DTC TURBINE REVOLUTION SENSOR
DTC TURBINE REVOLUTION SENSOR
DescriptionINFOID:0000000001703313
The turbine revolution sensor (power train revolution sensor) detects forward clutch drum rpm (revolutions per
minute). It is located on the input side of the automatic transaxle. The vehicle speed sensor A/T (Revolution
sensor) is located on the output side of the automatic transaxle. With the two sensors, input and output rpms
are accurately detected. As a result, optimal shift timing during deceleration and shift quality can be improved.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000001703314
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000001703315
• This is not an OBD-II self-diagnostic item.
• Diagnostic trouble code “TURBINE SENSOR” with CONSULT-III or 10th judgement flicker without CON-
SULT-III is detected when TCM does not receive the proper voltage signal from the sensor.
Possible CauseINFOID:0000000001703316
• Harness or connector
