OBD0317A
The EGR valve is situated between the exhaust manifold
and intake manifold. After opening EGR solenoid valve,
EGR valve is opened for receiving throttle port pressure on
diaphragm. Then, part of the exhaust gas is recirculated
into intake manifold.
DTC DETECTING CONDITION:
Two consecutive trips with fault
TROUBLE SYMPTOM:
Poor driving performance on low engine speed
1.Check transmission type.
AT
MT
Check AT/MT identification circuit.
[T11BN0].>
2.Check DTC P0105, P0106, P0403, P1102 on
display.
3.Check vacuum hose.
4.Check operation of EGR system.
Confirmation of actual driving
pattern
CAUTION:
Before confirmation of actual driving pattern, conduct
CLEAR MEMORY and INSPECTION MODES.

AC: DTC P0403
—EXHAUST GAS RECIRCULATION CIRCUIT
MALFUNCTION (EGRSOL)—
OBD0324A
DESCRIPTION:
The EGR solenoid valve is situated between the BPT and
EGR valve. EGR solenoid valve is opened by a signal
emitted from the ECM. Therefore, throttle port pressure is
transmitted to diaphragm of EGR valve.
DTC DETECTING CONDITION:
Two consecutive trips with fault
TROUBLE SYMPTOM:
Poor driving performance on low engine speed
1.Check transmission type.
AT
MT
Check AT/MT identification circuit.
2.Check output signal from ECM.
3.Check harness.
4.Check harness.
5.Check EGR solenoid valve.
6.Check power supply to EGR solenoid valve.
CAUTION:
After repair or replacement of faulty parts, conduct
CLEAR MEMORY and INSPECTION MODES.
