Plugged Exhaust Passage

With EGR valve removed, plug intake manifold side passage using a suitable plug. Start engine and listen for exhaust noise. If no exhaust gas escapes from open EGR port, exhaust passage is plugged.

1. By grounding ALDL test terminal "B", EGR solenoid should energize and allow vacuum to be applied to gauge. Vacuum at gauge may or may not slowly bleed off; however, gauge is able to read amount of vacuum being applied.
2. When ALDL test terminal is ungrounded, gauge vacuum should bleed off through a vent in solenoid. Pump gauge vacuum may or may not bleed off; this does not indicate a problem.
3. This test determines if electrical control part of system is at fault or if connector or solenoid is at fault.
4. EGR valves used with this engine are stamped "P" for positive backpressure or "N" for negative backpressure. Proceed to appropriate chart for valve being tested.
