Code No. P2101: Throttle Valve Control Servo Magneto Malfunction
OPERATION
• Controls the current that is applied from the
engine-ECU <M/T> or engine-CVT-ECU <CVT>
(terminals No. 7, No. 22) to the electronically con-
trolled throttle valve (terminals No. 1, No. 2).
FUNCTION
• The engine-ECU <M/T> or engine-CVT-ECU
<CVT> check whether the throttle valve control
servo magneto failed.
TROUBLE JUDGMENT
Check Conditions
• Ignition switch is in "ON" position <M/T>.
• Battery positive voltage is more than 8.3 V.
Judgement Criteria
• Driving current of throttle valve control servo is
abnormal <M/T>.
or
• Temperature in driving circuit of throttle valve
control servo is abnormal <M/T>.
• The coil temperature of the throttle valve control
servo is 180
°C or higher for 0.8 second <CVT>.
PROBABLE CAUSES
• Failed throttle valve control servo
• Open/short circuit in throttle valve control servo
circuit or lose connector contact
• Failed engine-ECU <M/T> or engine-CVT-ECU
<CVT>

YES :
Go to Step 5 .
NO :
Repair the damaged harness wire.
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: Is the check result normal?
YES :
Replace engine-ECU <M/T> or
engine-CVT-ECU <CVT>.
NO :
Intermittent malfunction (Refer to GROUP

Code No. P2108: Throttle Valve Control Servo Processor Malfunction
FUNCTION
• The engine-ECU <M/T> or engine-CVT-ECU
<CVT> checks the throttle valve control servo
processor for abnormal conditions.
TROUBLE JUDGMENT
Check Conditions
• Ignition switch is in "ON" position.
• Throttle position sensor (main) output voltage is
between 0.2 and 4.8 V.
• The power supply voltage of the throttle valve
control servo is more than 6 V <CVT>.
Judgement Criterion
• Malfunction of the throttle position sensor (main)
input interface.
PROBABLE CAUSE
• Failed engine-ECU <M/T> or engine-CVT-ECU
<CVT>
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-III diagnosis code.
Q: Is any other diagnosis code than P2108 output?
YES :
Inspection chart for diagnosis code (Refer
to
NO :
Replace engine-ECU <M/T> or
engine-CVT-ECU <CVT>.

13A-201
Code No. P2122: Accelerator Pedal Position Sensor (Main) Circuit Low Input
OPERATION
• A power voltage of 5 V is applied to the accelera-
tor pedal position sensor (terminal No. 1) from the
engine-ECU <M/T> or engine-CVT-ECU <CVT>
(terminal No. 85).
• The power voltage is earthed to the engine-ECU
<M/T> or engine-CVT-ECU <CVT> (terminal No.
84) from the accelerator pedal position sensor
(terminal No. 2).
• The sensor signal is inputted to the engine-ECU
<M/T> or engine-CVT-ECU <CVT> (terminal No.
83) from the accelerator pedal position sensor
output terminal (terminal No. 3).
FUNCTION
• The accelerator pedal position sensor (main) out-
puts voltage which corresponds to the accelera-
tor pedal depression.
• The engine-ECU <M/T> or engine-CVT-ECU
<CVT> checks whether the voltage is within a
specified range.
TROUBLE JUDGMENT
Check Condition
• Ignition switch is in "ON" position.
Judgment Criteria
• Accelerator pedal position sensor (main) output
voltage is 0.2 V or less <M/T>.
• Accelerator pedal position sensor (main) output
voltage is 0.2 V or less for 1.0 second <CVT>.
