Loss of power of EDGE 2008. Help to understand to the colleague.

[EDST777]

Hi, firends. I ordered two sensors for replacement a week ago, it will be TSS/OSS. Lately three more or four times with breaks through two, three days, during the movement the signal on the panel "Powertrain malfunction/reduced power" shines. After restart of the engine I continued a driving. But last night to "Powertrain malfunction/reduced power" was added "Service Engine Soon" or as it is called still by "check engine". I did restart and now at me on the panel "Service Engine Soon" constantly burns. My sensors in way to me, I wait for them receiving, it can be a week more, two. I can do a driving every day on 15-20 km with such shining an inscription on the panel " check engine" ( I am afraid for transmission)? Thanks, any thoughts.

P.S: I did a trip this morning on operation, no discomfort existed, operation of transmission seemed normal, but I am confused by the shining sign "Service Engine Soon"

Maybe it finally set a code or codes from the TSS/OSS failure? I'd check those first.

Thanks. I will check the version that the code perhaps "is caught" using diagnostics. I think to continue daily trips (15-20 km a day) until I receive sensors for changeover?!

To be honest, IMHO it's risky, more so because you have AWD. If the computer is acting on incorrect data, you can get some harsh shifting, which could lead to costly repairs.

having read these mistakes, I caught malfunction of the TSS sensor! I am glad that there is no malfunction of the OSS sensor. But friends, my second news: I received the shipped TSS/OSS sensors (couple) yesterday. Now I think as better to do work? To replace only TSS (a mistake only on it) or to replace two TSS and OSS sensors? Your thoughts, please!

P.s.: This detailed description received at diagnostics.

Status:

- Previously generated DTC which is absent at the time of inquiry

- The indicator lamp of malfunction is switched off for this DTC

Module: Module of system of classification of the driver / passenger

Detailed description of an error code of diagnostics

Malfunction, half-scientific from external knot

It is DTC it can be caused:

Short circuit in the CAN line.

Rupture of a chain in the CAN line.

There is a delay in data exchange between two modules on the tire CAN

There are hindrances in the tire CAN

There can be other modules in data line of CAN which don't participate in data exchange and aren't synchronized.

Notice:

DTCs which begin with 'U' correspond to malfunctions which arise in the presence of communication of the module with the module.

Never it is necessary to replace modules only on the basis of 'U' - a code. These codes not always speak about existence of a problem and can be caused by the usual diagnostic functions which are carried out on the car.

=== 4X4M DTC Isn't present ===

Successful reading codes of mistakes (DTC), errors isn't noticed.

Since you have already done most of the work getting to one sensor, why not do the other one at the same time? Simple practicality. Nothing to think about, just do it

[EDST777]

Thanks............ Repeat))) Friends, when replacing the OSS sensor in procedure (a step 10) it is specified:

NOTE: The coolant hoses do not need to be removed from the engine.

Remove the coolant hoses from the transmission fluid filler tube and position aside.

 

 

Whether my question: needs to be deleted cooling liquid? I think to pump out through a broad tank before separating hoses which are specified on the image. What your opinion?

My uneducated guess would be that you rotate the hoses such that you can remove the fill tube. So, for each hose, should only need to squeeze the clamp, rotate the hose, release the clamp. Return to original position (take a pic how they sit in your engine before hand) after reinstalling the fill tube when instructed.

[EDST777]

Thanks!

I have made it, but in two steps, I regret that has not listened to you, it would help me not to do excess work). In November, 2015 I have replaced the TSS sensor, till April everything was normal, without mistakes, but in April the problem has appeared again, this time there was OSS error (which did not shine earlier). Now I have replaced the OSS sensor. Interestingly, it is natural, the period of replacement of sensors of 70000-100 000 km or it was a production defect of sensors, there is a wish to know why they break also what influences it? If it is each 100 000 km, then Ford has to write down it in scheduled works)!

[WWWPerfA_ZN0W]

Well, hard way to learn, but I hope the transmission will now be troublefree for another 100,000 KMs (or more)! No idea why they go bad except to note that don't believe the "lifetime transmission fluid" marketing ploy. Definitely change it out every 60,000 miles (or less if "severe service" qualifies). Varnish does build up in the transmission over time as the fluid gets old and the additives break down. Electronic components are VERY sensitive to this gunk and the easiest way to keep them clean is to change the fluid periodically.
