A waste spark is being tested, what will not affect this system if faulty?

In a waste spark ignition system, two spark plugs fire simultaneously: one in a cylinder that is on the compression stroke and the other in a cylinder that is on the exhaust stroke. This design uses the waste spark generated during the ignition process to improve efficiency and reduce parts in the ignition system.

The ignition module is essential for controlling the timing of the spark and ensuring that the correct signals are sent to the ignition coils for firing. If the ignition module is faulty, it can lead to misfires, erratic spark timing, or complete ignition failure, significantly affecting engine performance.

The crankshaft sensor monitors the position and speed of the crankshaft, providing critical input to the ignition system. A malfunctioning crankshaft sensor can disrupt the timing of the spark event, leading to misfires and poor engine performance.

In contrast, the camshaft sensor's role is related to monitoring the position of the camshaft, which is primarily involved in determining valve timing rather than directly influencing the firing of spark plugs in a waste spark system. While a camshaft sensor issue could affect overall engine operation, its failure would not directly impact the functionality of the waste spark ignition process itself, especially since two plugs fire at the same time regardless of camshaft position.

Therefore, the cam
