STEP 1. Using scan tool (M.U.T.-IIISE), check data list item 2: Crankshaft Position Sensor.
STEP 2. Using scan tool (M.U.T.-IIISE), check data list item 5: Intake Air Temperature Sensor 1.
STEP 3. Using scan tool (M.U.T.-IIISE), check data list item 6: Engine Coolant Temperature Sensor.
STEP 4. Using scan tool (M.U.T.-IIISE), check data list item 10: Mass Airflow Sensor.
(1) Start the engine and run at idle.
(2) Set scan tool (M.U.T.-IIISE) to the data reading mode for item 10, Mass Airflow Sensor.
(3) Warm up the engine to normal operating temperature: 80°C to 95°C (176°F to 203°F).- The standard value during idling should be between 800 and 1,120 millivolts.
- When the engine is revved, the mass airflow rate should increase according to the increase in engine speed.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is the sensor operating properly?
Go to Step 5. Refer to DTC P0102 - Mass Airflow Circuit Low Input , DTC P0103 - Mass Airflow Circuit High Input .
STEP 5. Using scan tool (M.U.T.-IIISE), check data list item 26: Long-Term Fuel Trim.
STEP 6. Using scan tool (M.U.T.-IIISE), check data list item 28: Short-Term Fuel Trim.
STEP 7. Visual check of ignition spark.
(1) Remove the spark plug and install it to the ignition coil.
(2) Connect the ignition coil connector.
(3) Disconnect all injector connectors.
(4) At the engine start, check each spark plug produces a spark.
Did it spark?
Go to Step 8. Refer to Inspection Procedure - Ignition Circuit System .
STEP 8. Check the injector.
STEP 9. Check air intake from intake hose and intake manifold.
STEP 10. Check the fuel pressure.
STEP 11. Check for skipped timing chain teeth.
STEP 12. Check the compression.
STEP 13. Replace the ECM.
STEP 14. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 17 . (2) Check the diagnostic trouble code (DTC).
Is DTC P0300 set?
Retry the troubleshooting. The inspection is complete.
