ON- -VEHICLE INSPECTION
NOTICE:
"Cold" and "Hot" in the following sentences express the temper-
ature of the coils themselves. "Cold" is from - -10˚C (14˚F) to 50˚C
(122˚F) and "Hot" is from 50˚C (122˚F) to 100˚C (212˚F).
1. INSPECT IGNITOR AND SPARK TEST
Check that the spark occurs.
(1) Disconnect the high--tension cords from the spark
plugs.
(2) Remove the spark plugs.
(3) Install the spark plugs to each high--tension cord.
(4) Ground the spark plug.
(5) Check if spark occurs while engine is being
cranked.
NOTICE:
To prevent gasoline from being injected from injectors during
this test, crank the engine for no more than 1 - - 2 seconds at a
time.
If the spark does not occur, perform the test as follows:
Connect securely.
BAD
Replace the cord(s).
BAD
Check wiring between ignition switch
to ignition coil and igniter.
BAD
Replace the ignition coil.
BAD
Replace the camshaft position sensor.
BAD
Replace the crankshaft position sensor.
BAD
Check wiring between ECM, ignition coil
BAD
with igniter, and then try another ECM.
