Welcome to FTE!!!
This could cause hard/abnormal shifts and/or no torque converter activation.
PINPOINT TEST E: TURBINE SHAFT SPEED (TSS), OUTPUT SHAFT SPEED (OSS)
CONDITIONS DETAILS/RESULTS/ACTIONS
NOTE: Refer to the Output Shaft Speed (OSS) Sensor Connector illustration preceding these pinpoint tests.
E1 ELECTRONIC DIAGNOSTICS
Check to make sure the transmission harness connector is fully seated, terminals are fully engaged in connector and in good condition before proceeding.
Scan Tool
Diagnostic Data Link
PCM
Select PID/Data Monitor and Record.
Select the following PIDs: TSS, OSS.
Does vehicle enter PID/Data Monitor and Record?
Yes
REMAIN in PID/Data. GO to E2 .
No
REPEAT procedure to ENTER PID. If vehicle did not enter PID, refer to the Powertrain Control/Emissions Diagnosis (PC/ED) manual for diagnosis of PCM.
E2 DRIVE CYCLE TEST
While monitoring the appropriate sensor PID, drive the vehicle so that the transmission upshifts and downshifts through all gears.
Does the TSS or OSS Speed PID increase and decrease with engine and vehicle speed or is the sensor signal erratic (drop to zero or near zero and return to normal operation)?
Yes
If the TSS or OSS Speed PID increase and decrease with engine and vehicle speed, CLEAR all DTCs. Road test to verify if concern is still present. If concern is still present, refer to the Diagnosis by Symptom Index in Diagnosis By Symptom for diagnosis.
If the sensor signal is erratic, INSPECT for intermittent concern in the internal/external harness, sensor, or connector.
No
If the TSS or OSS Speed PID does not increase and decrease with engine and vehicle speed, INSPECT for open or short in vehicle harness, sensor, a PCM concern, or internal hardware concern.
If the sensor signal is steady, GO to E3 .
E3 CHECK RESISTANCE OF TSS OR OSS SENSOR
Disconnect the appropriate vehicle harness connector from the OSS sensor. For the TSS sensor, disconnect the vehicle harness connector from the transmission.
For OSS: Connect ohmmeter negative lead to one pin of the sensor and the positive lead to the other pin on the sensor.
For TSS: Connect ohmmeter negative lead to the signal return pin and the positive lead to the TSS signal at the transmission connector.
Record the resistance. Resistance should be as follows:
Sensor Resistance (ohms)
TSS 64-126
OSS 305-735
Is the resistance within specification for the appropriate sensor?
Yes
Refer to the Diagnosis by Symptom Index in Diagnosis By Symptom for concern diagnosis.
No
REPLACE OSS and TSS sensor.
