Measure secondary resistance after removing a ignition coil. (Secondary resistance is measured between (+) terminals and center terminals.)
A.
Specification :
Primary Coil resistance : 0.62 ± 10% Ω
Secondary Coil resistance : 7.0 ± 15% kΩ
The purpose of the Inspection is to analyze the cause of hesitation through ignition coil inspection.
IG "OFF"
Measure the primary resistance after removing ignition coil connectors. (Primary resistance is measured between (+) terminals and (-) terminals.)
Measure secondary resistance after removing a ignition coil. (Secondary resistance is measured between (+) terminals and center terminals.)
Specification :
Primary Coil resistance : 0.62 ± 10% Ω
Secondary Coil resistance : 7.0 ± 15% kΩ
Is the primary resistance of the ignition coil normal?
YES
Ignition coil is OK.
NO
Replace the ignition coil.
