DTC TURBINE REVOLUTION SENSOR
DTC TURBINE REVOLUTION SENSOR
DescriptionINFOID:0000000001694401
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.

4. Drive vehicle under the following conditions for more than 5 seconds.
SLCT LVR POSI: “D” position
VEHICLE SPEED: Higher than 40 km/h (25 MPH)
ENGINE SPEED: Higher than 1,500 rpm
THROTTLE POSI: Greater than 1.0/8 of the full throttle position
5. If the check result is NG, go to TM-104, "
Diagnosis Procedure".
WITHOUT CONSULT-III

REFERENCE VALUES
NOTICE:
1. The CONSULT-III electrically displays shift timing and lock-up timing (that is, operation timing of each
solenoid).
Check for time difference between actual shift timing and the CONSULT-III display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-III and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
- Actual shift schedule has more or less tolerance or allowance,
- Shift schedule indicated in Service Manual refers to the point where shifts start, and
- Gear position displayed on CONSULT-III indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-III at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).
