The knock sensor is responsible for detecting engine knocking, which is a condition that occurs when the piston makes contact with the cylinder head. This can damage the engine, so the knock sensor helps to prevent it by adjusting the timing of the spark plugs. If the knock sensor is faulty, it may not be able to detect engine knocking, which could lead to engine damage and other problems that could affect the shifting process.
For example, if the engine is knocking, it may not be able to produce enough power to shift properly. Additionally, the knocking could damage the transmission, which could also prevent the engine from shifting.
Therefore, although a bad knock sensor may not directly prevent an engine from shifting, it could lead to other problems that could affect the shifting process.
