Need help with where to start!

I have a 07 tundra with close to 200,000 miles on it. A while back I had several lights on the dash come up;

VSC off light is flashing

4lo light flashing (4-wheel drive will not work in high or low)

ABS light constant on

Traction control light on



I have changed out the front passenger wheel speed sensor with no change to the lights.



Anyone else had these issues? Any ideas on where to start to resolve this issue/issues?

 

Go to autozone or any similar auto parts store and have them run diagnostics on your truck. There's no way we can figure out what it may be as codes should sort of guide you to where you need to go. There is a matrix out here so that you can sort of figure out what the issue may be, based on lights, but unless you're pulling your exact codes this may be a shot in the dark. Any changes will take 2 driving cycles to clear, or you can clear them via the battery disconnect, but I would highly not recommend this unless you already have codes in hand. The parts store will not clear your codes, just keep that in mind.

 

The check engine light came on one time, scanned the codes and reset. Check engine light has never came back on. Codes were;

P2419

P2402

P2401

P043f

P2419
