TURBINE REVOLUTION SENSOR

TURBINE REVOLUTION SENSORPFP:31935
DescriptionBCS0012B
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. The result is optimal shift timing during deceleration and improved shifting.
CONSULT-II Reference ValueBCS0012C
On Board Diagnosis LogicBCS0012D
Diagnostic trouble code “TURBINE SENSOR” with CONSULT-II or 10th judgement flicker without CONSULT-II
is detected when TCM does not receive the proper voltage signal from the sensor.
