MULTIPORT FUEL INJECTION (MPI) <4G1>
13B-209
Code No. P2101: Throttle Valve Control Servo Magneto Malfunction
OPERATION
• Controls the current that is applied from the
engine-ECU (terminals No. 7, No. 22) to the elec-
tronic-controlled throttle valve (terminals No. 5,
No. 6).
FUNCTION
• Engine-ECU check whether the throttle valve
control servo magneto failed.
TROUBLE JUDGMENT
Check Conditions
• Ignition switch is in "ON" position.
• Battery voltage is more than 8.3 V.
Judgement Criterion
• Driving current of throttle valve control servo is
abnormal.
Or
• Temperature in driving circuit of throttle valve
control servo is abnormal.
PROBABLE CAUSE
• Failed throttle valve control servo.
• Open/short circuit in throttle valve control servo
circuit or lose connector contact.
• Failed engine-ECU

DIAGNOSIS PROCEDURE
STEP 1. Connector check: A-107
electronic-controlled throttle valve connector
Q: Is the check result normal?
YES :
Go to Step 2 .
NO :
Repair or replace.
STEP 2. Perform resistance measurement at
A-107 electronic-controlled throttle valve
connector.
• Disconnect connector, and measure at elec-
tronic-controlled throttle valve side.
• Resistance between terminal No. 5 and No. 6.
OK: 0.3
− 100 kΩ (at 20°C)
Q: Is the check result normal?
YES :
Go to Step 3 .
NO :
Replace throttle body assembly.
STEP 3. Connector check: A-114 engine-ECU
connector
Q: Is the check result normal?
YES :
Go to Step 4 .
NO :
Repair or replace.

STEP 4. Check harness between A-107 (terminal
No. 6) electronic-controlled throttle valve
connector and A-114 (terminal No. 7) engine-ECU
connector.
• Check output line for short circuit and damage.
Q: Is the check result normal?
YES :
Go to Step 5 .
NO :
Repair.
STEP 5. Check harness between A-107 (terminal
No. 5) electronic-controlled throttle valve
connector and A-114 (terminal No. 22)
engine-ECU connector.
• Check output line for short circuit and damage.
Q: Is the check result normal?
YES :
Go to Step 6 .
NO :
Repair.
STEP 6. Check the trouble symptoms.
Q: Is the check result normal?
YES :
Replace engine-ECU.
NO :
Intermittent malfunction (Refer to GROUP
