STEP 3. Check for open circuit to ground between the intake (1) Disconnect the intake air temperature sensor A-07 and the A-07 harness ZK603171AA00 2 1 3 4 (2) Check for the continuity between the intake air temperature ⦆ Not continuity. Q:Is the harness wire in good condition? YES: Go to Step 4. NO: Repair it. Then go to Step 5. STEP 4. Check the intake air temperature sensor. (1) Disconnect the intake air temperature sensor connector (2) Remove the mass airflow sensor. ZK603210AA00 1 2 3 4 Intake air temperature (3) Measure the resistance between intake air temperature ZK603211AA00 Mass airflow Intake air (4) Measure resistance while heating the sensor using a hair Standard value: 13 - 17 kΩ [at -20°C (-4°F)] Q:Is the measured resistance at the standard value? YES: Replace the mass airflow sensor. Then go to Step 5. NO: Go to Step 5. STEP 5. Test the OBD-II drive cycle. (1) Carry out a test drive with the drive cycle pattern. Refer to (2) Check the diagnostic trouble code (DTC). Q:Is DTC P0112 set? YES: Replace the ECM. When the ECM is replaced, register the ID code. Refer to GROUP 42B, ID Code Registration MULTIPORT INJECTION SYSTEM (MFI) <DIAGNOSIS> 13Ab-151 DIAGNOSTIC TROUBLE CODE PROCEDURES |
