After searching the forum I'm seeing lots of posts on P0330 error codes but nothing on P0333 which is what my OBDII reader displays as a bank 2 knock sensor. My 2006 LC has 213K miles, I've owned it for about 1 yr and it's been 100% reliable. Over the last 2 weeks my CEL comes on along with VSC off and VSC Trac. The 3 lights (always together) have come on and off usually after driving about 50 miles or so - they're currently on.
I'm not noticing anything unusual about the vehicle, engine performance is normal, no loss of power. If those lights weren't lit on my dash I wouldn't know anything was wrong. I researched the VSC Trac and VSC off along with CEL and one potential fix is related to the fuel cap. I replaced the fuel cap with new OEM and the lights went off after driving a few miles. About 30 miles later the 3 lights are back on. Called the dealer and explained the error code - he's quoting me $194 for knock sensor, $56 for gaskets, and $1900 for a new wiring harness. I'm sure if they see the wire was chewed by rodents or somehow broken their fix is to replace the entire harness, not solder a new connection. Looking into the engine bay I'm not seeing any evidence of rodent activity.
Looking for guidance on how P0330 and P0333 error codes differ and whether the approach to diagnose is the same? Should I be looking for anything other than a knock sensor or connected wiring before dismantling engine components?
Thanks for any help or suggestions.
