(a)Check for DTCs.
NOTICE:
If DTC is present, perform a troubleshooting in accordance with a proced\
ure for that DTC.
(b)Check that spark occurs. (1)Remove the cylinder head cover No. 2. (See page 14±6)
(2) Remove the ignition coils (with igniter).
(3) Using a 16mm (0.63 in) plug wrench, remove the spark plugs.
(4) Install the spark plugs to each ignition coil (with igniter) and connect the \
ignition coil connectors.
(5) Disconnect the 4 injector connectors.
(6) Ground the spark plugs.
(7) Check if spark occurs at each spark plug while engine is being cranked.
NOTICE:

Be sure to ground the spark plug when checking.

Replace the ignition coil it is given physical impact.

Do not crank the engine for more than 2 seconds.
If the sparks do not occur, do the following test:

ing light comes on.
6. INSPECT ENGINE COOLANT TEMPERATURE RECEIVER GAUGE WARNING LIGHT
(a) Inspect the circuit.
(1) Disconnect the connector from the sender gauge.
(2) Turn the ignition switch to ON, check the position of the water temperature receiver gauge
needle.
Needle position: COOL
