Hey guys. I spent the weekend doing timing belt, water pump, valve cover gaskets, cam and main seals, and rebuilt the vvti pulley on my 2000 GS300. Aside from the crank bolt I need not explain, It all went exceptionally smooth. Upon starting the car, I had a check engine light, vsc, and vsc off lights. I assumed it's because I left the battery connected for the first half of the job and unplugging connectors caused it to glitch. I disconnected the battery for an hour and started it up for 15-20 minutes to get the coolant system filled up and make sure all is well. I go for a test drive and it was fine. Gave it a WOT run into third gear no problem. I make the next turn, and I'm thrown a P0325 knock sensor bank 1 code. Also looking around, I have a steady oil leak. I can't see where it's coming from, but I'm heavily assuming the front main seal, as I used a Timken seal, not having read about people insisting Toyota only for that in particular. I also have C0246 C1223 codes.

So I'm not sure if those last two are any kind of related, but I never had dash lights before this job, and the vsc and abs have always worked fine. What do you suppose could have caused a knock code like this? It does seem to be running sluggish, but I'm not certain if the ecu is cutting timing because of the code or if it truly has a problem. Somewhere I read that low oil level will trip, and the new oil leak would seem to reflect that. It seems a little too simple to be just low oil to me, but I will check in a couple hours when it's daytime.

Any advice on the matter is greatly appreciated. Thanks.

 

Ok, so anyway.. I found this. So I guess it's a pointless thread.

 

Was that the cause of both the oil leak and code?

 

No, that's just the knock code. The oil leak is my aftermarket front seals.
