Power Assisted Steering System: 6C-23
DTC Troubleshooting
Step Action Yes No
1 Was “EPS System Check” performed? Go to Step 2. Go to “EPS System
Check”.
2 DTC check
Is DTC C1113, C1114 and/or DTC C1119 indicated together?
Go to applicable diag.
flow.
Go to Step 3.
3 Torque sensor internal failure signal voltage check
1) Check for P/S control module connector (“E52”) for
proper connection.
2) Check for voltage between “E52-16” (“YEL” wire)
terminal and body ground with ignition switch ON.
Is voltage 0 – 1 V?
Substitute a known-
good P/S control
module and recheck.
Go to Step 4.
4 Torque sensor internal failure signal circuit check
1) With ignition switch turned OFF, disconnect torque
sensor connector.
2) Check for voltage between “E53-1” (“YEL” wire) terminal
and body ground with ignition switch ON.
Is it about 5 V?
Go to Step 5. Go to Step 6.
5 Torque sensor internal failure signal circuit check
1) Disconnect P/S control module connector.
2) Check that torque sensor failure signal circuit is as
follows.
• Insulation resistance of wire harness is infinity
between “Torque sensor internal failure signal circuit”
terminal and other terminal at torque sensor
connector.
Is circuit in good condition?
Go to Step 7. Repair or replace
defective circuit.
6 Torque sensor internal failure signal circuit check
1) Disconnect P/S control module connector.
2) Check that torque sensor failure signal circuit is as
follows.
• Insulation resistance of wire harness is infinity
between “Torque sensor internal failure signal circuit”
terminal and other terminal at torque sensor
connector.
• Wiring harness resistance of “Torque sensor internal
failure signal circuit” is less than 1 Ω.
Is circuit in good condition?
Substitute a known-
good P/S control
module and recheck.
Repair or replace
defective circuit.
7 Torque sensor signal circuit check
1) Check for torque sensor signal circuit referring to Step 3)
– 8) of “DTC C1113: Steering Torque Sensor (Main and
Sub) Circuit Correlation”.
Is torque sensor and its circuit in good condition?
Replace steering gear
case.
Repair or replace
defective parts.
