DTC SET CONDITIONS
Logic Flow Chart
 
 
Check Conditions
  • The engine coolant temperature is higher than 78°C (172°F) engine stop in previous Drive Cycle <Up to 18 Model year>
  • The engine coolant temperature is higher than 77°C (171°F) engine stop in previous Drive Cycle <From 19 Model year>
  • The engine coolant temperature - fuel tank temperature is between -5°C (-23°F) and 5°C (41°F) when the ignition on.
  • Battery positive voltage is higher than 10 volts.
Judgment Criterion
  • The intake air temperature sensor 1 output - intake air temperature sensor 2 output is less than -19°C (-2°F) or higher than 32°C (90°F) when the ignition on.
note
  • Monitoring stops when the fuel tank temperature at ignition on - fuel tank temperature* is 3°C (37°F) or more.
  • *: Fuel tank temperature until 600 seconds accumulated with vehicle speed 40 km/h (25 mph) or more.
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • None.
 
 
OBD-II DRIVE CYCLE PATTERN
  • Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 5 .
 
 
TROUBLESHOOTING HINTS (The most likely causes for this code to be set are:)
  • Intake air temperature sensor 1 circuit harness damage, or connector damage.
  • Intake air temperature sensor 2 circuit harness damage, or connector damage.
  • Intake air temperature sensor 1 failed.
  • Intake air temperature sensor 2 failed.
  • ECM failed.
 
 
DIAGNOSIS
STEP 1. Using scan tool (M.U.T.-IIISE), check data list item 5: Intake Air Temperature Sensor 1.
cautionTo prevent damage to scan tool (M.U.T.-IIISE), always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool (M.U.T.-IIISE).
(1) Connect scan tool (M.U.T.-IIISE). Refer to HOW TO CONNECT THE SCAN TOOL (M.U.T.-IIISE) .
(2) Remove the mass airflow sensor from the air cleaner cover.
(3) Turn the ignition switch to the "ON" position.
(4) Set scan tool (M.U.T.-IIISE) to the data reading mode for item 5, Intake Air Temperature Sensor 1.
(5) Heating the sensor using a hair drier.
  • The indicated temperature increases.
    noteDo not allow it to increase over 80°C (176°F).
(6) Turn the ignition switch to the "LOCK" (OFF) position.
(7) Attach the mass airflow sensor.
Is the sensor operating properly?
Go to Step 2.
Refer to DTC P0111 - Intake Air Temperature Circuit Range/Performance Problem (sensor 1) .
 
STEP 2. Using scan tool (M.U.T.-IIISE), check data list item DE: Intake Air Temperature Sensor 2.
(1) Remove the boost pressure sensor from the charge air cooler outlet air pipe.
(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool (M.U.T.-IIISE) to the data reading mode for item DE, Intake Air Temperature Sensor 2.
(4) Heating the sensor using a hair drier.
  • The indicated temperature increases.
    noteDo not allow it to increase over 80°C (176°F).
(5) Turn the ignition switch to the "LOCK" (OFF) position.
(6) Attach the boost pressure sensor.
Is the sensor operating properly?
It can be assumed that this malfunction is intermittent. Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions .
Go to Step 3.
 
STEP 3. Check the intake air temperature sensor 2.
Refer to Intake Air Temperature Sensor 2 Check .
Is the measured resistance at the standard value?
Go to Step 4.
Replace the boost pressure sensor. Then go to Step 8.
 
STEP 4. Check the continuity at boost pressure sensor harness side connector.
(1) Disconnect the boost pressure sensor connector and measure at the harness side.
(2) Check for the continuity between terminal E line and ground.
  • Continuity (2 ohms or less)
Does continuity exist?
Go to Step 6.
Go to Step 5.
 
STEP 5. Check of harness damage in E line between boost pressure sensor connector and ECM connector.
Is the harness wire in good condition?
Go to Step 7.
Repair the connector(s) or wiring harness. Then go to Step 8.
 
STEP 6. Check of harness damage in UATS line between boost pressure sensor connector and ECM connector.
Is the harness wire in good condition?
Go to Step 7.
Repair the connector(s) or wiring harness. Then go to Step 8.
 
STEP 7. Using scan tool (M.U.T.-IIISE), check data list item DE: Intake Air Temperature Sensor 2.
(1) Turn the ignition switch to the "ON" position.
(2) Set scan tool (M.U.T.-IIISE) to the data reading mode for item DE, Intake Air Temperature Sensor 2.
  • The intake air temperature and temperature shown with the scan tool should approximately match.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Is the sensor operating properly?
It can be assumed that this malfunction is intermittent. Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions .
Replace the ECM (Refer to Removal and Installation ). Then go to Step 8.
 
STEP 8. 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 5 .
(2) Check the diagnostic trouble code (DTC).
Is DTC P2199 set?
Retry the troubleshooting.
The inspection is complete.
