MWBV6

Carrying on my thread in here if i can as this is really the correct place for it. Bought a v6 4motion. Went to drive it for really the first proper time on friday and it shut down Eventually got a friend to plug his diagnostic kit into it and it came back with the following codes: P1579 P1564 P1543 P1172 All these point to the throttle motor or sensor. Got hold of a relay diagram earlier, would it be worth swapping the relays to see if this is the cause? Or does it go deeper???
