knock sensor
 

So this morning my SES light came on and I had it checked yhis afternoon, came back knock sensor bank 2. Im familiar with this issue from reading on these forums but my trucks not having any of the usual symptoms that go along with this code. Heres my delima, I have a trip planned for this weekend and I need the truck do yall think it would be safe to drive or is it just a nightmare waiting to happen? I dont really have time to fix unless I take time off work which I dont want to have to do...
