1 Was “EPS System Check” performed? Go to Step 2. Go to “EPS System
Check”.
2 DTC check
Is DTC C1153 indicated together?
Go to DTC C1153 diag.
flow.
Go to Step 3.
3 Torque sensor main power supply voltage check
1) With ignition switch turned OFF, disconnect torque
sensor connector.
2) Check for P/S control module connector (“E52”) for
proper connection.
3) If connections are OK, check for voltage between “E52-
8” (“GRN” wire) terminal and body ground with ignition
switch ON.
Is it approx. 12 V?
Go to Step 4. Go to Step 5.
4 Torque sensor main power supply voltage check
1) With ignition switch turned OFF, connect torque sensor
connector.
2) Check for P/S control module connector (“E52”) for
proper connection.
3) Turn ignition switch ON.
4) Check for voltage between “Main power supply for
torque sensor circuit” terminal and body ground with
connector (“E52”) connected to the P/S control module.
Is it about 12 V?
Substitute a known-
good P/S control
module and recheck.
Replace steering gear
case assembly and
recheck.
5 Torque sensor main power supply circuit check
1) With ignition switch turned OFF, disconnect P/S control
module connector.
2) Check that “Main power supply for torque sensor circuit”
is as following.
• Insulation resistance of “Main power supply for torque
sensor circuit” wire is infinity between its terminal and
other terminal at torque sensor connector.
• Wiring resistance of “Main power supply for torque
sensor circuit” is less than 1 Ω.
• Insulation resistance of “Main power supply for torque
sensor circuit” between its circuit and vehicle body
ground is infinity.
Is circuit in good condition?
Replace P/S control
module.
Repair or replace
defective circuit.
