CHECK TORQUE CONVERTER TURBINE SPEED SENSOR
Turn the ignition switch to OFF.
Disconnect the connector from transmission.
Measure the resistance between transmission connector receptacle's terminals.
Connector & terminal
(T4) No. 5 - No. 10
Is the resistance 450 - 650 O?
YES. Go to CHECK HARNESS CONNECTOR BETWEEN TCM AND TRANSMISSION .
NO
Replace the torque converter turbine speed sensor.
Move the select lever to "P" or "N" range.
Idle the engine.
Does the turbine speed sensor revolution displayed by Vehicle Diagnostic Interface almost correspond with engine revolution indicated by tachometer?
YES
There are malfunctions in TCM, TCM connector poor contact, or transmission assembly mechanical malfunction.
NO
Check the torque converter turbine speed sensor circuit.
Move the select lever to "P" or "N" range.
Idle the engine.
Does the engine revolution displayed by Vehicle Diagnostic Interface almost correspond with engine revolution indicated by tachometer?
