DTC Detecting Condition and Trouble Area
DTC detecting condition
Voltage difference between torque sensor main signal and
sub signal is more than 0.6 V for 1 second continuously
(1 driving cycle detection logic)
DTC Troubleshooting
Step
1 Was "EPS System Check" performed?
2 DTC check
Is DTC C1114 and/or DTC C1119 indicated together?
3 Torque sensor signal (sub) circuit check
1) Check for P/S control module connector ("E52") for
proper connection.
2) With ignition switch turned OFF, disconnect torque
sensor connector.
3) Check for voltage between "E53-7" ("BLU" wire) terminal
and body ground with ignition switch ON.
Is it about 5 V?
