STEP ACTION YES NO
1 Was “SYSTEM CHECK FLOW TABLE” performed? Go to Step 2. Go to “SYSTEM
CHECK FLOW
TABLE” in this section.
2 Is DTC 14 or 16 indicated, too? Go to flow table corre-

2) Check proper connection to P/S control module.
3) If OK, turn ignition switch to ON position.
4) Hold steering wheel at position for run straight.
5) Check voltage between “X02-5” (“W” wire) termi-
nal and “X02-3” (“G” wire) terminal with “X02”
connector connected to P/S control module.
Is it about 2.5V?
Go to Step 4. Repair high resistance,
open or short to power
circuit or ground in
torque sensor main
sensor “X02-5” (“W”
wire) circuit and
recheck.
4 1) Check voltage between “X02-4” (“B” wire) termi-
nal and “X02-3” (“G” wire) terminal with “X02”
connector connected to P/S control module.
Is it about 2.5V?
Go to Step 5. Repair high resistance,
open or short to power
circuit or ground in
torque sensor sub
sensor “X02-4” (“B”
wire) circuit and
recheck.
5 1) Check torque sensor referring to “ON-VEHICLE
