Hi-
Just bought a 2001 Discovery Land Rover with 91000 miles. Two days after buying I am getting some fault codes-P1774, P1668, and P1171.
I have tried looking them up but come up with info. from the Ford site and Audi site.
For P1774-I found Hydraulic Pressure Sensor 1 to low
P166-I found Open/Shorted EF or FDCS open IDM ground
P1171-I found Throttle Actuation Potentiometer sign 2. Range/Performance.
If these are correct can someone tell me what they mean and how important to get fixed.
Thank you.

I was only able to find the 1774 fault which state both banks running too lean.
Did you buy this truck from a dealer, if so I would go back to them and insist they correct the problem.

clear codes see what comes back,don't worry about the p1668,...the p1171 could be a vacum leak or faulty maf sensor,hit it...needs one
