Knock Sensor and Supercharge Question
I'm new on this forum and have very limited mechanical knowledge. That said, I've got a 2003 Xterra SE with a Supercharger and just recently started getting the Check Engine Light. The past two times I've had the
P0328 Knock Sensor code shows up. I've read some of the posts here that say this will disable your supercharger. If this is correct, could this cause any other problems if I just continue to drive it without getting it fixed? From what it sounds like, its an expensive fix and I haven't noticed a loss in power since i've had the truck. (4 years).
The other codes that have popped up were the P0430 - Catalyst System Efficency Below Threshold, which let me to finding the cracked exhaust manifold. And the P0132 O2 sensor, which just came up after replacing the manifold and replacing the stock muffler with a Magnaflow. Still need to figure this one out too.
Thanks for any advice.
