Engine code on E250
2001 Econoline V6 4.2
I got these codes but am having trouble finding the definition as to the cause.
P1270 Engine RPM Vehicle speed limiter reached
P0174 Systen too lean (Bank 2)
P1151 Ho2S Bank 2 Sen 1 in Suff switching lean mean.
How can I find out what parts I need or any other info tohelp me fix it?
Thanks

Welcome to the forum 
The second two can be caused by a dirty MAF or a bad PCV hose elbow. Shes running too lean.
The first code means that the engine has turned enough rpm to reach the rev limiter.

Thanks for the reply. Yes, she has turned alot of rpm's. 200 k miles on it.
Is this a fixable code or do I just clear it out after I solve the other 2 codes?
Its a work van that I want to run till it drops.
Thanks
