P0325 Knock sensor code?
Hello new member here, I have a 96 LS400 that has a knock sensor 1 circuit bank 1 code. Had to do a repair on radiator nipple to coolant tank and all is good on repair and added coolant car is ok, but no have that CEL code I cleared it and it came back in right away. Can this be just change knock sensor? Major job? Thanks in advance

I have a pair of knock sensors if you need them, brand new. I had a similar issue, but mine turned out to be the harness, not the sensors.

UPDATE I checked for any intake leaks none, cleaned MAF and throttle body out, did seafoam directly into intake and gas tank with fresh premium gas. Drove for a while after clearing code but code came right back. So now before just throwing parts at it is there a way to check knock sensor operation while still on car? or is there a testing method to confirm a bad knock sensor don't want to do both sensors, starter and labor for same outcome. Thanks

Update, I was able to get to knock sensors without tear down and I switched knock sensor wires to each other this is what I have come up with, so on the first CEL I had P0325 after cleared code and swapped knock sensor wires then I have a P0330 code cleared code swap back and P0325 back. So I am assuming that with swapping wires getting the code corresponding with the knock sensor in bank one is setting off code so I have a bad sensor or something triggering it. So now I will go ahead and put a new knock sensor on to try that out

That thread "identify banks?" was specific to identify the banks and that was it I didn't want to get a bunch of other stuff chimed in that's all, so is that correct what I assumed for on bank Identification drivers side is bank one?, and other threads were only created to ask what was asked specifically and for instance; not be offered a part for sale, repeats of suggestions already posted, etc so Im sorry for that and I also thought as of the weekend the threads were merged

A little confused everyone points that drivers side or left side is sitting behind steering wheel is bank 1 and now I read this according to TSRM bank 1 is right side. How does the TSRM assume whats left and right in front of car looking under hood? or from drivers seat? Thanks
