Code No. P2565: Waste Gate Position Sensor Circuit High Input
 
 
 
 
OPERATION
  • A power voltage of 5 V is applied to the electronic-controlled waste gate actuator from the engine-ECU connector terminal WGP5.
  • The power voltage is earthed to the engine-ECU connector terminal WGPG from the electronic-controlled waste gate actuator.
  • The sensor signal is inputted to the engine-ECU connector terminal WGPS from the electronic-controlled waste gate actuator output terminal.
 
 
FUNCTION
  • The waste gate position sensor converts the turbocharger waste gate regulating valve position into voltage and inputs it into the engine-ECU.
  • The engine-ECU controls the waste gate opening angle.
 
 
TROUBLE JUDGEMENT
Check Conditions
  • After 2 seconds since the ignition switch is turned ON or since the completion of engine start.
  • Battery positive voltage is more than 6 V.
Judgement Criterion
  • Waste gate position sensor output voltage is more than 4.8 V for 2 seconds.
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • Stop driving the waste gate actuator control servo.
  • Torque is restricted.
 
 
PROBABLE CAUSES
  • Failed waste gate position sensor
  • Open circuit and harness damage in waste gate position sensor circuit or loose connector contact
  • Failed engine-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE data list
  • Item 127: Waste gate position sensor
OK: Changes when the waste gate operates.
Is the check result normal?
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
Go to Step 2.
 
STEP 2. Perform resistance measurement at electronic-controlled waste gate actuator connector.
  • Disconnect connector, and measure at harness side.
  • Resistance between terminal engine-ECU WGPG line and body earth.
OK: Continuity (2 Ω or less)
Is the check result normal?
Go to Step 5.
Go to Step 3.
 
STEP 3. Check of open circuit, and damage in WGPG line between electronic-controlled waste gate actuator 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 data list
  • Item 127: Waste gate position sensor
OK: Changes when the waste gate operates.
Is the check result normal?
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
Replace the engine-ECU.
 
STEP 5. Replace the turbocharger assembly
  • After replacing the turbocharger assembly, reconfirm whether the diagnosis code is set.
Is the diagnosis code set?
Replace the engine-ECU.
Check end.
