DTC Inspection Priority ChartINFOID:0000000012431344
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
P060A
ECM NOTE:
Fail-safe may not occur depending on malfunction type.
• ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (Approx. 5 decrees) by the return spring.
• The position of the following commponents is fixed.
- Intake valve timing control solenoid valve
- Exhaust valve timing control solenoid valve
• Engine torque may be limited.
• ASCD operation may be deactivated.
P0643
ECM • ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (Approx. 5 decrees) by the return spring.
• The position of the following commponents is fixed.
- Intake valve timing control solenoid valve
- Exhaust valve timing control solenoid valve
P0643 Sensor power supply ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P1720 Vehicle speed sensor ECM operates active grille shutter to fully-open position.
P1805 Brake switch ECM controls the electric throttle control actuator by regulating the throttle opening to a
small range.
Therefore, acceleration will be poor.
Vehicle condition Driving condition
When engine is idling Normal
When accelerating Poor acceleration
P2100
P2103 Throttle control motor relay ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2101 Electric throttle control function ECM stops the electric thro ttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2118 Throttle control motor ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2119 Electric throttle control actuator (When electric throttle control actuator does not function properly due to the return sp ring
malfunction:)
ECM controls the electric throttle actuator by regulating the throttle opening around the
idle position. The engine speed will not rise more than 2,000 rpm.
(When throttle valve opening angle in fail safe mode is not in specified range:)
ECM controls the electric throttle control actuator by regulating the throttle opening to 20
degrees or less.
(When ECM detects the throttle valve is stuck open:)
While the vehicle is driving, it slows down gradually by fuel cut. After the vehicle stops, the
engine stalls.
The engine can restart in the Neutral position, and engine speed will not exceed 1,000 rpm
or more.
P2122
P2123
P2127
P2128
P2138 Accelerator pedal position sen-
sor
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
condition.
So, the acceleration will be poor.
DTC No. Detected items

Driving long distances naturally affect fuel gauge level.
This diagnosis detects the fuel gauge malfunction of the gauge not moving even after a long distance has
been driven.
DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-329, "
Component Function Check".
Use component function check to check the overall func tion of the fuel level sensor function. During this
check, a 1st trip DTC might not be confirmed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Proceed to EC-330, "
Diagnosis Procedure".

1.PRECONDITIONING
WARNING:
When performing following procedure, be sure to observe the handling of the fuel. Refer to GI-24,
"General Precautions".
TESTING CONDITION:
Before starting component function check, preparation of draining fuel and refi lling fuel is required.
Do you have CONSULT?
YES >> GO TO 2.
NO >> GO TO 3.
2.PERFORM COMPONENT FUNCTION CHECK
With CONSULT
NOTE:
Start from step 10, if it is possible to confirm that the fuel cannot be drained by 30 (7-7/8 US gal, 6-5/
8 Imp gal) in advance.
1. Prepare a fuel container and a spare hose.
2. Release fuel pressure from fuel line, refer to EC-137, "
Work Procedure".
3. Remove the fuel feed hose on the fuel level sensor unit.
4. Connect a spare fuel hose where the fuel feed hose was removed.
5. Turn ignition switch OFF and wait at least 10 seconds then turn ON.
6. Select “FUEL LEVEL SE” in “DATA MONI TOR” mode of “ENGINE” using CONSULT.
7. Check “FUEL LEVEL SE” output voltage and note it.
8. Select “FUEL PUMP RELAY” in “ACTIV E TEST” mode of “ENGINE” using CONSULT.
9. Touch “ON” and drain fuel approximately 30 (7-7/8 US gal, 6-5/8 Imp gal) and stop it.

If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnorma lly high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to CO-9, "
Refilling". Also,
replace the engine oil. Refer to LU-8, "
Refilling".
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to use coolant with the proper mixture ratio. Refer to MA-12, "
Anti-Freeze Coolant Mixture Ratio".
2. After refilling coolant, run engine to en sure that no water-flow noise is emitted.
DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-366, "

NOTE:
Use component function check to check the overall function of the cooling fan. During this check, a DTC might
not be confirmed.

WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.

2.CHECK THROTTLE CONTROL MOTOR
RELAY INPUT SIGNAL CIRCUIT-I
1. Disconnect ECM harness connector.
2. Disconnect IPDM E/R harness connector F115.
3. Check the continuity between ECM harness connector and IPDM E/R harness connector.
4. Also check harness for short to ground and short to power.
Is the inspection result normal?
YES >> GO TO 4.
NO >> GO TO 3.
3.DETECT MALFUNCTIONING PART
Check the following.
• IPDM E/R connector F42
• Harness for open or short between IPDM E/R and ECM
>> Repair open circuit or short to ground or short to power in harness or connectors.
4.CHECK FUSE
1. Disconnect 20 A fuse (No. 53) from IPDM E/R.
2. Check 20 A fuse for blown.
Is the inspection result normal?
YES >> GO TO 9.
NO >> Replace 20 A fuse.
5.CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL CIRCUIT-I
1. Check voltage between ECM harness connector and ground under the following conditions.
Is the inspection result normal?
YES >> GO TO 8.
NO >> GO TO 6.
6.CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL CIRCUIT-II
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Disconnect IPDM E/R harness connector F42.
4. Check the continuity between ECM harness connector and IPDM E/R harness connector.
5. Also check harness for short to ground and short to power.
Is the inspection result normal?
YES >> GO TO 8.
NO >> GO TO 7.
