8. INSPECT VALVE LASH ADJUSTER ASSEMBLY 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 preceding inspection. HINT: If any defects or problems are found during the preceding inspection, perform valve lash adjuster assembly inspection See step 2 .
9. INSPECT IGNITION TIMING Warm up and stop the engine. HINT: A warmed up engine should have an engine coolant temperature of over 80°C (176°F), an engine oil temperature of 60°C (140°F), and the engine speed should be stabilized. When using the Techstream: Check the ignition timing. Connect the Techstream to the DLC3. Start the engine and run it at idle. Turn the Techstream main switch on. Enter the following menus: Powertrain / Engine / Data List / IGN Advance. Standard ignition timing 9.5 to 24.5° BTDC at idle NOTE: Check the ignition timing with the cooling fans off. Turn off all electrical systems and the A/C. When checking the ignition timing, the transaxle should be in neutral or park. HINT: Refer to the Techstream operator's manual for further details. Check that the ignition timing advances immediately when the engine speed is increased. Enter the following menus: Powertrain / Engine / Active Test / Connect the TC and TE1 / ON. Monitor IGN Advance. Perform the Active Test. Standard ignition timing 8 to 12° BTDC at idle NOTE: When checking the ignition timing, the transaxle should be in neutral or park. HINT: Refer to the Techstream operator's manual for further details. When not using the Techstream: Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3. TEXT IN ILLUSTRATION *1 DLC3 SST: 09843-18040 NOTE: Confirm the terminals before connecting them. Connecting the wrong terminals may result in damage to electrical components. Check the ignition timing with the cooling fans off. Turn off all the electrical systems and the A/C. When checking the ignition timing, the transaxle should be in neutral or park. Remove the V-bank cover sub-assembly. Refer to «REMOVAL [06/2012 - ]»(ref-598588-S14211297422014021400000) . Connect the timing light tester probe to the ignition coil wire for No. 1 cylinder. NOTE: Use a timing light that detects primary signals. Check the ignition timing at idle. Standard ignition timing 8 to 12° BTDC at idle NOTE: When checking the ignition timing, the transaxle should be in neutral or park. 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. Standard ignition timing 9.5 to 24.5° BTDC at idle Confirm that the ignition timing advances immediately when the engine rpm is increased. Remove the timing light from the engine. Install the V-bank cover sub-assembly. Refer to «INSTALLATION [06/2012 - ]»(ref-598588-S36474242852014021400000) .
10. INSPECT ENGINE IDLE SPEED Warm up and stop the engine. HINT: A warmed up engine should have an engine coolant temperature of over 80°C (176°F), an engine oil temperature of 60°C (140°F), and the engine speed should be stabilized. When using the Techstream: Connect the Techstream to the DLC3. Start the engine and run it at idle. Turn the Techstream main switch on. Enter the following menus: Powertrain / Engine / Data List / Engine Speed. Read the value displayed on the tester. Standard idle speed 600 to 700 rpm NOTE: Check the idle speed with the cooling fans off. Turn off all the electrical systems and the A/C. When checking the idle speed, the transaxle should be in neutral or park. HINT: Refer to the Techstream operator's manual for further details. When not using the Techstream: Using SST, connect a tachometer probe to terminal 9 (TAC) of the DLC3. TEXT IN ILLUSTRATION *1 DLC3 SST: 09843-18030 Check the idle speed. Standard idle speed 600 to 700 rpm NOTE: Check the idle speed with the cooling fans off. Turn off all the electrical systems and the A/C. When checking the idle speed, the transaxle should be in neutral or park.
11. INSPECT COMPRESSION Warm up and stop the engine. HINT: A warmed up engine should have an engine coolant temperature of over 80°C (176°F), an engine oil temperature of 60°C (140°F), and the engine speed should be stabilized. Remove the 6 spark plugs. Refer to «REMOVAL [06/2012 - ]»(ref-598604-S14733561992014021400000) . Check the cylinder compression pressure. Insert a compression gauge into the spark plug hole. While cranking the engine, measure the compression pressure. Standard compression pressure 1300 kPa (13.3 kgf/cm 2 , 189 psi) Minimum pressure 1000 kPa (10.2 kgf/cm 2 , 145 psi) NOTE: Always use a fully charged battery to obtain an engine speed of 250 rpm or more. Check the compression pressure of the other cylinders 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 the pressure stays low, a valve may be stuck or seated improperly, or there may be leakage in the cylinder head gasket. Install the 6 spark plugs. Refer to «INSTALLATION [06/2012 - ]»(ref-598604-S02645276232014021400000) .
12. INSPECT CO/HC HINT: This check determines whether or not the idle CO/HC complies with regulations. Start the engine. Keep the engine speed at 2500 rpm for approximately 180 seconds. Insert the CO/HC meter testing probe at least 40 cm (1.31 ft.) into the tailpipe during idle. Immediately check CO/HC concentration during idle and when running at 2500 rpm. HINT: When performing the 2 mode (with the engine idling/running at 2500 rpm) test, follow the measurement order determined by applicable local regulations. If the CO/HC concentration does not comply with the regulations, perform troubleshooting in the order given below. Check the DTCs. Refer to «DTC CHECK / CLEAR [06/2012 - ]»(ref-598472-S02009234142014021400000) . Refer to the table below for possible causes, then inspect and correct the applicable causes if necessary. CO HC Problem Cause Normal High Rough idle Faulty ignition: Incorrect valve timing Fouled, shorted or improperly gapped spark plugs Incorrect valve clearance (valve lash adjuster assembly) Leaks in intake or exhaust valves Leaks in cylinders Low High Rough idle (Fluctuating HC reading) Vacuum leaks: PCV hoses Intake manifold Throttle with motor body assembly Brake booster line Lean mixture causing misfire High High Rough idle (Black smoke from exhaust) Restricted air cleaner filter element sub-assembly Plugged PCV valve Faulty SFI system: Faulty fuel pressure regulator assembly Defective engine coolant temperature sensor Defective mass air flow meter sub-assembly Faulty ECM Faulty fuel injector assemblies Faulty throttle position sensor (built in throttle with motor body assembly)
