INSPECT IGNITION COIL (WITH IGNITER) AND SPARK TEST Check that the spark occurs. (1) Remove the ignition coils (with igniter). (see page IG-5 ) (2) Remove the spark plugs. (3) Install the spark plugs to each ignition coil (with ig- niter), and connect the ignition coil (with igniter) con- nector. (4) Disconnect the 8 injector connectors. (5) Ground the spark plug. (6) Check that spark occurs while engine is being cranked. NOTICE: To prevent gasoline from being injected out of injectors during this test, crank the engine for no more than 5 to 10 seconds at a time. Author: Date: 3764 IG-2 IGNITION (2UZ-FE) - IGNITION SYSTEM If the spark does not occur, do the test as follows: SPARK TEST NG CHECK TDC NG CHECK CONNECTION OF IGNITION COIL Connect securely. CONNECTOR BAD OK CHANGE IT TO NORMAL IGNITION COIL (WITH Replace the ignition coil (with igniter). IGNITER) AND PERFORM SPARK TEST AGAIN OK NO CHECK POWER SUPPLY TO IGNITION COIL (WITH Check wiring between ignition switch IGNITER) to ignition coil (with igniter). 1. Turn ignition switch to ON. BAD 2. Check that there is battery voltage at ignition coil positive (+) terminal. OK CHECK RESISTANCE OF CRANKSHAFT POSITION Replace the crankshaft position sensor. SENSOR (See page IG-12 ) Cold Hot Resistance: 985 - 1,600 Ω 1,265 - 1,890 Ω BAD OK CHECK IGT SIGNAL FROM ECM (See page DI-642 ) BAD Check ECM (See page IN-30 ) OK REPAIR WIRING BETWEEN IGNITION COIL AND ECM (7) Using a 16 mm plug wrench, install the spark plugs. Torque: 17.5 N·m (180 kgf·cm, 13 ft·lbf) (8) Reinstall the ignition coils (with igniter). (see page IG-6 ) 2. INSPECT SPARK PLUGS (a) Remove the ignition coils (with igniter). (see page IG-5 ) (b) Using a 16 mm plug wrench, remove the spark plugs. 16 mm Plug Wrench B03198 Author: Date: 3765 IG-3 IGNITION (2UZ-FE) - IGNITION SYSTEM (c) Clean the spark plugs. If the electrode has traces of wet carbon, allow it to dry and then clean with a spark plug cleaner. Air pressure: Below 588 kPa (6 kgf/cm2, 85 psi) Duration: 20 seconds or less HINT: If there are traces of oil, remove it with gasoline before using the spark plug cleaner. IG0152 (d) Check the spark plug for thread damage and insulator damage. If abnormal, replace the spark plug. Recommended spark plug: DENSO made SK20R11 NGK made IFR6A11 IG0148 (e) Adjust the spark plug electrode gap. Electrode gap: 1.0 to 1.1 mm (0.039 to 0.043 in.) (f) Using a 16 mm plug wrench, install the spark plugs. Torque: 17.5 N·m (180 kgf·cm, 13 ft·lbf) (g) Reinstall the ignition coils (with igniter). (see page IG-6 ) P03792 Author: Date: 3766.
