Fuel injection
9 - 72
Check the resistance of the secondary
Measure the resistance between one of the two
terminals of the primary and the spark plug cable outlet.
Primary-HV cable outlet = 3.1KΩ ± 9%
NONO
NO
Replace the coil.
YES
The coil conforms.
Shielded cap control
Measure the resistance of the shielded cap
Resistance = 5 KΩ
If substantially different values are obtained (<1; >20KΩ),
proceed with replacement.
NOTE
The lack of shielding on the cap or spark plug may lead
to problems in the fuel injection system.
For full information concerning the spark plug, see the
chapter "Maintenance" Chapter. 1 - GENERAL INFOR-
MATION AND MAINTENANCE.
IGNITION TIMING
The spark advance is determined electronically on the
basis of known parameters from the control unit.
For this reason it is not possible to state reference
values based on the number of engine revolutions.
