Buick P1365 Code Description
The Buick P1365 code indicates a problem with ignition control cylinder 5 not toggling after being activated. This means the ignition system is not functioning properly for cylinder 5, which can lead to misfires, rough idling, and overall decreased engine performance. The ignition control module plays a crucial role in providing spark to the spark plugs at the right time to ignite the air-fuel mixture in the combustion chamber. When cylinder 5 does not toggle after activation, it can disrupt the timing of spark delivery, resulting in misfires and inefficient combustion.
