P0715 Help!

[Gottagetone]

I did a search and there is a closed thread about this code but the culprit was reset and never posted about again.

I am in Santa Fe and will be heading to Ouray tomorrow and when I started the truck this morning I threw the P0715 code. A search says input/turbine speed sensor circuit malfunction. The truck runs fine but I heard a crackle noise from under neath that went away but it threw the code again.

Any helpful info would be greatly appreciated!

I found this:

Question
Check Engine light has been On and Off for 2 weeks. P0715 "Input/Turbine Speed Sensor Circuit Malfunction" is the Trouble Code but I do not understand the description. Vehicle is 98 LandCruiser - 72K miles. 2UZ-FE.
What Sensor is causing the problem and what can I do about it?
Thanks, Ryan

Answer
There is a malfunction with the direct clutch input speed sensor or it's circuit, the computer compares this input signal with the number two speed sensor and so controls the shifting of the transmission, the most likely cause is that the speed sensor is the fault. It is also possible that there is a problem with the control module, there is a test procedure that requires the use of the Toyota hand held tester to see what the problem is, I recommend that you have the toyota dealer diagnose the problem and make a recommendation.

I'm looking forward to Ouray too, don't let this stop you! I've been in Montana the last few days and man this state is beautiful!!

I found that same thing. I just crawled up under the cruiser and everything looks fine so I am guessing that its a bad sensor. If the local dealership doesn't have one then I will call Durango, if they don't have one then I may have one overnighted to Ouray. A $200 dollar sensor is better than a new ECM or Tranny.

Matt Call Montrose Toyota also. I could pick up for you tomorrow on my way? Or Wed. AM.

Or call Groove in Englewood, I can pick it up when I get my oil changed today or tomorrow.

Took it to Beaver Toyota here in Santa Fe, they say it's a speed sensor but not the one I was thinking it was. They are overnighting the part and will hopefully fix it tomorrow so we can head on up to Ouray.

Rest day in Santa FE, ain't to shabby

 

[Gottagetone]

They pulled the sensor and founded metal shavings...ugh. We pulled the plug and all is clean, weird. I told em to put the new sensor in and refill the tranny and we will be on our way...fingers crossed!

Got, did you ever resolve this problem? Same code just popped up for me.

Bump for new answers....was the simple sensor the solution to all code?

 

[ponytl]

it was for mine... simple fast repair... slide under drivers side one bolt (12mm or 10mm i forgot) and one harness snap on connector, if you search this i posted here about what parts interchange, think i found mine on ebay for less than $25 there are several part numbers that look alike and will work but you have to elongate the bolt hole... it's just a simple magnetic pickup...

Thread seems vague on details...Which sensor is the culprit for the P0715 code?

 

[LBridges]

From the FSM section on diagnostics:
DTC P0715 Input/Turbine Speed Sensor Circuit Malfunction (O/D Direct Clutch Speed Sensor)


It's in the transmission, location illustration below.

Just (finally) replaced my sensor last Wednesday before a trip. Prior, the P0715 code would pop up within ~50-75 miles after clearing the codes out.

Happy to say, not one CEL after a 800 mile round trip

5 minutes start to finish.

Bad news...I replaced the sensor and the p0715 code popped right back on! Wiring appears to be ok...any suggestions?

just did the same thing. Did you ever figure out what the issue was?

Pull your output speed sensor and see if it has metal shavings on it too.
If so....clean it and reinstall. The two both send signals to the ECM that are compared.

Output was clean. I replaced it too cause I had another on hand.

Good deal. Probably time to look at the wiring of each then. Inspect visually for breaks, shorts. Then if that turns up nothing....I'd probe each 'hot' lead with a test light or use a multi-meter if you have one. IF you have power (correct voltage) going to each sensor...then we can move on to the next item.

That's what I'm hoping to find info on. I posted on my thread. Looking for info. Also a pic of the Chewed up input sensor that may or may not be troubling. I should have 12v on one lead. Does the car need to be cranked or just at ignition/accessory?

I don't know the answer to that. I would try first with only the ignition on. IF no voltage at either connector then, crank engine (parking brake on, wheels chocked) and go under.
