Error codes c1511 and c1512 -symptom no power steering. (Torque sensor 1 & 2 respectively )
lexus told me that there was no communication through the car to the ps and they provided me with the above codes. Said this was a major job done from the inside of the car and the power steering rack would have to come out to see if it was a wiring fault or something else. This was all as a result of crossed battery terminals when jumpstarting. I had replaced the fusable link which blew, the 150a fuse blew but not the 80a ps fuse, plus the 4 x 20a door fuses and 2 x 10a audio display fuse + a 30a audio fuse as well.
A search of the internet returned the following:-
DIAGNOSIS CODE SET CONDITIONS
These diagnosis codes are set in the following cases:
C1511: Torque sensor main system malfunction
