It helps your vehicle perform at its best. However, it can have issues due to component complications or malfunctions. These problems can cause irregularities in the signals being sent to your PCM, which may trigger it to set trouble codes, such as code P0342.<\/p>\n\n\n\n<p>Did a P0342 code show up after using a scan tool on your vehicle?
