Your Accord's engine ignition timing will be measured in degrees. An
ignition timing failure for example; your car's ignition timing is required
to be set at 15 degrees Before Top Dead Center (BTDC) and instead is set to
10 After Top Dead Center (ATDC). This fault will cause a functional failure,

standards allow timing to be up to 3 degrees +/- off the manufacturer's
required setting; resetting is recommend. One or two degrees off will not
cause your vehicle to fail the ignition timing inspection.
