EGR Control Solenoid: Testing and Inspection

EGR SOLENOID VALVE INSPECTION

EGR Solenoid Valve (Vacuum)

1. Remove the EGR solenoid valves. (See VACUUM HOSE ROUTING DIAGRAM [KL].) (See VACUUM HOSE ROUTING DIAGRAM [KJ].)







2. Apply battery positive voltage to terminal A and ground terminal B of the EGR solenoid valve (vacuum). Verify that air flows as shown.
- If not as specified, replace the EGR solenoid valve (vacuum).

EGR Solenoid Valve (Vent)

1. Remove the EGR solenoid valves. (See VACUUM HOSE ROUTING DIAGRAM [KL].) (See VACUUM HOSE ROUTING DIAGRAM [KL])







2. Verify that air flows as shown.
- If not as specified, replace the EGR solenoid valve (vent).







3. Apply battery positive voltage to terminal A and ground terminal B of the EGR solenoid valve (vent). Verify that air flows as shown below.
- If not as specified, replace the EGR solenoid valve (vent).
