19 CHANGE NORMAL SPARK PLUG AND CHECK SPARK OF MISFIRING CYLINDER
(a) Change for a normal spark plug.
(b) Perform a spark test.
CAUTION:
Absolutely disconnect the each injector connector.
NOTICE:
Do not crank the engine for more than 2 seconds.
(1 ) Install the spark plug to the ignition coil, and connect the ignition coil connector.
(2) Disconnect the injector connectors.
(3) Ground the spark plug.
(4) Check if spark occurs while the engine is being cranked.
Standard: Spark jumps across electrode gap.

(a) Turn the ignition switch to ON.
(b) Measure the voltage between the terminals of the E12
and E13 ECM connectors.
