DTC P0400 EXHAUST GAS RECIRCULATION FLOW
CIRCUIT DESCRIPTION
The EGR system recirculates exhaust gases, and which is controlled to the proper volume to be suited every
driving condition. The recirculated gas mingles with the intake air, therefore the EGR system can slow down
engine combustion and let the combustion temperature down. This helps reduce a NOx emission.
In order to increase a circulatory efficiency, the ECM adjusts the lift amount of the EGR valve and intake
shutter valve (throttle valve).

MONITOR DESCRIPTION
When the target and actual positions of the EGR valve is different, the ECM interprets this as malfunction
of the EGR valve and illuminates the CHK ENG.

MONITOR DESCRIPTION
When starting a cold engine, the ECM supplies current to the glow plug for a certain period of time. As supply-
ing the current to the glow plug is terminated, the large current is suddenly cut off, therefore the battery volt-
age then varies and also the output (duty ratio) from terminal M of the generator (alternator) varies. If these
variations are not occurred when the glow plug is turned from ON to OFF, or vice versa, the ECM judges the
current has not been supplied to the glow plug, and interprets this as open malfunction of the glow plug or
glow plug circuit.
