Replacement of tss sensor on a 07 ford edge

Turbine Shaft Speed (TSS) Sensor
The turbine shaft speed (TSS) sensor is a magnetic pickup that sends the powertrain control module (PCM) torque converter turbine speed information.
The TSS sensor is mounted internally on the center support.
The PCM uses TSS information to help determine electronic pressure control (EPC) and torque converter clutch (TCC) operation.
You have to remove and disassemble the transmission down to the center support to access.

What sensor do you think this code pertains too. ?
P0720 OSS Insufficient Input From OSS Sensor PCM detected a loss of OSS signal during operation. Harsh shift, possible abnormal shift schedule. Go To Pinpoint Test E . What makes you think it's the sensor ? Could be a wiring issue , PCM - engine computer .
Test Step Result / Action to Take E1 ELECTRONIC DIAGNOSTICS SET UP

• Check to make sure the transaxle harness connectors are fully seated, terminals are fully engaged in the connector and in good condition before proceeding.
• Connect the diagnostic tool.
• Key in ON position.
• Enter the following diagnostic mode on the diagnostic tool: Diagnostic Data Link.
• Enter the following diagnostic mode on the diagnostic tool: PCM.
• Select Trans Priority.
• Select PID/Data Monitor and Record.
• Select the following PIDs: TSS or 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 transaxle upshifts and downshifts through all gears.
• Does the TSS or OSS Speed PID increase and decrease with engine and vehicle speed?

Yes
GO to E3 .

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 STGT, sensor, a PCM concern or internal hardware concern. GO to E4 . E3 DRIVE CYCLE TEST ERRATIC

• While monitoring the appropriate sensor PID, drive the vehicle so that the transaxle upshifts and downshifts through all gears.
• Is the TSS or OSS Speed PID signal erratic (drop to zero or near zero and return to normal operation)?

Yes
If the sensor signal is erratic, INSPECT for intermittent concern in the harness, sensor or connector. GO to E4 .

No
CLEAR all DTCs. Rerun OBD. E4 CHECK POWERTRAIN CONTROL MODULE AND HARNESS FOR POWER

• Key in OFF position.
• Disconnect: TSS Sensor Connector.
• Disconnect: OSS Sensor Connector.
• Key in ON position.
• For TSS, measure the voltage between TSS sensor connector pin 1, harness side and ground; and between TSS sensor connector pin 2, harness side and ground.
• For OSS, measure the voltage between OSS connector pin 1, harness side and ground; and between OSS connector pin 2, harness side and ground.
  
• Is there any voltage?

Yes
GO to E5 .

No
GO to E6 . E5 CHECK HARNESS FOR SHORT TO POWER

• Key in OFF position.
• Disconnect: PCM Connector.
• Key in ON position.
• For TSS, measure the voltage between TSS sensor connector pin 1, harness side and ground; and between TSS sensor connector pin 2, harness side and ground.
• For OSS, measure the voltage between OSS connector pin 1, harness side and ground; and between OSS connector pin 2, harness side and ground.
  
• Is there any voltage?

Yes
REPAIR the circuit in question. TEST the system for normal operation.

No
INSTALL a new PCM. TEST the system for normal operation. E6 CHECK POWERTRAIN CONTROL MODULE AND HARNESS FOR GROUND

• Key in OFF position.
• Connect: PCM C415.
• For TSS, measure the resistance between TSS sensor connector pin 1, harness side and ground; and between TSS sensor connector pin 2, harness side and ground.
• For OSS, measure the resistance between OSS connector pin 1, harness side and ground; and between OSS connector pin 2, harness side and ground.
  
• Is the resistance greater than 10,000 ohms?

Yes
GO to E8 .

No
GO to E7 . E7 CHECK HARNESS FOR SHORT TO GROUND

• Key in OFF position.
• Disconnect: PCM Connector.
• For TSS, measure the resistance between TSS sensor connector pin 1, harness side and ground; and between TSS sensor connector pin 2, harness side and ground.
• For OSS, measure the resistance between OSS connector pin 1, harness side and ground; and between OSS connector pin 2, harness side and ground.
  
• Is the resistance greater than 10,000 ohms?

Yes
INSTALL a new PCM. TEST the system for normal operation.

No
REPAIR the circuit in question. TEST the system for normal operation. E8 CHECK RESISTANCE OF TSS SENSOR OR OSS.

• For TSS sensor, measure the resistance between TSS sensor connector pin 1, component side and TSS sensor connector pin 2, component side.
• For OSS, measure the resistance between OSS connector pin 1, component side and OSS connector pin 2, component side.
• Record the resistance. Resistance should be as follows:
  • OSS 675-775 ohms at -20°C (-4°F).
  • OSS 800- 920 ohms at 21°C (70°F).
  • OSS 1210-1390 ohms at 160°C (302°F).
  • TSS 273-333 ohms at -20°C (-4°F).
  • TSS 330-390 ohms at 21°C (70°F).
  • TSS 487-601 ohms at 160°C (302°F).
  
  
• Is the resistance within specification for the appropriate sensor?

Yes
GO to E9 .

No
INSTALL a new sensor. TEST the system for normal operation. E9 CHECK SENSORS FOR SHORT TO GROUND

• For TSS sensor, measure the resistance between TSS sensor connector pin 1, component side and ground.
• For OSS, measure the resistance between OSS connector pin 1, component side and ground.
  
• Is the resistance greater than 10,000 ohms?

Yes
INSTALL a new TSS sensor or OSS. TEST the system for normal operation.

No
REFER to Diagnosis By Symptom , for diagnosis of shift or torque converter concerns.

The one if front is the input speed sensor. The one behind is out put speed sensor. What was the code?

Hi Rusty, There's two links below showing the position of 2005 Ford Explorer Crankshaft Position Sensor and the 2008 ford edge camshaft sensor location. It seems like they're all in the same position, I hope this helps.....CHEERS

Remove the driver's side front wheel and the TSS will be clearly visible on the side of the automatic transaxle. It has a 2-pin connector and a retaining bolt. You may have problems in removing it, as they commonly corrode in place. I recommend the use of your favorite penetrating fluid, then tapping the sensor to try to get it to rotate a bit to free it up, and finally use a small screwdriver to try to pry it up as you rotate it.

Try to replace the sensor yourself. Its accessable throgh the left front wheelwell, next to the axle. It is a 8mm or 10mm bolt holding the sensor in. Good luck. Turbine Shaft Speed (TSS) Sensor Removal and Installation

1. Disconnect battery ground cable (14301) and positive battery cable. Refer to Section 14-01.
   

1. Raise and suitably support vehicle on hoist. Refer to Section 00-02.
   

1. Remove LH front tire and wheel assembly.
   

1. Disconnect turbine shaft speed (TSS) sensor electrical connector.
   

1. Remove one bolt and TSS from transaxle.
   

1. To install, reverse Removal procedure. Tighten TSS retaining bolt to 9-12 Nm (80-106 lb-in).
   
   

It should be sticking out of the top of the transmission at the rear of the unit. There are 2 sensors, 1 at front of unit (TSS) and one at the rear of the unit (OSS). The OSS is your speedometer related sensor.
