Review on Genuine Honda 30530 PPL A01 Knock Sensor by Tim Larsen

Works great. My 2005 Honda has a check engine light on. Code p0325, after a little research it turned out to be a knock sensor. I called the Honda dealer and told me $110 for it. After searching Amazon I found it for about $55 and bought it. It took me about 45 minutes to install. The check engine light no longer lights up. and my E works much better. I had to buy a 1-1/16" socket to remove and install the knock sensor. There are videos on YouTube showing the uninstall and install steps.
