Turbine speed sensor

I have2014 tundra 5.7 v8 sr5. Check engine light came on aswell traction control off message. Code p0717 comes up says turbine speed sensor. I am out of warranty so I’m trying to fix on my own. Anyone know where the sensor is located or how to fix

 

Did some brief digging. Looks like a conventional code that on most Toyota's points to a speed sensor.

Wheel speed sensor?
Vehicle speed sensor?
Engine speed sensor?

I don't know. I just google searched some other Toyota forums since most of the codes are generic.

 

That’s what I’ve been doing. Trying to get an answer as to where the turbine sensor is located. Guy at dealer thinks may be internal. If it is I’m screwed. Still waiting for call back.

 

It should be visible. More simple google digging points to a speed sensor on the transmission somewhere. Use google, Youtube, or wait for someone to chime in who has also had this exact problem.

 

Havent really been under a tundra before but sounds/looks like a sensor near bellhousing that takes a read off inputshaft or tourqe converter. Acts like a magnetic pick up sensor, sensor may have gone bad itself causing a no signal code

 

I’ve tried YouTube and google can’t get an answer but dealer called back and told me it’s located on top of transmission but kept insisting I bring it in for diagnostic

 

Ome of the components inside a tourqe comverter is called a turbine and it is also monitored by sensors and such. That fact that it is giving a code for no signal at the sensor makes no sense im sure that turbine is spinning (bolted to flexplate and locked into pump on the front of trans) my guess is bad sensor. 2014 truck shouldnt havhave a wiring problem already. Im sure its located on side or top of trans case at the fromt of case.

 

I haven’t noticed any difference in performance of my truck. Still runs like a beast. Just don’t wanna spend an unnecessary amount of money at dealer

 

You probably wont if anything you may notice a difference in shift points. That is just a sensor issue the rest of the components i mentioned are mechanical the sensor just monitors ot but the light is a bother and you dont want to cause issues id just throw a mew sensor in it and call it a day. Can't be too much of a pain, probably held in by a 10mm and a O-ring

 

If im wrong or sound like i dont know what im talking about someone correct me lol i am pretty sure i was spot on

 

From what I’ve found sounds pretty good. Just gotta figure out how to get to it

 

As far as this code.. Just popped up on my 2012 Tundra.. I have the extended warranty on the truck and take it in this week.. The only mod I have on it is a BAM 8inch exhaust system.. Is there a correlation between the change of exhaust and Turbine/Input Shaft speed sensor A Circuit (no signal)? I m hoping Toyota covers this claim.. Thanks in advance guys! Sorry for the double post in another thread

 

P0717 NO SIGNAL OF TURBINE SPEED SENSOR A.Code ! DO NOT BUY THE AMAZHON IN PUT SPEED SENSOR even it's cheap 21 Canadian dollars, END WITH THE WRONG PARTS CAN NOT BE INSTALLED! EVEN IT SAY IT FIT YOUR 2014 TUNDRA .Today in Toronto the weather is very good, I tried to installed the parts which is above the coolant pump ( I guess , I saw two black coolant hose goes there) , the job is not that hard if you don't have a huge hand. I used flexible head rachet 10'mm, and spend some time to clean the bolt, the job was not that hard to do, I use a long screw driver to take out the sensor (a little bite to the transmission body) I had check resistance read 667 om, looks good, compared with Amazon it read 670 om, but Amazon sensor the fastening is a straight line one ,it would not fit , the original Toyota had 45 degree. The hardness connector not long enough to reach there, if you want use this parts you had do cut the connector to extend the wire in this way you can connect, I did not do this way , because I love this truck, I reset the code and drive to Don Valley Toyota , the check engine light went on after 3 KM, I had paid 235.00 for the QEM parts had do wait above a week, I will update what happen after I stalled the new parts.

 

I had to resolder in a 15 pin connector to transmission (rodent damage).... one wire came loose.... p0717 error. Check the 15 pin connector.... driver side, side of transmission

Check this other thread with the same error code. I posted pictures of where the sensor is. I bought an aisin sensor to replace mine and have had no issues.

 

I found this old thread while trying to resolve the above issue with my 2010 Tundra. I bought the input turbine speed sensor but for the life of me can't find where it's located. I checked out a photo of the location but it appears that at that location on my truck there is a recess where maybe the sensor could go, but it doesn't appear that anything was ever mounted there. I did locate the aft sensor. Would there be any reason for no forward sensor to have been installed? Thanks!

 

Found what appears to be the forward sensor on the opposite (drivers) side of the transmission. Could that be the correct sensor? Found an illustration of a transmission that seems to go along with sensors on both sides of the tranny:

 

My 2014 just had the same code, and if you pull the front input speed sensor, you should find that the ohm readings are off. I had already changed the output speed sensor from another code, and the one I pulled was fine. In any case, both were 10 years old, and replacing both was something to consider.

The front input sensor was bad, and the ohm readings supported replacing it. The rear output speed sensor was fine, ohms within spec, and continues to function. Both sensors are the same part #, input above the cooler thermostat, and the rear one is above the shift cable bracket, both of which are on the passenger side of the trans (4x4) truck

 

Thanks. I'll keep looking for the forward sensor. Any idea what the sensor (that looked just like the input speed sensor) on the other side of the transmission would be?

 

On my 14, both input and output are the same part number. You can see I,checked them for ohms, and notated each box. The .587 unit gives a reading that pops a code 0717, so it will never be used again. 11 years of service was enough.

Aisin seems to be the goto brand, IMHO



In all liklihood "seeing" the sensor is a real pain, as the trans cooler thermostat gizmo is in the way. I found it by feel, and being a contortionist for a few moments. A 10mm wrench, a light tug, then a snap noise, being pleasantly surprised the bolt had NOT seized in the trans housing. Cleaned the surface with a rag, coated the new sensor with ATF on the oring, then popped the new sensor in, never seize on the bolt threads, and tightened to "just enough". Plugged in, and code 0717 was gone

 

Thanks again. Still looking for it.
