DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 11 V at idle.
>> GO TO 2.
2.
PERFORM DTC CONFIRMATION PROCEDURE
1.
Turn ignition switch OFF and wait at least 10 seconds.
2.
Start engine and let it idle for at least 30 seconds.
3.

ECM-246, "Diagnosis Procedure"
.
NO-1
>> To check malfunction symptom before repair: Refer to
GI-41, "Intermittent Incident"
.
NO-2
>> Confirmation after repair: INSPECTION END
Diagnosis Procedure
INFOID:0000000010702949
1.
CHECK FUEL INJECTOR
ECM-372, "Component Function Check"
.

DTC detecting condition
P0201
INJECTOR CIRC-CYL1
ECM detects No. 1 injector circuit is open or shorted.
P0202
INJECTOR CIRC-CYL2
ECM detects No. 2 injector circuit is open or shorted.
P0203
INJECTOR CIRC-CYL3
ECM detects No. 3 injector circuit is open or shorted.
P0204
INJECTOR CIRC-CYL4
ECM detects No. 4 injector circuit is open or shorted.
Engine operating condition in fail-safe mode
Fail safe mode
Vehicle behavior
Traveling con-
trol mode
Accelerator an-
gle variation
control
ECM controls the accelerator pedal depression speed to make it slower than actual speed. This
causes a drop in accelerating performance and encourages the driver to repair malfunction.
NOTE:
ECM does not control the accelerator pedal releasing speed.
Combustion
control mode
Stratified charge
combustion
control at start-
ing
No stratified charge combustion at starting (cold start).

DTC detecting condition
P0222
TP SEN 1/CIRC-B1
(Throttle/pedal position sensor/switch “B”
circuit low)
An excessively low voltage from the TP sensor 1 is sent to ECM.
P0223
TP SEN 1/CIRC-B1
(Throttle/pedal position sensor/switch “B”
circuit high)
An excessively high voltage from the TP sensor 1 is sent to ECM.
Engine operating condition in fail-safe mode
Fail safe mode
Vehicle behavior
Others
• The ECM controls the electric throttle control actuator in regulating the throttle opening in order
for the idle position to be within +10 degrees.
• The ECM regulates the opening speed of the throttle valve to be slower than the normal con-
dition. So, the acceleration will be poor.
NOTE:
If throttle position sensor1 and 2 malfunction at the same time conducts following control.
• ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed
opening (approx. 5 degrees) by the return spring.
