Ignition Coil Test - Acura 3.5 RL Manual

Ignition Coil Test

1. Turn the ignition switch OFF.
2. Remove the strut brace, then remove the engine
cover (see section 5).
3. Remove the ignition coil.
4. Using an ohmmeter, measure resistance between
the terminals. Replace the coil if the resistance is
not within specification.
NOTE: Resistance will vary with the coil tempera-
ture; specification is at 77°F (25°C).
Primary Winding Resistance
(between the No. 1 and No. 2 terminals)
0.9- 1.1 ohms
If the resistance is not within specification,
replace the coil.
If the resistance is OK, but other troubleshooting
doesn't reveal the cause of the problem, substi-
tute a known-good ignition coil and check engine
operation again.
If the engine then runs OK, replace the original
coil.
