Ignition Coil: Testing and Inspection
IGNITION COIL INSPECTION[L3, AJ]
L3
Ignition coil inspection
1. Perform the spark test and identity the malfunctioning cylinder.
2. Replace the ignition coil of the malfunctioning cylinder with that of a normal cylinder, and reperform the spark test.
-
If the spark is not normal due to a malfunctioning ignition coil, replace that ignition coil.
-
It is unlikely that all four ignition coils fail to operate properly. To prevent replacing a normal component, perform the above procedure,
identify the malfunctioning ignition coil, and replace it.
Ignition coil with built-in igniter inspection
1. Disconnect the ignition coil connector.
2. Measure the resistance between each terminal on the ignition coil connector using an analog circuit tester.
-
If the measurement corresponds to the table, replace the ignition coil.
AJ
Primary coil winding
1. Disconnect the ignition coil connector.
2. Measure the resistance between terminal A and B using a tester.
-
If not within the specification, replace the ignition coil.
Specification:
0.45-1.15 ohms {25 °C {77 °F)]
Secondary coil winding
1. Remove the ignition coil.
