How to Troubleshoot the Ignition System in a Honda Accord. You should only troubleshoot your Accord's ignition system if you have an older model with a distributor-based system. The distributorless system on newer models is too complex for anyone but an expert to look over. For a distributor system, you will mainly check the igniter and the ignition coil resistance.

Igniter Check

Remove the Accord's distributor cap, rotor and inner cover. Disconnect the wires from the igniter.

Use a voltmeter to check for voltage between the black/yellow wire and the ground. Battery voltage should be present when you turn the ignition to "On." Check the black/yellow wire between the ignition switch and igniter if no voltage is present.

Check for voltage between the green wire and ground with the ignition switch on. Check the ignition coil and the green wire between the coil and igniter if there is no voltage.

Turn the ignition switch off. Check the yellow/green wire for continuity between the engine control module and igniter. Do the same for the BLU 1 wire between the tachometer and igniter.

Replace the igniter if all the wiring checks out and a problem still exists.

Ignition Coil Test on a VTEC Engine

Turn the Accord's ignition off and remove the distributor cap. Remove the screws holding the black/yellow wire (connecting the primary positive terminal) and blue wire (connecting the primary negative terminal).

Test the resistance between the primary positive and negative terminals with an ohmmeter. It should be between 0.4 and 0.6 ohms.

Observe the resistance between the primary positive terminal and the secondary terminal. It should be 22,000 to 34,000 ohms.

Replace the coil if any of the tests fail.

Ignition Coil Test on Other Engines

Unplug the primary and secondary wiring connectors from the Accord's ignition coil while the ignition is off.

Connect an ohmmeter to terminals A and B on the primary connector (A and C on a V-6 engine). The resistance should be between 0.6 and 0.8 ohms.

Measure the resistance with the ohmmeter between terminal A and the secondary terminal. It should be between 14,000 and 22,000 ohms.

Test at terminals A and C (A and B on a V-6 engine). Make sure there is continuity.

Replace the coil if any of the conditions aren't met.


If the Accord has a V-6 engine, there is no BLU 1 wire to check. If your Honda engine has VTEC, the green wire is a BLU 2 wire.
