Study Guide and Component Location Study Guide and General Description Study The Output Speed Sensor outputs pulse-signals according to the revolutions of the output shaft of the transmission. Study The Output Speed Sensor is installed in front of the Transfer Drive Gear to determine the Transfer Drive Gear rpms by counting the frequency of the pulses. Study This value, together with the throttle position data, is mainly used to decide the optimum gear position. Study Guyide and DTC Description Study The TCM sets this code if the calculated value of the pulse-signal is noticeably different from the value calculated, using the Vehicle Speed Sensor output, when the vehicle is running faster than 30 km/h. Study The TCM will initiate the fail safe function if this code is detected. Study Guide and DTC Detecting Condition Item Detecting Condition Possible Cause DTC Strategy Study ● Speed rationality check ● Signal circuit is open or short. ● Sensor power circuit is open ● Sensor ground circuit is open ● Faulty OUPUT SPEED SENSOR ● Faulty PCM Study Enable Conditions ● Battery Voltage ≥ 10V ● Lever position : D,3,2,L ● State of brake : OFF Study Threshold Value ● Output speed = 0 Study Diagnostic Time ● More than 1sec Study Fail Safe ● Locked into 3rd or 2nd gear. ● Manual shifting is possibe(2 nd → 3 rd ,3 rd → 2 nd) Study Specification Input shaft & Output shaft speed sensor ● Type : Hall sensor ● Current consumption : 22mA(MAX) ● sensor body and sensor connector have been unified as one.

Study Guide and Terminal and Connector Inspection 1. Study Many malfunctions in the electrical system are caused by poor harness and terminals. Faults Study can also be caused by interference from other electrical systems, and mechanical or chemical damage. 2. Study Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. 3. Study Has a problem been found? YES 1) Repair as necessary and go to "Verification Vehicle Repair" procedure NO 1) Go to "Signal Circuit Inspection" procedure Study Guide and Signal Circuit Inspection 1. Study Ignition "ON" & Engine "OFF". 2. Study Disconnect the "OUTPUT SPEED SENSOR" connector 3. Study Measure voltage between terminal "2" of the OUTPUT SPEED SENSOR harness connector and chassis ground. A. Specification : Approx. 5V 4. Study Is voltage within specifications ? YES 1) Study Go to "Power Circuit Inspection" procedure NO 1) Study Check for open or short in harness. Repair as necessary and Go to "Verification Vehicle Repair" procedure 2) Study If signal circuit in harness is OK, Go to "Check PCM/TCM" of the "Component Inspection" procedure. Study Power Supply Circuit Inspection 1. Study Ignition "ON" & Engine "OFF". 2. Study Disconnect the "OUTPUT SPEED SENSOR" connector 3. Study Measure voltage between terminal "3" of the OUTPUT SPEED SENSOR harness connector and chassis ground. A. Specification : Approx. B+ 4. Study Is voltage within specifications ? YES 1) Study Go to "Ground Circuit Inspection" procedure NO 1) Study Check for open in harness. Repair as necessary and Go to "Verification Vehicle Repair" procedure Study Guide and Ground Circuit inspection 1. Study Ignition "ON" & Engine "OFF". 2. Study Disconnect the "OUTPUT SPEED SENSOR" connector 3. Study Measure resistance between terminal "1" of the OUTPUT SPEED SENSOR harness connector and chassis ground. A. Specification : Approx. 0 Ω 4. Study Is resistance within specifications ? YES 1) Study Go to "Component Inspection" procedure NO 1) Study Check for open in harness. Repair as necessary and Go to "Verification Vehicle Repair" procedure 2) Study If ground circuit in harness is OK, Go to "Check PCM/TCM" of the "Component Inspection" procedure
