Hi there:
Make sure the TSS sensor connector is good. Since you replaced the engine it is possible the wires/pins in the connector are loose or bad. I have seen where the wires break inside the insulation at the connector.You could have a bad TSS sensor (200-400 ohms good), if you have a multi meter we can check the circuits too. I would check the connector and then clear the code , test drive and see if it comes back. The PCM uses this sensor to control shift patterns so a fault is stored in the PCM. P0715 is for a loss of TSS signal during operation.

we can check the continuity but that will only show if there is high resistance. If there is a wire about to break(instead of 15 strands connected 3 or 4) we need to load the circuit or wire. If we put 12 volts through the wires(disconnected from the sensor and PCM of course) and we use a light bulb as a load if the wire is bad the bulb will be dim. I would start with an ohm check of the sensor and a close inspection of the connector.

We start with an ohm test on the sensor and then continuity test the circuit. Then we load the circuit. I have had the wires break as I disconnected the connector or tugged on the wires at the connector.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

SOURCE: I have a code p0715, which is the input turbine speed sensor

Have the same problem with the input speed sensor. The part, so far, is only made by Mitsubishi (Part No. 8651A111) and cost about $110 (w/ tax in TX).

SOURCE: turbine input speed sensor

NO the sensor is out side the transmission. And it might just be a bad connection due to being out in the eliments. On the 3.1 your going to have to jack up the car to get to it from underneath and you should see it on the passenger side may be on top, Sorry been awhile and carful not to brake the clips that hold the wire to the sensor when disconnecting.
Good luck and hope this helps

SOURCE: input/turbine speed sensor circuit

Your speed sensor, is located on top of the transaxle, near the starter. To access it, remove the battery, then remove the battery tray (4 10mm bolts). You will see wires coming from the lower oxygen sensor, and they snap into the bracket that holds the speed sensor in place. The actual speed sensor has a 2 wire clip on it, and is held in place by the bracket and a 10mm bolt.

SOURCE: code 715 is reading it

If u go to the link below there u will find a diagram of the transmission, the Turbine speed sensor is part #5 in the diagram, it has an electrical connector going to it.

2006 Jeep Grand Cherokee. DTC P2767. Is the probable cause in the transmission or external?


the code means.
to do the tests listed in the fsm. book, not guess.
we do the tests, and find out if the cause in in the transmission
the TCM or the TCM sensors or the solenoid drivers or solenoids
or the actual transmission internals.
why guess? why ask folks to guess. who are blind.?
ever seen the book, and read , the chapter on A/t trans on car tests?
alldata.com or
free

i guessed drive line... so....

the book hints at....
- Faulty Input Speed Sensor 2 ,.is dead.
- Input Speed Sensor harness is open or shorted
- Input Speed Sensor circuit poor electrical connection

The Input Speed Sensor 2 is one of the two hall effect speed sensors that are used by the Transmission Control Module (TCM) to calculate the transmissions turbine speed. Since the turbine speed could not be measured directly, two of the drive elements are measured. Two input speed sensors are required because both elements are not active in all gears.

Location of trans speed sensor 3 pin location 2004 solar v6 automatic p0500 speed sensor trouble code


no what matters is if the pulses are good.
and the transmission not slipping.
the TCM is not genious level yet.

are you asking what P0500 means.
or want us to tell you all things stated in fSM for this code.
what? guessing you can do .
ever heard of alldata.com (DIY)
ever read that page on 500s?
i guess not.
3.3L v6 ?
quote:
Trouble Code Conditions: P0500
VEHICLE SPEED SENSOR "A"
The ECM detects following conditions simultaneously for 2 secnonds (1 trip detection logic):
No SPD (speed sensor) signal while ECM detects NC (trans­mission counter gear) signal is more than 300 RPM Park/Neutral position switch is OFF (When shift lever is in other than P and N positions) Possible Causes:
  • Open or short in speed sensor circuit
  • Speed sensor
  • Combination meter
  • ECM
  • Skid control ECU
im trying to decode that too, the sensors
are called, C3 counter gear sensor, and Turbin T3 sensor
but the book keeps changing names in the book.

i think it means, counter gear shows correct RPM
but the turbine gear sensor T3 is dead.
while in gear. is too hard for them to say. so i said it.
and my guess, moving,
after all transmission slip moving
in fact i can scan your car and prove that
i scan it in park, then indrive, no moving
got 500s, or are 500 happening flogging engine.

but the ECU signal is either dead for turbine sensor or is way too slow. see incongruity from 300+ rpm on counter gear.

500 means dead, not intermittant.
i looked at all codes for turbine.

so my best guess (no real fsm only alldata)
is Turbine is the clutch sensor. (input rpm to trans-clutch)
and counter gear is tail shaft sensor.? (output speed)
so the front clutch sensor is dead
or being grounded out, or is not connected, (rusty conns?)

Most FSM made do a poor job, at showing possible bad parts.

here is better
  1. the sensor is weak or dead
  2. the sensor connections are bad.
  3. the sensor, signals do not arrive at the PCM /TCM, due to bad wires, or anything on that line shorting that line out.
  4. better (yes?, this is electronics) no a parts swap game.

if the car drives ok then the trans does not slip.
the TCM sees both ends and can detect, bad sensors or gross slip.
i think it means bad sensor. in this case only.

what does this mean?
  1. having difficulty locating it
can buy one, find one, can't insert it, or?

Where does the turbine input shaft speed sensor go on a 2010 cevy malibu Lt


Chances are that this sensor is located in the transmission or has access to it outside the housing.Take the car to a transmission specialist and have them give you an estimate.Most dealerships these days don't even do trany work anymore so save yourself some money and go directly to someone who can help you.good luck

Hi Mario, I may be behind times, but believe the sensors you're referring to are the turbine pressure sensors. There are usually two, mounted onto he turbo inter-cooler. Regards John.

Lost pwr for takeoff, and gauges all going haywire and overcharging battery


Did the overcharge or voltage regulator problem go away with the new ECM in it? If so the transmission code.. (turbine speed sensor input) code is probably another problem that the Jeep has.. and the ECM will not fix that, but the input speed sensor that it may need is not very expensive.

Transmission code error P2716


The computer wants to know if the transmission is working properly. So it reads the speed of the input shaft and compares it to the speed of the output shaft. It knows which gear you're in because it commanded the transmission to shift into that gear. The turbine speed refers to the torque converter. That's the device that transfers power from the engine to the transmission. Think of two fans facing each other. Turn on one fan and the blades on the other fan will spin. The fan that ISN'T turned on is the turbine. So, with the input shaft or turbine speed, the gear selection, and the output speed, the computer can calculate how efficiently the transmission is working. If the speed is off, it knows that something is slipping inside the transmission. It can then try to boost the fluid pressure to compensate. If that doesn't work, it sets a different trouble code, usually a P0716 code means that the computer has detected a value for the input sensor that's either out of range (way too high or too low), or there's a circuit issue (bad wiring, etc. Should probably get it to a repair shop ASAP before damage is done.
