The ECM receives signals sent from the engine coolant tempera-
ture sensor, crankshaft position sensor (TDC), ignition switch etc.
to determine engine speed and operating conditions. Based on
these signals, the ECM controls EGRC-solenoid valve (A and B)
operation and throttle solenoid valve operation.
The EGR control stops when engine coolant temperature is below
45ÉC (113ÉF), at idling, at starting and when the system compo-
nents and engine speed signals are disordered.

Component Description
The EGRC-solenoid valves A and B, control vacuum pressure act-
ing on the EGR valve. The EGR control valve will be fully opened,
half-opened or fully closed, as required.
The throttle control solenoid valve controls vacuum pressure acting
on the throttle control valve. Thus, intake air passages are opened
or closed in relation to exhaust gas and intake air. Utilizing the
relationship between exhaust gas pressure and intake air pressure
control, the amount of EGR (exhaust gas recirculated) is regulated
in three approximate measures Ð large, medium, small.

DTC Confirmation Procedure
WITH CONSULT-II
1) Turn ignition switch and air conditioner switch to ªONº position.
2) Select ªDATA MONITORº mode with CONSULT-II.
3) Wait at least 2 seconds.
WITHOUT CONSULT-II
1) Turn ignition switch and air conditioner switch to ªONº position.
Wait at least 2 seconds.
2) Turn ignition switch to ªLOCKº position, wait at least 5 seconds
and then turn to ªONº position.
3) Perform ªDiagnostic Test Mode IIº (Self-diagnostic results).
