Spark Check for spark at secondary coil wire and each spark plug wire using a spark tester. If spark is not present, continue with following tests. Check spark plug wire resistance on suspect wires. Resistance should be less than 25,000 ohms. Ignition Coil Power Source 1. On Civic, remove distributor cap to check power source directly at coil. On all models, disconnect ignition coil primary leads. Turn ignition on. Using voltmeter, check voltage between ground and Black/Yellow wire terminal of ignition coil harness. 2. Battery voltage should be present. If battery voltage is not present, check for open in Black/Yellow wire between coil and ignition switch. Ignitor Power Source Turn ignition off. Disconnect harness connector at distributor. Turn ignition on. Using voltmeter, check for battery voltage between ground and Black/Yellow wire of harness. If voltage is not present, check for open in Black/Yellow wire between ignition coil and harness connector. If wire is okay, check ignition coil resistance (for internal short to ground). Ignitor Check Check TDC/CRANK/CYL sensor resistance values. See TACH PULSE SIGNAL . Check power sources. If no problems are found and spark is not present, replace ignitor. Ignition Coil Resistance (Accord & Prelude) 1. Remove primary and secondary leads from ignition coil. Using an ohmmeter, check resistance between primary terminals “A” and “C” (“A” and “B” for Prelude) of ignition coil. See Fig. 2 . Resistance should be .6-.8 ohm at room temperature. 2. On Accord, check resistance between terminals “B” and “D” of ignition coil (tachometer circuit). Resistance should be about 2090-2310 ohms at room temperature. 3. On all models, check secondary resistance between terminal “A” and secondary output terminal (coil tower). See IGNITION COIL RESISTANCE table. Check for continuity between terminals “A” and “B” (“A” and “C” for Prelude). Continuity should exist. If readings are not within specification, replace coil.

Ignition Coil Test (Accord 2.3L & CR-V) 1. Turn ignition off. Remove distributor cap, rotor and leak cover. Remove primary leads from ignition coil. Using an ohmmeter, check primary resistance between ignition coil terminals “A+” and “B-”. See Fig. 12 . Resistance should be as specified. See IGNITION COIL RESISTANCE table. 2. Check secondary resistance between ignition coil terminal “A+” and secondary output terminal (ignition coil tower). See IGNITION COIL RESISTANCE table. If readings are not as specified, replace ignition coil.Ignition Control Module (ICM) Input Test (Accord 2.3L) 1. Turn ignition off. Remove distributor cap, rotor and leak cover. Disconnect wires from ICM. See Fig. 14 or Fig. 15 . Turn ignition on. Check for voltage between body ground and ICM Black/Yellow wire. If battery voltage exists, go to next step. If battery voltage does not exist, check for open in Black/Yellow wire between ignition switch and ICM. See WIRING DIAGRAMS article.

REMOVAL 1. Remove the wet cowl. 2. Disconnect the spark plug wires from the ignition coil. CAUTION: When removing the spark plug wires a slight twisting motion will break the seal and ease removal. 3. Disconnect the ignition coil electrical connector. 4. Remove the mounting screws and remove the ignition coil. INSTALLATION 1. To install, reverse the removal procedure.

rePaIr Procedure/InformatIon Step 1) Ignition Coil Inspection Check the tower portion of the ignition coil for carbon tracks (leakage). If leakage is more than 5mm long, the ignition coil and high tension cables should be replaced (see Figure 1). Figure 1 Example of leakage on ignition coil tower. Step 2) High Tension Cable Inspection Check the high tension cables for carbon tracks (leakage). If leakage is evident, the high ten- sion cables should be replaced and the ignition coil cleaned (see figure 2 and refer to Step 3). Figure 2 Leakage on cable. Step 3) Ignition Coil Cleaning Procedure (if carbon track is less than 5mm) • • • • note: Do not insert the high tension cables until the ignition coil is dry. If there is any evidence of carbon, clean the surface of the ignition coil using a clean, soft rag dampened with water. Permit the ignition coil to dry. Clean the same area of the ignition coil using a clean soft rag dampened with Isopropyl alcohol. Permit the ignition coil to dry.
