P0175 Bank 2
Hello, I just changed the plugs on my 2005 Taurus SEL 3.0 24 valve DOHC. Took her for a drive and the engine light came on with code P0175, and on the dash the read out told me to check transmission. On the code reader below the P0175, it said, input turbine speed sensor A circuit malfunction. Can anybody help me out here and tell me what’s going on with the car. Thank you

P0175 code is system to lean bank two.
Possible causes are -
Fuel pressure regulator vacuum hose or diagram leak.
Leaking fuel injectors.
Fuel return line restricted.
Fuel rail pressure sensor fault.
EVAP canister purge leak.
Personally I would go over the engine bay for vacuum lines disconnected/damaged while removing the intake manifold. Also check if your MAF is damaged/corroded.
