Turbine Revolution Sensor Circuit

TURBINE REVOLUTION SENSOR CIRCUIT CHECK
Description
The turbine revolution sensor detects input shaft rpm (revolutions per minute). The sensor is located on the input side of the automatic transmission. The vehicle speed sensor A/T (Revolution sensor) is located on the output side of the automatic transmission. With the two sensors, input and output shaft rpms are accurately detected. The result is optimal shift timing during deceleration and improved shifting.

Diagnostic Trouble Code (DTC) confirmation procedure
After the repair, perform the following procedure to confirm the malfunction is eliminated.




With CONSULT
1) Start engine.
2) Select "SELF-DIAG RESULTS" mode with CONSULT.
3) Drive vehicle under the following conditions:
Selector lever in D, vehicle speed higher than 40 km/h (25 MPH), engine speed higher than 1,500 rpm, throttle opening greater than 1/8 of the full throttle position and driving for more than 5 seconds.




Without Scan Tool
1) Start engine.
2) Drive vehicle under the following conditions:
Selector lever in D, vehicle speed higher than 40 km/h (25 MPH), engine speed higher than 1,500 rpm, throttle opening greater than 1/8 of the full throttle position and driving for more than 5 seconds.
3) Perform self-diagnosis.
Refer to SELF-DIAGNOSTIC PROCEDURE WITHOUT CONSULT OR GST.
