" and transfer in "2H".
  3. Start engine, release parking brake lever and check that rear propeller shaft (tires) is turning.
  4. Warm up engine to normal operating temperature and race it after warming up. Then check to be sure that diaphram moves to open valve during acceleration and closes valve during deceleration.

    If EGR valve fails to operate properly, check vacuum hoses, EGR valve, EGR modulator, EGR SV valve, wire harness and ECM.

  5. Keep engine running at idle speed and open EGR valve by hand, and engine should either stop or reduce its speed. If neither occurs, EGR passage is clogged.
