Code No. P2101: Throttle Valve Control Servo Magneto Malfunction
 
 
 
 
OPERATION
  • Controls the current that is applied from the engine-ECU connector terminals ETV+, ETV- to the electronic-controlled throttle valve.
 
 
FUNCTION
  • Engine-ECU check whether the throttle valve control servo magneto failed.
 
 
TROUBLE JUDGEMENT
Check Condition
  • Battery positive voltage is more than 8.3 V.
Judgement Criterion
  • When overcurrent flows in the throttle valve control servo.
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • Throttle opening degree position is in default position.
 
 
PROBABLE CAUSES
  • Failed throttle valve control servo.
  • Short circuit or harness damage in throttle valve control servo circuit or lose connector contact.
  • Failed engine-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. Check throttle valve control servo itself.
  • Throttle valve control servo check (Refer to ).
Is the check result normal?
Go to Step 2.
Replace the throttle body assembly.
 
STEP 2. Check of short circuit, and damage in ETV+ line between electronic-controlled throttle valve connector and engine-ECU connector.
Is the check result normal?
Go to Step 3.
Repair the connector(s) or wiring harness.
 
STEP 3. Check of short circuit, and damage in ETV- line between electronic-controlled throttle valve connector and engine-ECU connector.
Is the check result normal?
Go to Step 4.
Repair the connector(s) or wiring harness.
 
STEP 4. M.U.T.-IIISE diagnosis code
  • Reconfirmation of diagnosis code.
Is the diagnosis code set?
Replace the engine-ECU.
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
