STEP 5. Check harness between A-107 (terminal
No. 2) electronic-controlled throttle valve
connector and A-114 (terminal No. 22)
engine-ECU connector or engine-CVT-ECU
connector.
• Check output line for short circuit and damage.
Q: Is the check result normal?
YES :
Go to Step 6 .
NO :
Repair the damaged harness wire.
STEP 6. Check the trouble symptoms.
Q: Does trouble symptom persist?
YES :
Replace engine-ECU <M/T> or
engine-CVT-ECU <CVT>.
NO :
Intermittent malfunction (Refer to GROUP

Code No. P0642: Throttle Position Sensor Power Supply
FUNCTION
• The engine-ECU <M/T> or engine-CVT-ECU
<CVT> checks the throttle position sensor power
voltage for abnormal conditions.
TROUBLE JUDGMENT
Check Conditions
• Ignition switch is in "ON" position <M/T>.
• Battery positive voltage is 6.3 V or higher.
Judgement Criteria
• Throttle position sensor power voltage is 4.1 V or
less <M/T>.
• Throttle position sensor power voltage is 4.1 V or
less for 0.3 seconds <CVT>.
PROBABLE CAUSE
• Failed engine-ECU <M/T> or engine-CVT-ECU
<CVT>
DIAGNOSIS
STEP 1. Check the trouble symptoms.
Q: Does trouble symptom persist?
YES :
Replace engine-ECU <M/T> or
engine-CVT-ECU <CVT>.
NO :
Intermittent malfunction (Refer to GROUP
00
− How to Use
Troubleshooting/Inspection Service Points
−
How to Cope with Intermittent Malfunctions

Code No. P0657: Throttle Valve Control Servo Relay Circuit Malfunction
OPERATION
• Battery voltage is applied to the throttle valve
control servo relay terminal (terminal No. 3).
• Battery voltage is applied to the throttle valve
control servo relay terminal (terminal No. 1) from
the engine control relay (terminal No. 4).
• The engine-ECU <M/T> or engine-CVT-ECU
<CVT> (terminal No. 123) applies current to the
throttle valve control servo relay coil by turning
ON the power transistor in the unit in order to turn
the relay ON.
