- Turn engine off. Disconnect EGR electrical connector. Using Tool Kit (J-35616), install jumper harness connector to EGR electrical connector terminal "D" to terminal "D" of EGR valve. Connect jumper to ground. Start engine. Engine RPM should change as each EGR valve terminal "A", "B" or "C" is contacted.
- If engine RPM does not change, check for restriction in EGR supply tube or plugged EGR valve orifice. If EGR valve is not restricted or plugged, replace EGR valve. If engine RPM changes, EGR valve is okay. If further testing is required, see the appropriate COMPONENT TESTING article in the EMISSION section.
