So I just bought an IS250 SE 2007 and the guy who I bought it from told me that the car only needs 1 camshaft position sensor changed in bank 2, a simple job. Well, I swapped the sensors from bank 1 to bank 2, took out the battery and cleared the codes, but the error is still in bank 2.
Here are the results of my OBD scan:

These are the only 2 errors I have and for the life of me I can't figure it out. Googling doesn't help, all of the post are about "open circuit" which is easy, just look at all the connectors and check for loose wiring, but my error says "circuit malfunction" which is really vague... Some people say it might be the motor some say it might be the ECU, but the car drives relatively fine but it deactivated TC and the engine light is on and I need to get it fixed before my inspection.

So, does anyone have any ideas what this might be? What do I need to check?
