Hand-held tester:

WARNING: This page is about a different variant/trim than selected.
  1. CHECK VALVE TIMING (See  REPLACEMENT  ) 
    1. Check for loose or jumped tooth of timing chain.

      OK: The matchmarks of the crankshaft pulley and camshaft pulley are alined.

    1. NG: ADJUST VALVE TIMING (See  REPLACEMENT  ) 
    2. OK: GO TO NEXT STEP. 
  2. PERFORM ACTIVE TEST USING HAND-HELD TESTER (OPERATE OF OCV) 
    1. Connect the hand-held tester to the DLC3.
    2. Start the engine and warm it up.
    3. Turn ON the ignition switch. Push the hand-held tester main switch.
    4. Enter the following menus: DIAGNOSIS/ENHANCED OBD II/ACTIVE TEST/VVT CTRL B1.
    5. Using the hand-held tester, operate the OCV and check the engine speed.

      Standard: 

      TESTER OPERATION AND CONDITION SPECIFICATIONS

      Tester Operation Specified Condition
      OCV is OFF Normal engine speed
      OCV is ON Rough idle or engine stall
    1. NG: Go to step   4 
    2. OK: GO TO NEXT STEP. 
  3. CHECK IF PTC OUTPUTS REOCCUR 
    1. Erase the DTC(s) using one of the following methods: 1) use the hand-held tester, 2) disconnect the battery cable for more than 60 seconds, or 3) remove the EFI NO. 1 and ETCS fuses for more than 60 seconds.

      HINT:

      After disconnecting the battery cable, perform the "INITIALIZE" procedure (See INITIALIZATION ).

    2. Start and warm up the engine.
    3. Drive the vehicle for 10 minutes or more.
    4. Read output DTC using the hand-held tester.

      OK: No DTC is output. 

    1. OK: VVT SYSTEM OK* 

      HINT:

      *: DTCs P0011 and P0012 are output when a foreign object in the engine oil enters the system. These codes will stay even if the system returns to normal after a short time. Foreign objects are filtered out by the oil filter.

    2. NG: GO TO NEXT STEP. 
  4. CHECK ECM (OCV SIGNAL) 
    1. During idling, check the waveform of the ECM connector using an oscilloscope.

    1. GO TO NEXT STEP. 
  8. CHECK CAMSHAFT TIMING GEAR ASSY (See  REPLACEMENT  ) 

    OK: Camshaft timing gear rotates smoothly when pressure is applied. 

    1. OK: Go to step   10 
  9. REPLACE CAMSHAFT TIMING GEAR ASSY 
    1. GO TO NEXT STEP.
