On Board Diagnosis Logic
Malfunction is detected when ... Check Items (Possible Cause)
+An excessively high voltage from the charge air pressure sen-
sor is sent to ECM when engine is running.+Intake air system
+Turbocharger system
+Charge air pressure sensor
+Harness or connectors
(The charge air pressure sensor circuit is shorted.)
DTC Confirmation Procedure
NOTE:
If DTC 0406 ªINT AIR VOLº displayed with DTC 0905
ªTURBO PRESSUREº, perform trouble diagnosis for DTC
0905 ªTURBO PRESSUREº first. (See EC-3601.)
WITH CONSULT-II
1) Turn ignition switch ªONº.
2) Select ªDATA MONITORº mode with CONSULT-II.
3) Start engine and warm it up to normal operating temperature.
4) Drive vehicle.
5) Maintain the engine speed more than 4,000 rpm for at least
10 seconds.
6) If DTC is detected, go to ªDiagnostic Procedureº, EC-3533.
WITHOUT CONSULT-II
1) Start engine and warm it up to normal operating temperature.
2) Drive vehicle.
3) Maintain the engine speed more than 4,000 rpm for at least
10 seconds.
4) Stop vehicle.
5) Turn ignition switch ªOFFº, wait at least 5 seconds and then
turn ªONº.
6) Perform ªDiagnostic Test Mode II (Self-diagnostic results)º
with ECM.
7) If DTC is detected, go to ªDiagnostic Procedureº, EC-3533.SEF817Y

Engine coolant temperature sensor Engine coolant temperature
Ignition switch Start signal

Barometric pressure sensor (Built into

This system controls flow rate of EGR led from exhaust manifold
to intake manifold. The opening of the EGR by-pass passage in
the EGR volume control valve changes to control the flow rate.
A built-in step motor moves the valve in steps corresponding to
the ECM output pulses. The opening of the valve varies for opti-
mum engine control. The optimum value stored in the ECM is
determined by considering various engine conditions.
The EGR volume control valve remains close under the follow-
ing conditions.
+Engine stopped
+Engine starting
+Low engine coolant temperature
+Excessively high engine coolant temperature
+High engine speed
+Wide open throttle
+Low battery voltage
+Low barometric pressure
