B --> GO TO DTC CHART A: Go to next step
PERFORM ACTIVE TEST USING TECHSTREAM (OPERATE OIL CONTROL VALVE FOR EXHAUST CAMSHAFT) Connect Techstream to the DLC3. Start the engine and turn the tester on. Warm up the engine. Select the following menu items: Powertrain / Engine and ECT / Active Test / Control the VVT Exhaust Linear (Bank 1) or Control the VVT Exhaust Linear (Bank 2). Check the engine speed while operating the oil control valve using the tester. OK Tester Operation Specified Condition OCV OFF (-128%) Normal engine idle speed OCV ON (127%) Engine idles roughly or stalls (soon after OCV switched from OFF to ON) NG --> See step 4 OK: Go to next step
CHECK WHETHER DTC OUTPUT RECURS (DTC P0017 OR P0019) Connect Techstream to the DLC3. Turn the engine switch on (IG) and turn the tester on. Clear the DTCs. Refer to «DTC CHECK / CLEAR»(ref-387359-S19593904092011022400000) . Start the engine and warm it up. Switch the check mode using the tester. Refer to «CHECK MODE PROCEDURE»(ref-387359-S23762167392011022400000) . Drive the vehicle for more than 10 minutes. Read the DTCs using the tester. OK No DTC output. NG --> See step 4 OK --> END
CHECK VALVE TIMING (CHECK FOR LOOSE AND JUMP TEETH ON TIMING CHAIN) Remove the cylinder head covers RH and LH. Turn the crankshaft to align the matchmarks of the crankshaft. Align the notch of the crankshaft pulley to the "0" position. Check if the matchmarks of the camshaft pulley and camshaft bearing cap align. Turn the crankshaft clockwise by 360° if the matchmarks do not align. Check if they align once again. OK The matchmarks of the camshaft pulley and the camshaft bearing cap align when the notch of the crankshaft pulley is in the "0" position. Reinstall the cylinder head cover RH and LH. NG --> ADJUST VALVE TIMING OK: Go to next step

Scheme 289

Scheme 289: DESCRIPTION

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 (Scheme 289)
The IAT sensor is powered by a 5 V supply from the THA terminal of the ECM, via resistor R.
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 P0110, P0112 and P0113 are set, 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, as well as other DTCs relating to ETCS (Electronic Throttle Control System) malfunctions, are set, the ECM enters fail-safe mode. During the ECM cuts the current to the throttle actuator off, and the throttle valve is returned to a 6° 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.

Refer to CHECKING MONITOR STATUS. Refer to CHECKING MONITOR STATUS .

Connect Techstream to the DLC3.
Turn the engine switch on (IG).
Turn the tester on.
Record the DTC(s) and freeze frame data.
Using the tester, switch the ECM from normal mode to check mode. Refer to «CHECK MODE PROCEDURE»(ref-387359-S23762167392011022400000) .
Read the misfire counts of each cylinder (Cylinder #1 Misfire Count to Cylinder #6 Misfire Count) with the engine in an idling condition. If any misfire count is displayed, skip the following confirmation driving pattern.
Drive the vehicle several times with the conditions, such as engine RPM and engine load, shown in, Misfire RPM and Misfire Load in the Data List. HINT: In order to store misfire DTCs, it is necessary to operate the vehicle for the period of time shown in the table below, using the Misfire RPM and Misfire Load in the Data List. Engine RPM Duration Idling 3.5 minutes or more 1000 3 minutes or more 2000 1.5 minutes or more 3000 1 minute or more
Check whether misfires have occurred by checking DTCs and freeze frame data. HINT: Do not turn the engine switch off until the stored DTC(s) and freeze frame data have been recorded. When the ECM returns to normal mode (default), the stored DTC(s), freeze frame data and other data will be erased.
Record the DTC(s), freeze frame data and misfire counts.
Turn the engine switch off and wait for at least 5 seconds.
