No Signal From Right Front Sensor
Symptom List:
NO SIGNAL FROM LEFT FRONT SENSOR
NO SIGNAL FROM RIGHT FRONT SENSOR
Test Note: All symptoms listed above are diagnosed using the same tests. The title for the tests will be NO SIGNAL FROM LEFT FRONT SENSOR.
When Monitored and Set Condition:
NO SIGNAL FROM LEFT FRONT SENSOR
When Monitored: Wheel speed comparison is checked at drive off or every 7 milliseconds (ms). Sensor circuit continuity is checked every 7 milliseconds. Wheel speed phase length supervision is checked every 7 milliseconds.
Set Condition: If, during an ABS stop, the CAB commands any valve solenoid on for an extended length of time, and does not see a corresponding wheel speed change, the Diagnostic Trouble Code (DTC) is set. The DTC can also set if the signal is missing or erratic.

POSSIBLE CAUSES
CAB--SETTING FALSE DTC
SPEED SENSOR OR CONNECTOR DAMAGED
TONE WHEEL DAMAGED
WHEEL SPEED SENSOR AIR GAP OUT OF SPECIFICATION
WHEEL SPEED SENSOR INOPERATIVE
CAB - WON'T RESPOND TO FRONT WHEEL SPEED SENSOR SIGNAL
INTERMITTENT SIGNAL DTC
