The Output Speed Sensor outputs pulse-signals according to the revolutions of the output shaft of the transmission. 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. This value, together with the throttle position data, is mainly used to decide the optimum gear position.
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.
Item | Detecting Condition & Fail Safe | Possible cause |
DTC Strategy | ● Speed rationality check | ● Signal circuit is open or short. ● Sensor power circuit is open ● Sensor ground circuit is open ● Faulty OUTPUT SPEED SENSOR ● Faulty PCM |
Enable Conditions | ● Vehicle speed is over 19 Mile/h(30 Km/h) in D,3,2,L(A/T range swhitch) and SP(SPORTS MODE) ● But do not check the DTC in below condition - A/T oil temp sensor voltage ＞4.5 V - Eng revolution ＜ 2600 rpm (In 1st or 2nd gear) | |
Threshold value | ● If the output from the output speed sensor is continuously 50% lower than the value calculated by vehicle speed sensor. | |
Diagnostic Time | ● more than 1sec | |
Fail Safe | ● Locked into 3rd or 2nd gear. ● Apply an electric current to Solenoide valve ● Manual shifting is possibe (2 nd → 3 rd ,3 rd → 2 nd) |

Connect scantool to data link connector(DLC)
Engine "ON" .
Monitor the "OUTPUT SPEED SENSOR" parameter on the scantool
Driving at speed of over 19 Mile/h(30 Km/h)
Specification : Increasing Gradually
Does "output speed sensor " follow the referance data?
▶ Fault is intermittent caused by poor contact in the sensor's and/or TCM(PCM)'s connector or was repaired and TCM(PCM) memory was not cleared. Throughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or
▶ Go to "W/Harness Inspection" procedure
Many malfunctions in the electrical system may be caused from poor harness and terminals. These faults can be caused by interference from other electrical systems and mechanical or chemical damage.
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
