DIAGNOSTIC TROUBLE CODE (DTC) – P0400 ELECTRIC EXHAUST GAS
RECIRCULATION OUT OF LIMIT
Circuit Description
An Electric Exhaust Gas Re-circulation (EEGR) system
is used to lower oxides of nitrogen (NOX) emission lev-
els caused by high combustion temperatures. It a ac-
complishes this by feeding small amounts of exhaust
gases back into the combustion chamber. When the air/
fuel mixture is diluted with the exhaust gases, combus-
tion temperatures are reduced.
A EEGR valve is used on this system. The linear EEGR
valve is designed to accurately supply exhaust gases to
the engine without the use of intake manifold vacuum.
The valve controls exhaust flow going into the intake
manifold from the exhaust manifold fhrough an orifice
with a engine control module(ECM) controlled pintle.
The ECM controls the pintle position using inputs from
the Throttle Position (TP) and the Manifold Absolute
Pressure (MAP) sensor. The ECM then commands the
EEGR valve to operate when necessary by controlling
an ignition signal through the ECM. This can be moni-
tored on a scan tool as the Desired EEGR position.
The ECM monitors the results of its command through a
feedback signal. By sending a 5 volt reference and a
ground to the EEGR valve, a voltage signal representing
the EEGR valve pintle position is sent to the ECM. This
feedback signal can also be monitored on a scan tool
and is the actual position of the EEGR pintle. The actual
EEGR position should always be near the commanded
or Desired EEGR position.
ThisDiagnostic Trouble Code(DTC) will detect an open
or short circuit.Conditions for Setting the DTC

Engine Coolant Temperature(ECT) is higher than
80°C(176°F).

Intake Air Temperature(IAT) is higher than 15°C
(59°F).

Manifold Absolute Pressure is greater than 75kPA.

The EEGR is higher than 3%.

Mass Air Flow is between 92 ~157mg/tdc.

Engine Speed Is Between 2,500~2,900rpm.

P0341, P0342, P1671, P1672, P1673 are NOT SET.
Action Taken When the DTC Sets

The Malfunction Indicator Lamp (MIL) will illuminate.

The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.

A history DTC is stored.
Conditions for Clearing the MIL/DTC

The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.

A history DTC will clear after 40 consecutive warm-up
cycles without a fault.

DTC(s) can be cleared by using the scan tool.
