2 Is engine cranked?
NO Proceed to page ST±2 and continue to
troubleshoot.
YES
3 Does engine start?
NO Go to step 7.
YES
4 Check air filter.
PREPARATION:
Remove the air filter.
CHECK:
Visually check that the air filter is not dirty or excessive oily.
HINT:
If necessary, clean the filter with compressed air. First blow from
inside thoroughly, then blow from outside of the filter.

2 Check spark plug and spark of misfiring cylinder.
PREPARATION:
(a) Disconnect the high±tension cord from the spark plug.
(b) Remove the spark plug.
CHECK:
(a) Check the plug type.
(b) Check the electrode for carbon deposits.
(c) Check the electrode gap.
OK:
(a) Platinum±tipped spark plugs with twin ground
electrodes.
Recommended spark plug:
ND made: PK20TR11
NGK made: BKR6EKPB±11
(b) No large carbon deposit present.
Not wet with gasoline or oil.
(c) Electrode gap: 1.1 mm (0.043 in.)
PREPARATION:
(a) Install the spark plug to the high±tension code.
(b) Disconnect the injector connector.
(c) Ground the spark plug.
CHECK:
Check if spark occurs while the engine is being cracked.
NOTICE: To prevent excess fuel being injected from the in-
jectors during this test, don't crank the engine for more
than 5 ~ 10 seconds at a time.
OK:
Spark jumps across electrode gap.
NG Replace or check ignition system
(See page IG±1).

CIRCUIT DESCRIPTION
Crankshaft position sensor (NE signal) consist of a signal plate and pickup coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor generates 34
signals of every engine revolution. The ECM detects the standard crankshaft angle based on the G signals,
and the actual crankshaft angle the engine speed by the NE signals.
DTC No.DTC Detecting ConditionTrouble Area
