STEP 1. Using scan tool (M.U.T.-IIISE), check data list item 5: Intake Air Temperature Sensor 1.
STEP 2. Check the intake air temperature sensor 1.
STEP 3. Measure the sensor supply voltage at mass airflow sensor harness side connector.
(1) Disconnect the mass airflow sensor connector and measure at the harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal ATS line and ground.- Voltage should be between 4.5 and 4.9 volts.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is the measured voltage between 4.5 and 4.9 volts?
Go to Step 6. Go to Step 4.
STEP 4. Check of open circuit in ATS line between mass airflow sensor connector and ECM connector.
STEP 5. Using scan tool (M.U.T.-IIISE), check data list item 5: Intake Air Temperature Sensor 1.
STEP 6. Check the continuity at mass airflow sensor harness side connector.
STEP 7. Check of open circuit and harness damage in AFSE line between mass airflow sensor connector and ECM connector.
STEP 8. Check of harness damage in ATS line between mass airflow sensor connector and ECM connector.
STEP 9. 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 1 . (2) Check the diagnostic trouble code (DTC).
Is DTC P0113 set?
Retry the troubleshooting. The inspection is complete.
