Speed Sensor Turbine Sensor
Setting Condition:
When the vehicle speed exceeds 5 km/h with the turbine speed over 1000 rpm for 5 seconds, after 25.5
seconds elapsed in D, 3, 2 or L range.
Fail Safe:
When the vehicle is running, the gear position selected at the trouble detection is held and the lock-up is
inhibited.
After the vehicle stopped, all solenoid operations stop (OFF) and the gear is fixed to the 3rd.
Possible Cause:
Speed sensor malfunction.
Sensor wheel (parking gear) malfunction.
Large sensing gap between speed sensor and sensor wheel (parking gear).
Sensor wire open circuit, short circuit to battery or short circuit to ground between speed sensor terminal 1 and
TCM terminal B13 (C95).
Sensor wire open circuit or short circuit to ground of the harness between speed sensor terminal 2 and power
supply circuit.
Sensor wire open circuit or short circuit to battery between speed sensor terminal 3 and ground circuit.
Poor connection of each connector.

Speed Sensor Turbine Sensor
Setting Condition:
The turbine speed below 300 rpm for 2 seconds while the vehicle is running at the speed over 40 km/h with the
engine speed over 1500 rpm in the D, 3, 2, or L range.
Fail Safe:
When the vehicle is running, the gear position selected at the trouble detection is held and the lock-up is
inhibited.
After the vehicle stopped, all solenoid operations stop (OFF) and the gear is fixed to the 3rd.
Possible Cause:
Turbine speed sensor malfunction.
Sensor wheel (reverse & high clutch drum) malfunction.
Large sensing gap between speed sensor and sensor wheel (reverse & high clutch drum).
Sensor wire open circuit, short circuit to battery or short circuit to ground between turbine speed sensor terminal
1 and TCM terminal B3 (C95).
Sensor wire open circuit or short circuit to ground between turbine speed sensor terminal 2 and power supply
circuit.
Sensor wire open circuit or short circuit to battery between turbine speed sensor terminal 3 and ground circuit.
Poor connection of each connector.

DIAGNOSIS (JR405E) 7A2-119
Step Action Yes No
8 Inspect the output signal of the speed sensor using a Tech 2 or
circuit tester.
Is the data display in the Tech 2 correct or output voltage correct
in the circuit tester?
