It is also powered by the battery.<\/p>\n\n\n\n<p>The primary and secondary circuits control the ignition coil. If either of them fail, they can prevent the spark plug from igniting the air-fuel mixture. Depending on which circuit failed, it could cause problems like reducing or eliminating the secondary voltage output, weakening the spark, or damage the PCM.<\/p>\n\n\n\n<p>The PCM regularly checks the ignition coil.
