Your Toyota knock sensor is an important part of seeing to it that your combustion system functions as it should. As its name indicates, your Toyota knock sensor detects the vibration that engine knocking and pinging can cause. The knocking and pinging is typically related to improper combustion, taking place outside of the correct location or just a touch too early and, if allowed to continue, could result in expensive damage to the sensitive inner parts of the combustion chamber, such as within the pistons. When the Toyota knock sensor picks up the vibration of the pinging and knocking, it signals the vehicle's computer, which, in turn, makes adjustments to the combustion process and timing. When your Toyota knock sensor malfunctions or fails, the computer of your vehicle is not going to get the reliable information that it needs to see to it that the process of combustion is as balanced as it needs to be for your vehicle to perform as well and efficiently as it should.
