Note: The following procedures will allow a basic operational test of the EGR system. Since the EGR operation is controlled by the ECM, refer to COMPUTERIZED ENGINE CONTROLS for further information concerning testing of the systems operation.
1. Disconnect the vacuum hose (green stripe) from the throttle body and connect a vacuum pump to the free end of the hose.
2. While the engine is cold (coolant temperature less than 50 degrees C or 122 degrees F) apply vacuum at idle and note that vacuum leaks.
3. Allow the engine to warm up (coolant temperature greater than 85 degrees C or 185 degrees F).
4. Apply 45 mm Hg or 1.7 in. Hg of vacuum while the engine is at idle and note that vacuum is held.
5. Apply 215 mm Hg or 8.5 in. Hg of vacuum while the engine is at idle and note that the idle becomes unstable.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
