DTCS 11, 12, 13 & 14: Faulty Wheel Speed Sensor Input

NOTE: If after all testing procedures have been completed system is not functioning properly, substitute ECU with known-good unit and retest.
  1. DTC will set if ECU detects wheel speed sensor has no input signal. DTC will also set if wheel sensor voltage input is low while driving vehicle.
  2. Inspect installation of wheel speed sensor. If wheel speed sensor is loose or improperly installed, correct condition and go to next step. If no problem is found, go to next step.
  3. Disconnect ABS ECU harness connector. At harness side, measure resistance between specified wheel speed sensor terminals at ABS ECU harness connector. See WHEEL SPEED SENSOR OUTPUT CIRCUIT IDENTIFICATION INDEX  table. If any resistance value between any of the wheel speed sensor terminals is not within specification, repair damage and go to step  7 . If all wheel speed sensor terminals are within specifications, go to step  5 . See WHEEL SPEED SENSOR  under COMPONENT TESTS.
  4. Raise and support vehicle. Disconnect ABS ECU harness connector. Using DVOM, backprobe specified terminals at ABS ECU harness connector. See WHEEL SPEED SENSOR OUTPUT CIRCUIT IDENTIFICATION INDEX  . Check voltage between each terminal at ABS ECU harness connector while rotating wheel at 1/2 to one rotation per second. See WHEEL SPEED SENSOR OUTPUT VOLTAGE  . If pulse voltage is within specification, go to step  7 . If voltage is not as specified, go to next step.
  5. Disconnect wheel speed sensor connector. Using DVOM, check resistance across sensor terminals. Resistance should be within specifications. Check resistance between each sensor terminal and sensor body. Resistance should be 100 /k ohms or more. If resistance is not as specified, replace sensor and go to step  7 . If resistance is as specified, go to next step.
  6. Inspect wheel bearings for looseness or any other damage. If any damage or looseness is found, replace or repair as necessary and go to next step.
  7. Connect MUT II tester to Data Link Connector (DLC). Retreieve any DTCs. Verify that DTCs 11, 12, 13 and 14 do not reset.
