DTC DETECTION LOGIC
NOTE:
If DTC P0222 or P0223 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643.
Refer to EC-353, "DTC Logic".
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause |
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. |
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 8 V at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
Is 1st trip DTC detected? YES >> Proceed to EC-266, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK THROTTLE POSITION SENSOR 1 POWER SUPPLY
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK THROTTLE POSITION SENSOR 1 POWER SUPPLY CIRCUIT
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK THROTTLE POSITION SENSOR 1 GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK THROTTLE POSITION SENSOR 1 INPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK THROTTLE POSITION SENSOR
Check throttle position sensor. Refer to EC-268, "Component Inspection (TP Sensor)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace electric throttle control actuator. Refer to EM-27, "Removal and Installation".
Component Inspection (TP Sensor)
1.CHECK THROTTLE POSITION SENSOR
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace electric throttle control actuator. Refer to EM-27, "Removal and Installation".
Steering switch (meter control switch) signal circuit
Diagnosis Procedure
Regarding wiring diagram information, refer to mwi-28, "wiring diagram".
1.Check combination meter input signal

Brake precautions
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping distance
will be longer.
Using the bra ...
