ON–VEHICLE INSPECTION NOTICE: ”Cold” and ”Hot” in these sentences express the temperature of the coils themselves.”Cold” is from –10C (14F) to 50C (122F) and ”Hot” is from 50C (122F) to 100C (212F). 1. INSPECT IGNITION COIL (WITH IGNITER) AND SPARK TEST (a) Confirm DTC. NOTICE: If DTC is indicated, carry out troubleshooting in accordance with the procedure on the following DTC. HINT: See page 05–16 (b) Check that the spark occurs. (1) Remove the cylinder head cover No.2. (2) Remove the ignition coils (with igniter). (3) Using a 16 mm (0.63 in) plug wrench, remove the all spark plugs. (4) Install the spark plugs to each ignition coils (with igniter), and connect the ignition coil connectors. (5) Disconnect the all injector connectors. (6) Ground the spark plugs. (7) Check if spark occurs while engine is being cranked. NOTICE: Be sure to ground the spark plug, when checking. Replace the ignition coil when it is given an impact. Do not crank the engine for more than 2 seconds. If the spark does not occur, do the test as follow. (c) Using a 16 mm (0.63 in.) plug wrench, install the spark plugs. Torque: 19 N⋅m (194 kgf⋅cm, 14 ft⋅lbf) (d) Install the ignition coil with igniter. Torque: 9.0 N⋅m (92 kgf⋅cm, 80 in.⋅lbf)

IGNITION SYSTEM (2AZ–FE) 18016–02
INSPECTION 1.
SPARK PLUG
NOTICE: Try not to clean the irridium and platinum tip. However, when the cleaning is necessary, use of spark plug cleaner is recommended. Duration should be less than 20 seconds.
(a)
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
B01301
(b)
Check the electrode gap. Electrode gap: 1.0 – 1.1 mm (0.039 – 0.043 in.) Maximum electrode gap: 1.3 mm (0.051 in.) NOTICE: This engine is fitted with irridium–tipped spark plugs. Never attempt to adjust the electrode gap. Do not scratch the irridium and platinum tip between electrode gap. P03792
