04 G35 Sedan Codes

So I met this guy to buy his 2004 g35 sedan, but it had a “service engine soon” light that went on and off throughout the day, so we scanned it. These are the codes that popped up (in the picture). He then ordered a new wire harness to fix the issue. I’m curious as to how common these codes are, what the fix may be, and how big of a deal they are? Thank you for any help!

The knock sensor code is almost always the sub harness, some folks have managed to change it out without disassembling the intake but the normal process is to remove the upper/lower plenums and the collecter intake at the bottom. Then swap the sub-harness (since you have it all apart you should just replace the entire sensor as well since it's a $20 part that probably has 100k+ miles on it). Then reassemble, it's not HARD to replace but it's a lot of little bolts and you need to follow the FSM for proper torque and pattern. If you aren't the type to actually follow the manual or torque fasteners I would opt for the other method because you will probably just screw something up.

The lean bank 1 code however could be a number of different things ranging from failed O2 sensor to failed fuel dampers to bad spark plugs to intake leaks, etc. Expect quite a bit of troubleshooting to find the actual issue.

I would consider a vehicle like that to be sold as a "mechanics special" and have a cost reduced by -30% due to the amount of labor needed to fix the problem.

If you know how to troubleshoot engine problems like this and will do the work yourself it's not a problem, if you don't know how or will be paying a shop to do the work then just walk away now because it will easily be $1k to fix those problems.
