Question about Cars & Trucks
Ok i locate my turbine speed sensor , how do i know if is bad, how can i test it?????? do i have to check the terminals for resistence??????
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.

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).

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

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.

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.
