DTC TURBINE REVOLUTION SENSOR
Description INFOID:0000000004305450
The turbine revolution sensor (power train revolution s ensor) detects forward clutch drum rpm (revolutions per
minute). It is located on the input side of the automat ic 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 resu lt, optimal shift timing during deceleration and shift quality can be improved.
CONSULT-III Reference Val ue in Data Monitor Mode INFOID:0000000004305451
Remarks: Specification data are reference values.
On Board Diagnosis Logic INFOID:0000000004305452
• This is not an OBD-II self-diagnostic item.
• Diagnostic trouble code “TURBINE SENSOR” with CO NSULT-III or 10th judgement flicker without CON-
SULT-III is detected when TCM does not receiv e the proper voltage signal from the sensor.
Possible Cause INFOID:0000000004305453
• Harness or connector (The sensor circuit is open or shorted.)
• Turbine revolution sensor (power train revolution sensor)
DTC Confirmation Procedure INFOID:0000000004305454
