Diagnosis conditionCold condition
Signal (terminal)—
ThresholdThere is a gap between angle of target and phase-control angle degree when the engine is in a cold condition.
Diagnosis delay time—
 
 
POSSIBLE CAUSE A
  • Intake valve timing control actuator
  • Intake valve timing control motor
  • Camshaft sprocket (INT)
  • Wear or damage of the electric intake valve timing control actuator brush
  • Center target
 
 
POSSIBLE CAUSE B
  • Accumulation of debris to the signal plate of the camshaft
  • Timing chain installation
 
 
FAIL-SAFE
Engine operating condition in fail-safe mode
Fail safe modeVehicle behavior
Device fix mode
  • This mode fixes the electric IVT motor and the EVT control solenoid valve in the reference position.
  • The intake manifold runner control valve motor is turned OFF (intake manifold runner control valve opens).
  • A control signals is not transmitted to EGR volume control valve and the EGR volume control is deactivated.
 
 
DTC Confirmation Procedure
1.PRECONDITIONING
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is 10 V or more at idle.
With M.U.T.-III SE
  1. Turn ignition switch OFF and wait at least 10 seconds.
  2. Turn ignition switch ON.
  3. Turn ignition switch OFF and wait at least 10 seconds.
  4. Turn ignition switch ON.
  5. On the M.U.T.-III SE screen, select “ENGINE” >> “DATA MONITOR” >> “COOLANT TEMP/S”.
  6. Check “COOLANT TEMP/S” indication value.
With GST
Follow the procedure “With M.U.T.-III SE” above.
Is the value of “COOLANT TEMP/S”−5°C (23°F) and 45°C (113°F)?
.
-1 [if it is below −5°C (23°F)]Warm up the engine until the value of “COOLANT TEMP/S” indicates −5°C (23°F) and 45°C (113°F). And then .
-2 [if it is above 45°C (113°F)]Cool the engine down to the value of “COOLANT TEMP/S” indicates −5°C (23°F) and 45°C (113°F). And then .
 
2.PERFORM DTC CONFIRMATION PROCEDURE
  1. Turn ignition switch OFF and wait at 10 seconds.
  2. Turn ignition switch ON.
  3. Set the selector lever in N range.
  4. Start the engine and let it idle for 20 seconds or more.
  5. Check 1st trip DTC.
Is 1st trip DTC detected?
