The EGR solenoid valve is located in the bank of solenoids on the engine and
can be identified by the gray dab of paint on its body.
- Disconnect the vacuum sensing tubes from the solenoid valve and the vacuum
pipe.
- Blow through the solenoid valve from tube B. Air should come
out of air filter A on the valve.
- Detach the electrical connection from the EGR solenoid valve, then activate
the valve using jumper cables from the battery.
- Blow through vacuum tube B. Air should come out of port C.
- If the solenoid does not operate as indicated above, replace it.
The EGR solenoid valve is located in the bank of solenoids on the engine. It
supplies intake manifold vacuum to the EGR valve.
- Locate the EGR valve in the engine solenoid valve bank, and disconnect the
vacuum hose from the valve (see illustration).

- Blow into the solenoid valve through port B and place your
hand under the air filter. Air should pass freely through the valve and exit
from the air filter.
- Detach the connector from the solenoid valve, then connect a 12-volt power
source and a ground to the solenoid terminals. Blow through port B of
the valve and place your hand over the opening of port A. Air
should pass freely through the valve and exit through port A.
- If the air flow is not as described above, replace the solenoid valve.
