VSC light, check engine light, and trac off turned on a 65k mile LS430
hope everyone is having a good memorial weekend, well the infamous VSC light, check engine light, and trac off came on as I moved my car out of the garage. I ran the codes and it came out to P0456. Any idea what kind of problem that it could be? I'm hoping its just a replacement of a gas cap 😅 Hope those who are more experienced can point me in the right direction. Thanks all
if you disconnect your battery for a few minutes the lights will go away
there is a chance they will never come back or at least they will not come back for a long time, many miles
if and when they come back a trip to the dealer might be needed
I had this and my guys wanted to smoke check everything. I said no, just start replacing the most likely culprit hoses. They gave me 3 progressive stages and we started with level one and it hasn’t come back on in months. If it comes back we do the level 2 intervention.
