DTC 27-12, 27-13

DTC 27-12  : Steering Angle Sensor Stuck

DTC 27-13  : Steering Angle Sensor Output Signal Malfunction

NOTE: 

• This DTC may set if the vehicle is driven on a lift (wheels are turning) and the steering wheel is turned significantly. This is normal, ignore it.
• Before you troubleshoot, review the general troubleshooting information .

DTCs (VSA)

1. Steering angle sensor performance check 1

   -1. Slowly drive the vehicle in a straight line for 10 ft (3 m) or more, then come to a stop while maintaining the steering wheel in the straight ahead position.

   -2. Check the parameter(s) below with the HDS.

   Signal	Current conditions
   	Values	Unit
   STEERING ANGLE (CAN)

   With the steering wheel in the straight ahead position, is the value within 0+/-5 degrees?

   YES 

   Go to step 3.

   NO 

   Check the installation of the steering angle sensor . If installation is OK, go to step 2.

2. VSA sensor neutral position memorization

   -1. Clear the DTC with the HDS.

   -2. Do the VSA sensor neutral position memorization .

   -3. Turn the vehicle to the OFF (LOCK) mode.

   -4. Test-drive the vehicle at 9 mph (15 km/h) or more.

   NOTE:  Drive the vehicle on the road, not on a lift.

   -5. Check for DTCs with the HDS.

   Signal	Current conditions
   	Values	Unit
   STEERING ANGLE (CAN)

   When the steering wheel is slowly turned, does the value change?

   YES 

   Go to step 4.

   NO 

   Replace the steering angle sensor .

4. Steering angle sensor performance check 3

   -1. Set the front wheels to the straight ahead position.

   -2. Check the parameter(s) below with the HDS while turning the steering wheel one turn to the right.

   Signal	Current conditions
   	Values	Unit
   STEERING ANGLE (CAN)

   Is there about +324 degrees to +396 degrees?

   YES 

   Go to step 5.

   NO 

   Replace the steering angle sensor .

5. Steering angle sensor performance check 4

   -1. Set the front wheels to the straight ahead position.

   -2. Check the parameter(s) below with the HDS while turning the steering wheel one turn to the left.

   Signal	Current conditions
   	Values	Unit
   STEERING ANGLE (CAN)

   Is there about -324 degrees to -396 degrees?

   YES 

   Go to step 6.

   NO 

   Replace the steering angle sensor .

6. Steering angle sensor check

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS.

   -3. Turn the vehicle to the OFF (LOCK) mode.

   -4. Test-drive the vehicle at 9 mph (15 km/h) or more.
