Accord EX Coupe L4-2254cc 2.3L SOHC (VTEC) MFI (1998)
Ignition Coil: Testing and Inspection
1. Turn the ignition switch OFF, and remove the distributor ignition (DI) cap.
F23A1 and F23A4 2.3L SOHC VTEC
F23A5 2.3L SOHC Non-VTEC
2. Disconnect the BLK/YEL and WHT/BLK (WHT/BLU for the F23A5 engine) wires from terminals A (+) and B (-) respectively.
3. Using an ohmmeter, measure resistance between the terminals. Replace the coil if the resistance is not within specifications.
NOTE: Resistance will vary with the coil temperature; specifications are at 68 °F (20 °C).
Primary Winding Resistance
(Between the A and B terminals):
F23A1, F23A4 engines: 0.45 - 0.55 Ohm
F23A5 engine: 0.63 - 0.77 Ohm
Secondary Winding Resistance
(Between the A and Secondary Winding terminals)
F23A1, F23A4 engines: 16.8 - 25.2 k Ohm
F23A5 engine: 12.8 - 19.2 k Ohm
