Note. EGR systems contain different components depending on application. (Scheme 9) When testing EGR system and components, use proper illustration to determine component location.
Note. When performing EGR system test, it may be necessary to monitor engine RPM by using scan tool. For scan tool connections, see IDLE SPEED & MIXTURE in ADJUSTMENTS article.
