Hi,

Just recently got a 2006 G35x for $3500CAD with 270k km. Has a P0507 and P0462 code + vdc off, AWD, slip, ABS lights are all on. The car is running good so I think most issues are probably due to sensors. Not sure if I made the right decision for getting it in that condition. Hopefully I do not need to spend a lot to fix those issues.

Thank you for all the information I may learn here.

 

P0507 - idle control system malfunction, usually this is a vacuum leak or stuck open PCV valve or something along those lines. Rarely it can be caused by a malfunctioning throttle body, or from unplugging the throttle body and not performing the recalibration for it after you plug it back in.

P0462 - Fuel level low input, sometimes it's just worn/dirty contacts on the fuel level sensor. You can take out the fuel pump, and the sub pump, clean both sets of float arm contacts with a #2 pencil lead (scribble gently on the contacts to remove the black stripe they get in the middle, then clean the graphite off when done).

AWD/ABS/SLIP is a separate issue, those are C code errors, you will need a scanner that does ABS codes for that one but start by just checking your brake fluid level to make sure it's not low. Most often your local parts house (Napa, O'reilly, etc) will scan your car for free to find the code because they want to sell you stuff.
