Scheme 106

1. The Intake Air Temperature (IAT) sensor, mounted on the Mass Air Flow (MAF) meter, monitors the IAT. The IAT sensor has a built-in thermistor with a resistance that varies according to the temperature of the intake air. When the IAT is low, the resistance of the thermistor increases. When the temperature is high, the resistance drops. These variations in resistance are transmitted to the ECM as voltage changes ( see scheme 1in (Scheme 106) ).
2. The IAT sensor is powered by a 5 V supply from the THA terminal of the ECM, via resistor R.
3. Resistor R and the IAT sensor are connected in series. When the resistance value of the IAT sensor changes, according to changes in the IAT, the voltage at terminal THA also varies. Based on this signal, the ECM increases the fuel injection volume when the engine is cold to improve driveability.

Scheme 108

1. The Intake Air Temperature (IAT) sensor, mounted on the Mass Air Flow (MAF) meter, monitors the IAT. The IAT sensor has a built-in thermistor with a resistance that varies according to the temperature of the intake air. When the IAT is low, the resistance of the thermistor increases. When the temperature is high, the resistance drops. These variations in resistance are transmitted to the ECM as voltage changes ( see scheme 1in (Scheme 108) ).
2. The IAT sensor is powered by a 5 V supply from the THA terminal of the ECM, via resistor R.
3. Resistor R and the IAT sensor are connected in series. When the resistance value of the IAT sensor changes, according to changes in the IAT, the voltage at terminal THA also varies. Based on this signal, the ECM increases the fuel injection volume when the engine is cold to improve driveability. HINT: When any of DTCs P0112 and P0113 is stored, the ECM enters fail-safe mode. During fail-safe mode, the IAT is estimated to be 20°C (68°F) by the ECM. Fail-safe mode continues until a pass condition is detected.

FAIL-SAFE

When any of these DTCs or other DTCs relating to ETCS (Electronic Throttle Control System) malfunctions are stored, the ECM enters fail-safe mode. During fail-safe mode, the ECM cuts the current to the throttle actuator, and the throttle valve is returned to a 7° throttle angle by the return spring. The ECM then adjusts the engine output by controlling the fuel injection (intermittent fuel cut) and ignition timing, in accordance with the accelerator pedal opening angle, to allow the vehicle to continue at a minimal speed. If the accelerator pedal is depressed firmly and gently, the vehicle can be driven slowly.

Fail-safe mode continues until a pass condition is detected, and the engine switch is then turned off.

Scheme 123

When the engine misfires, high concentrations of hydrocarbons (HC) enter the exhaust gas. Extremely high HC concentration levels can cause increases in exhaust emission levels. High concentrations of HC can also cause increases in the Three-Way Catalytic Converter (TWC) temperature, which may cause damage to the TWC. To prevent these increases in emissions and to limit the possibility of thermal damage, the ECM monitors the misfire rate. When the temperature of the TWC reaches the point of thermal degradation, the MIL blinks. To monitor misfires, the ECM uses both the Camshaft Position (CMP) sensor and the Crankshaft Position (CKP) sensor. The CMP sensor is used to identify any misfiring cylinders and the CKP sensor is used to measure variations in the crankshaft rotation speed. Misfires are counted as when the crankshaft rotation speed variations exceed predetermined thresholds.

If the misfire rate exceeds the threshold level, the ECM illuminates the MIL and stores DTC(s).

When multiple DTCs for misfiring cylinders are stored, but DTC P0300 is not stored, it indicates that misfires have been detected in different cylinders at different times. DTC P0300 is only stored when several misfiring cylinders are detected at the same time.

Note. This Secondary Air Injection Check only allows technicians to operate the AIR system for a maximum of 5 seconds. Furthermore, the check can only be performed up to 4 times per trip. If the test is repeated, intervals of at least 30 seconds are required between checks. While AIR system operation using the Techstream is prohibited, the Techstream display indicates the prohibition (WAIT or ERROR). If an ERROR is displayed on the Techstream during the test, stop the engine for 10 minutes, and then try again. Performing the Secondary Air Injection Check repeatedly may cause damage to the AIR system. If necessary, leave an interval of several minutes between System Check operations to prevent the system from overheating. When performing the Secondary Air Injection Check operation after the battery cable has been reconnected, wait for 7 minutes with the engine switch turned on (IG) or the engine running. Turn the engine switch off when the Secondary Air Injection Check operation finishes.

1. Start the engine and warm it up.
2. Turn the engine switch off.
3. Connect the Techstream to the DLC3.
4. Turn the engine switch on (IG).
5. Turn the Techstream on.
6. Clear the DTCs (if set). Refer to «DTC CHECK / CLEAR [01/2012 - ]»(ref-603920-S02560161982014031100000) .
7. Turn the engine switch off and wait for at least 30 seconds.
8. Turn the engine switch on (IG) and turn the Techstream on [A].
9. Enter the following menus: Powertrain / Engine and ECT / Utility / Secondary Air Injection Check / Automatic Mode.
10. Start the engine after the Techstream initialization is finished.
11. Perform the System Check operation by pressing ENTER (Next).
12. After operating the AIR system, perform the following to confirm the AIR system pending codes: Press the ENTER (Exit).
13. Check DTCs [B]. OK No DTC is output.
14. After the "Secondary Air Injection Check" is completed, check for All Readiness by entering the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
15. Input the DTC: P0412 or P0415.
16. Check the DTC judgment result. Tester Display Description NORMAL DTC judgment completed System normal ABNORMAL DTC judgment completed System abnormal INCOMPLETE DTC judgment not completed Perform driving pattern after confirming DTC enabling conditions N/A Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit HINT: If the judgment result shows NORMAL, the system is normal. If the judgment result shows ABNORMAL, the system has a malfunction.
17. If the test result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs. Refer to «DTC CHECK / CLEAR [01/2012 - ]»(ref-603920-S02560161982014031100000) . HINT: If no permanent DTC is output, the system is normal. If a permanent DTC is output, the system is malfunctioning.
18. Turn the engine switch off.

1. INSPECT AIR SWITCHING VALVE ASSEMBLY Disconnect the air switching valve (ASV) connector. Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition C35-5 (+B) - C35-1 (GND) 20°C (68°F) 4.5 to 5.5 ohms C36-5 (+BL) - C36-1 (GNDL) 20°C (68°F) 4.5 to 5.5 ohms NG --> See step 4 OK: Go to next step
2. CHECK HARNESS AND CONNECTOR (AIR SWITCHING VALVE - BODY GROUND) Disconnect the ASV connector. Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition C35-1 (GND) - Body ground Always Below 1 ohms C36-1 (GNDL) - Body ground Always Below 1 ohms NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK: Go to next step
3. CHECK HARNESS AND CONNECTOR (AIR SWITCHING VALVE - AIR INJECTION CONTROL DRIVER) Disconnect the ASV connector. Disconnect the AID connector.
