- INSPECT V-RIBBED BELT See step 1
- INSPECT VALVE AND 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 perform the inspection above again. If any defects or problems are found during the inspection above, perform a lash adjuster inspection See step 2 .
- INSPECT IGNITION TIMING When using the Techstream: Warm up and stop the engine. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Enter Data List Mode on the Techstream. HINT: Refer to the Techstream operator's manual for further details. Inspect the ignition timing at idle. Ignition timing 8 to 12 degrees BTDC NOTE: Turn all the electrical systems and the A/C off. Inspect the ignition timing with the cooling fans off. Check the ignition timing with the shift lever in N. Enter the following menus: TC (TE1) / OFF. Turn the ignition switch off. Disconnect the Techstream from the DLC3. When not using the Techstream: Remove the No. 2 cylinder head cover. Refer to «REMOVAL»(ref-427476-S29493784992011101200000). Connect the tester probe of a timing light to the wire of the ignition connector for No. 1 cylinder. NOTE: Use a timing light that detects the first signal. Warm up and stop the engine. Connect the clip of the timing light to the wire harness. NOTE: Use a timing light that detects the primary signal. Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3. SST: 09843-18040 NOTE: Examine the terminal numbers before connecting them. Connecting the wrong terminals can damage the engine. Inspect the ignition timing at idle. Ignition timing 8 to 12 degrees BTDC NOTE: Turn all the electrical systems and the A/C off. Inspect the ignition timing with the cooling fans off. Check the ignition timing with the shift lever in N or P. Disconnect SST from terminals 13 (TC) and 4 (CG) of the DLC3. Turn the ignition switch off. Remove the timing light. Install the No. 2 cylinder head cover. Refer to «INSTALLATION»(ref-427476-S12428758312011101200000).
- INSPECT ENGINE IDLE SPEED Warm up and stop the engine. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Enter Data List Mode on the Techstream. HINT: Refer to the Techstream operator's manual for further details. Inspect the engine idle speed. Idle speed 600 to 700 RPM NOTE: Turn all the electrical systems and the A/C off. Inspect the idle speed with the cooling fans off. Check the idle speed with the shift lever in N or P. Turn the ignition switch off. Disconnect the Techstream from the DLC3.
- INSPECT COMPRESSION Warm up and stop the engine. Remove the No. 2 cylinder head cover. Refer to «REMOVAL»(ref-427476-S29493784992011101200000). Remove the 4 ignition coils. Remove the 4 spark plugs. Refer to «REMOVAL»(ref-427474-S42852575522011101200000). Disconnect the 4 fuel injector connectors. Inspect the cylinder compression pressure. Insert a compression gauge into the spark plug hole. Fully open the throttle. While cranking the engine, measure the compression pressure. Compression 1373 kPa (14.0 kgf/cm 2, 199 psi) Minimum pressure 1079 kPa (11.0 kgf/cm 2, 157 psi) Difference between each cylinder 98 kPa (1.0 kgf/cm 2, 14.2 psi) or less NOTE: Use a fully-charged battery so that the engine speed can be increased to 250 RPM or more. Inspect the other cylinders in the same way. Measure the compression in as a short time as possible. If the cylinder compression is low, pour a small amount of engine oil into the cylinder through the spark plug hole, then inspect it again. HINT: If adding oil increases the compression, the piston rings and/or cylinder bore may be worn or damaged. If the pressure stays low, the valve may be stuck or seated improperly, or there may be leakage from the gasket. Connect the 4 fuel injector connectors. Install the 4 spark plugs. Refer to «INSTALLATION»(ref-427474-S19289981902011101200000). Install the 4 ignition coils. Torque: 10 N*m (102 kgf*cm, 7 ft.*lbf) Install the No. 2 cylinder head cover. Refer to «INSTALLATION»(ref-427476-S12428758312011101200000).
- INSPECT CO/HC HINT: This check determines whether or not the idle CO/HC complies with local regulations. Start the engine. Run the engine at 2500 RPM for approximately 180 seconds. Insert the CO/HC meter testing probe at least 40 cm (1.3 ft.) into the tailpipe while idling. Check the CO/HC concentration during idle and when the engine is running at 2500 RPM. HINT: When doing the 2 mode (with the engine idling/ running at 2500 RPM) test, the measuring procedures are determined by applicable local regulations. If the CO/HC concentration does not comply with local regulations, troubleshoot in the order given below. Check the A/F sensor and heated oxygen sensor operation. See the table below for possible causes, then inspect the applicable parts and repair them if necessary. CO HC Problem Possible Cause Normal High Rough idle Faulty ignition: Incorrect timing Fouled, shorted or improperly gapped plugs Incorrect valve clearance Leakage from intake and exhaust valves Leakage from 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 cleaner filter element Plugged PCV valve Faulty EFI system: Faulty pressure regulator Faulty engine coolant temperature sensor Faulty mass air flow meter Faulty ECM Faulty injectors Throttle body

- INSPECT V-RIBBED BELT Check the belt for wear, cracks or other signs of damage. If any of the following defects is found, replace the V-ribbed belt. The belt is cracked. The belt is worn out to the extent that the cords are exposed. The belt has chunks missing from the ribs. Check that the belt fits properly in the ribbed grooves. HINT: Check with your hand to confirm that the belt has not slipped out of the groove on the bottom of the pulley. If it has slipped out, replace the V-ribbed belt. Install a new V-ribbed belt correctly. Check that nothing gets caught in the tensioner by turning it clockwise and counterclockwise. If a malfunction exists, replace the V-ribbed belt tensioner. Check the V-ribbed belt deflection and tension. Deflection Item Specified Condition New belt 7.0 to 8.2 mm (0.276 to 0.323 in.) Used belt 7.6 to 10.0 mm (0.299 to 0.394 in.) Tension Item Specified Condition New belt 700 to 800 N (71 to 82 kg, 157 to 180 lb) Used belt 550 to 750 N (56 to 77 kg, 124 to 169 lb) If the belt deflection is not as specified, adjust it. HINT: When inspecting the V-ribbed belt deflection, apply 98 N (10 kgf) tensile force to it. After installing a new belt, run the engine for approximately 5 minutes and then readjust the tension to (new belt) specifications. Check the V-ribbed belt deflection and tension at the specified point. V-ribbed belt tension and deflection should be checked after 2 revolutions of the engine. V-ribbed belt tension and deflection should be checked at TDC crank angle and cold condition. When adjusting a belt, adjust its deflection and tension to the intermediate values of the specification. When reinstalling a belt which has been used for over 5 minutes, adjust its deflection and tension to the used belt specification. When using a belt tension gauge, confirm its accuracy by using a master gauge first. If using a sonic tension meter: Input data for sonic tension meter Weight 15 g/rib*m Width 6 ribs Span 188 mm (7.40 in.) (w/ air conditioning) 282 mm (11.1 in.) (w/o air conditioning)
