Inspection Procedure 7: Engine Does Not Revolve Up
 
 
 
 
COMMENTS ON TROUBLE SYMPTOM
  • The failure could possibly be caused by the failed electronic-controlled throttle valve system, faulty fuel system, defective ignition system and so on.
 
 
PROBABLE CAUSES
  • Failed ignition system
  • Failed fuel system
  • Failed electronic-controlled throttle valve system
  • Timing chain in out of place
  • Failed CVT <CVT>
  • Failed engine-ECU
 
 
DIAGNOSIS PROCEDURE
note<CVT>
To protect the CVT, the CVT-ECU outputs, into the engine-ECU, the request signal to reduce the engine torque according to the operation condition. Based on the signal, the engine-ECU closes the throttle valve, retards the ignition or carries out fuel cut. At that time, the engine output seems to temporarily reduce, but there is no malfunction.
STEP 1. M.U.T.-IIISE diagnosis code
Is the diagnosis code set?
Inspection chart for diagnosis code (Refer to ).
NO : Go to Step 3 <M/T>.
NO : Go to Step 2 <CVT>.
 
STEP 2. M.U.T.-IIISE other system diagnosis code
noteWhen the CVT has a malfunction, the CVT-ECU might output the request signal of reducing the engine torque in order to protect the CVT.
  • Confirm whether the diagnosis code is set in the CVT-ECU.
Is the diagnosis code set?
Perform troubleshooting of CVT System (Refer to GROUP 23A - Troubleshooting - Diagnosis Code Chart ).
Go to Step 3.
 
STEP 3. M.U.T.-IIISE data list
  • Data list reference table (Refer to ).
    1. Item 11: Accelerator pedal position sensor (main)
    2. Item 12: Accelerator pedal position sensor (sub)
    3. Item 13: Throttle position sensor (main)
    4. Item 15: Throttle position sensor (sub)
Are the check results normal?
Go to Step 4.
Perform the diagnosis code classified check procedure for the sensor that has shown an abnormal data value. Inspection chart for diagnosis code (Refer to ).
 
STEP 4. Check timing mark on the timing chain.
Is the check result normal?
Go to Step 5.
Align the timing marks.
 
STEP 5. Visual check of ignition spark.
  • Remove the spark plug and install it to the ignition coil.
  • Connect the ignition coil connector.
  • Disconnect all injector connectors.
  • At the engine start, check each spark plug produces a spark.
Is the check result normal?
Go to Step 6.
Check Inspection Procedure - ignition circuit system (Refer to ).
 
STEP 6. Fuel pressure measurement.
  • Fuel pressure test (Refer to ).
Is the check result normal?
Replace the engine-ECU.
Repair.
