fowis Posted June 6 Report Share Posted June 6 I have 2008 ford edge. I replaced the tss and oss sensors. After the replacement, the wrench light keeps coming on even at low speeds. Does the car just need more time for the relearning or there is something wrong with the replaced sensors. Quote Link to comment Share on other sites More sharing options...

garycrist Posted June 7 Report Share Posted June 7 What color is the transmission fluid? When was it changed, if ever and mileage of the Edge too? Does it shift right? Did the CEL ever go out after the parts replacement? Do you have rodent problem, as those little critters love to eat automotive wiring?

It looked almost new. I replaced it anyway with a new transmission fluid. Mileage is 212k. Wiring looked also fine when I replaced the sensors. What is CEL? 1 Quote Link to comment Share on other sites More sharing options...

garycrist Posted June 7 Report Share Posted June 7 CEL= Check engine Light or your "Wrench" icon. I dug up a video. I don't know if it helps. That is why the tranny questions. I have 210K on my 08 Edge with no problems. https://www.700r4transmissionhq.com/p0715-ford-edge/ 1 Quote Link to comment Share on other sites More sharing options...

That is why the tranny questions. I have 210K on my 08 Edge with no problems. After the replacement, the check engine light is always on and the wrench light comes back on as soon as I start driving the car. However, before the replacement, the check engine light and the wrench light were not coming on unless I drive on the highway above 70 mph. Thanks for the video. 1 Quote Link to comment Share on other sites More sharing options...

1004ron Posted June 8 Report Share Posted June 8 I recommend that you use Forscan Lite which should or might work with that OBDII adapter that you have - that way you'll have more confidence that all present codes are displayed. 1 Quote Link to comment Share on other sites More sharing options...
Haz Posted June 8 Report Share Posted June 8 Just curious if the vehicle exhibited any of the expected P0715 failure mode management symptoms beyond the Malfunction Indicator Lamp (MIL)... Good luck! 3 Quote Link to comment Share on other sites More sharing options...
fowis Posted June 9 Author Report Share Posted June 9 Yes, I experience the following symptoms: * harsh engagement * Poor launch performance * MIL is turned on On 6/7/2024 at 12:46 PM, 1004ron said: 1 Quote Link to comment Share on other sites More sharing options...
fowis Posted June 9 Author Report Share Posted June 9 I used also the Forscan software and I got code p0715 and code p0717. 1 Quote Link to comment Share on other sites More sharing options...
garycrist Posted June 9 Report Share Posted June 9 Time to get the volt meter out, as P0715 is an intermittent voltage loss and P0717 is FULL voltage loss. https://www.700r4transmissionhq.com/p0717-ford-edge/ 2 Quote Link to comment Share on other sites More sharing options...
fowis Posted June 13 Author Report Share Posted June 13 (edited) Voltage and resistance are checked. Harness wiring is ok. There are resistances between the transaxle connector C175T and sensors connectors so the Solenoid is also ok. There is 12 VDC at pin 2 of tss and oss connectors (Solenoid side). There is a reference voltage of 5 at pins 1 and 3 of the tss and oss connectors (Solenoid side). So, pcm is ok. Solenoid is ok Harness wiring is ok. I guess I need to replace the new installed tss and oss sensors. Edited June 13 by fowis Quote Link to comment Share on other sites More sharing options...
fowis Posted July 5 Author Report Share Posted July 5 I would like to share with you the reason for this problem. After removing the valve body I found the tss sensor is broken. During the installation, tss sensor got stuck between the valve body and transmission case. It has been pierced by the valve body and it broke as can be seen in the photo. Thank you. 1 Quote Link to comment Share on other sites More sharing options...
