Scheme 4

1. INSPECT VALVE LASH ADJUSTER NOISE Rev up the engine several times. Check that the engine does not emit unusual noises. If unusual noises occur, warm up the engine and idle it for over 30 minutes. Then repeat this procedure. HINT: If any defects or problems are found during the inspection above, perform lash adjuster inspection (See «INSPECTION»(ref-291113-S22690931132008072400000) ).
2. INSPECT IGNITION TIMING Warm up the engine. When using the Techstream: Check the ignition timing. Connect the Techstream to the DLC3. Enter DATA LIST MODE with the Techstream. Ignition timing: 8 to 12° BTDC at idle HINT: Refer to the Techstream operator's manual for help on selecting the DATA LIST. When not using the Techstream: Check the ignition timing. Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3. SST 09843-18040 NOTE: Confirm the terminal numbers before connecting them. Connection with a wrong terminal can damage the engine. Turn off all electrical systems before connecting the terminals. Perform this inspection after the cooling fan motor is turned off. Remove the V-bank cover. Pull out the red lead wire harness. Connect the tester terminal of the timing light to the red lead wire as shown in the illustration. NOTE: Use a timing light which detects the first signal. Check the ignition timing at idle. Ignition timing: 8 to 12° BTDC at idle NOTE: When checking the ignition timing, the transmission should be in the neutral position. HINT: Run the engine at 1000 to 1300 rpm for 5 seconds, and then check that the engine rpm returns to idle speed. Disconnect terminals 13 (TC) and 4 (CG) of the DLC3. Check the ignition timing at idle. Ignition timing: 5 to 15 BTDC at idle Confirm that the ignition timing moves to the advanced angle side when the engine rpm is increased. Remove the timing light.
3. INSPECT ENGINE IDLE SPEED Warm up the engine. When using the Techstream: Check the idle speed. Connect the Techstream to the DLC3. Enter DATA LIST MODE with the Techstream. Idle speed: 600 to 700 rpm NOTE: When checking the idle speed, the transmission should be in the neutral position. Check the idle speed with the cooling fan off. Switch off all accessories and air conditioning before connecting the Techstream. HINT: Refer to the Techstream operator's manual for further details. When not using the Techstream: Check the idle speed. Using SST, connect tachometer test probe to terminal 9 (TAC) of the DLC3. SST 09843-18030 Check the idle speed. Idle speed: 600 to 700 rpm
4. INSPECT COMPRESSION Warm up and stop the engine. Disconnect the injector connectors. Remove the intake air surge tank (See «REMOVAL»(/toyota/avalon/xx30-2007-2010/remont/fuel-system/#fuel-system-2gr-fe) ). Remove the 6 ignition coils. Remove the 6 spark plugs. Check the cylinder compression pressure. Insert a compression gauge into the spark plug hole. While cranking the engine, measure the compression pressure. Compression pressure: 1.4 MPa (14 kgf/cm 2 , 199 psi) Minimum pressure: 0.98 MPa (10 kgf/cm 2 , 142 psi) Difference between each cylinder: 0.1 MPa (1.0 kgf/cm 2 , 15 psi) NOTE: Always use a fully charged battery to obtain an engine speed of 250 rpm or more. Check the other cylinders' compression pressure in the same way. This measurement must be done as quickly as possible. If the cylinder compression is low, pour a small amount of engine oil into the cylinder through the spark plug hole and inspect again. HINT: If adding oil increases the compression, the piston rings and / or cylinder bore may be worn or damaged. If pressure stays low, a valve may be stuck or seated improperly, or there may be leakage in the gasket.
5. INSPECT CO/HC Start the engine. Rev the engine at 2500 rpm for approximately 180 seconds. Insert CO/HC meter testing probe at least 40 cm (1.3 ft) into the tailpipe during idling. Check CO/HC concentration at idle and / or 2500 rpm. HINT: Check regulations and restrictions in your area when performing 2 mode CO/CH concentration testing (engine check at both idle speed and at 2500 rpm). If the CO/HC concentration does not comply with regulations, troubleshoot in the order given below. Check A/F sensor and heated oxygen sensor operation. See the table below for possible causes, and then inspect and repair. POSSIBLE CAUSES CO HC Problems Causes Normal High Rough idle Faulty ignitions: Incorrect timing Fouled, shorted or improperly gapped plugs Incorrect valve clearance Leaks in intake and exhaust valves Leaks in cylinders Low High Rough idle (fluctuating HC reading) Vacuum leaks: PCV hoses Intake manifold Throttle body Brake booster line Lean mixture causing misfire High High Rough idle (black smoke from exhaust) Restricted air filter Plugged PCV valve Faulty SFI system: Faulty fuel pressure regulator Defective ECT sensor Defective MAF meter Faulty ECM Faulty injectors Faulty throttle position sensor

4. REMOVE V-RIBBED BELT Using SST, release the belt tension by turning the belt tensioner counterclockwise, and remove the V-ribbed belt from the belt tensioner. SST 09961-00950 While turning the belt tensioner counterclockwise, align with its holes, and then insert the 5 mm bi-hexagon wrench into the holes to fix the V-ribbed belt tensioner.

Scheme 9

1. INSPECT V-RIBBED BELT Visually check the V-ribbed belt for excessive wear, frayed cords, etc. If any defect has been found, replace the V-ribbed belt. HINT: Cracks on the rib side of a V-ribbed belt are considered acceptable. If the drive belt has chunks missing from its ribs, it should be replaced. HINT: After installing the V-ribbed belt, check that it fits properly in the ribbed grooves. Check to confirm that the belt has not slipped out of the grooves on the bottom of the crank pulley by hand. A "new belt" is a belt which has been used for less than 5 minutes with the engine running. A "used belt" is a belt which has been used for 5 minutes or more with the engine running. After installing a new belt, run the engine for approximately 5 minutes and then recheck the tension.
2. INSPECT V-RIBBED BELT TENSIONER ASSEMBLY Check that nothing gets caught in the tensioner by turning it clockwise and counterclockwise. If a malfunction exists, replace the tensioner.

Scheme 10

1. INSTALL V-RIBBED BELT Install the V-ribbed belt. Using SST, turn the belt tensioner counterclockwise, remove the bar. SST 09961-00950 If it is difficult to install the V-ribbed belt, perform the following procedure. Put the V-ribbed belt on everything except the tensioner pulley as shown in the illustration. While releasing the belt tension by turning the belt tensioner counterclockwise, put the V-ribbed belt on the tensioner pulley. NOTE: Put the backside of the V-ribbed belt on the tensioner pulley and idler pulley. Check that the V-ribbed belt is properly set to each pulley.
