What's the DTC code Andrew ?

[Timothy Goggin]

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

• The torque sensor main output voltage does not agree with the predetermined voltage stored in the microcomputer, and the microcomputer determines that a problem has occurred in the torque sensor main system.

C1512: Torque sensor sub system malfunction

• The torque sensor sub output voltage does not agree with the predetermined voltage stored in the microcomputer, and the microcomputer determines that a problem has occurred in the torque sensor sub system.
