NOTICE:
ºColdº and ºHotº in this section mean the temperature of the coils thems\
elves.ºColdº is from ±10 C
(14 F) to 50 C (122 F) and ºHotº is from 50 C (122 F) to 100 C (212 F).
1.INSPECT IGNITION COIL (WITH IGNITER) AND SPARK TEST
(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:

INSPECTION
1. INSPECT SPARK PLUG
(a) Clean the spark plugs.
If the electrode has traces of wet carbon, clean the electrode
with a spark plug cleaner then dry it.
Air pressure: Below 588 kPa (6kg/cm
2, 85 psi)
Duration: 20 seconds or less
(b) Check the spark plug for any damage on its thread and
insulator damage.
If there is damage, replace the spark plug.
Recommended spark plug:
DENSO madeK16R±U11
NGK madeBKR5EYA11
(c) Adjust electrode gap.
Electrode gap: 1.0 to 1.1 mm (0.039 to 0.043 in.)
2. INSPECT CAMSHAFT POSITION SENSOR
(a) Using an ohmmeter, measure the resistance between the terminals.
RESISTANCE:
835 to 1,400  at cold
1,060 to 1,645 at hot
NOTICE:
ºColdº and ºHotº mean the temperature of the coils themselves.ºColdº is from ± 10
C (14
F) to 50

C (122
F) and ºHotº is from 50
C (122
F) to 100
C (212
F).
