Pinpoint Test G: Turbine Shaft Speed (TSS) Sensor

WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The transmission control module (TCM) is integrated into the mechatronic assembly. If installing a new transaxle or a mechatronic assembly, the TCM will need to be checked and recalibrated (reflashed) to the latest level calibration available.

G1 ELECTRONIC DIAGNOSTICS
- Check to make sure the transaxle harness connector is fully seated, pins are fully engaged in the connector and in good condition before proceeding.
- Connect the scan tool.
- Key in ON position.
- Key in START position.
- With the vehicle in NEUTRAL and PARK at idle, monitor PIDs. (TR), (TSS_SRC), Pulley A (SPD_PULA) Speed TCCAMP_MES and (RPMTCM).
- The turbine shaft speed should be equal to engine speed, and pulley A (primary) speed should be at zero.
- Is the turbine speed equal to engine speed, and pulley A (primary) speed at zero?
Yes: If DTC P0811 is present, GO to PINPOINT TEST E . GO to G2.

No: GO to G2.
G2 ELECTRONIC DIAGNOSTICS
- With the vehicle in DRIVE and REVERSE at idle, monitor PIDs. (TR), (TSS_SRC), Pulley A (SPD_PULA) Speed and (RPMTCM).
- The turbine shaft speed should be equal to Pulley A (primary) speed.
- Is the turbine speed equal to pulley A (primary) speed?
Yes: System functionally correctly.

No: If TSS is zero and vehicle does not move, REFER to DIAGNOSIS BY SYMPTOM , No Forward and No Reverse. INSTALL a new mechatronic assembly. REFER to MECHATRONIC ASSEMBLY . (Refer to the NOTE preceding this pinpoint test.)
