All you need to do is use Google to ask your questions

It's all there in print,video, as well a some answers on Wikipedia

You Tube Video--is something you should use every week for
something

This took me all of about 15 seconds to look up on google. Make an effort. Please.

Ford P0715 OBD-II Trouble Code Definition:
P0715 Input Shaft Speed Sensor Circuit Malfunction
P0715 Ford OBD-II Trouble CodeDescription:
OBD Trouble Code P0715 Input/Turbine Speed Sensor "A" Circuit What does the code mean? OBD-ii Code P0715 definition:
The input speed sensor detects the primary pulley revolution speed and sends a signal to the Transmission Control Module (TCM) and Engine Control Module (ECM). Symptoms Sumptoms of OBD code P0715
- Engine Light ON (or Service Engine Soon Warning Light) - Possible shifting problems Causes Causes of the OBD-II code P0715
- Transmission speed sensor circuit is open or shorted. - Poor transmission speed sensor circuit connection - Faulty transmission speed sensor The Error code is generally activated on detection of the following conditions: Diagnostic Trouble Code (DTC) P0715 is detected when TCM or ECM does not receive the proper signal from the sensor. Solutions

input speed sensor for transmission is faulty which will throw the 717 code and when it does it will also tell "root" TCM (transaxle control module) to include the 700 code.
700 happens when it detects an issue with the TCM.
717 happens when the sensor is bad.
- Faulty Transmission Speed Sensor
- Transmission Speed Sensor harness is open or shorted
- Transmission Speed Sensor circuit poor electrical connection

code p0847 refers to transmission fluid pressure (TFP) sensor B--low input===causes--wiring---short to ground---TFP sensor--ECM/TCM

Try replacing the sensor and checking the wiring. After that check the transmission control module (TCM)

code p0700 refers to transmission control system/MIL --malfunction===causes --wiring ---TCM (1)
code po740 refers to torque converter clutch (TCC) solenoid--circuit malfunction===causes--wiring--TCC solenoid--ECM/TCM (transmission control module) (again)
code p0871 refers to transmission fluid pressure (TFP) sensor C -range/ performance problem==causes---wiring--poor connection--TFP sensor--ECM /TCM (yet again)
code p0734 refers to gear 3 ratio (po374 is gear ratio 4) incorrect ratio===causes --wiring--TR sensor/switch--shift solenoids--transmission mechanical fault (causes are the same for po733&734)
code po846 refers to transmission fluid pressure (TFP) sensor B-range/ performance problem===causes ---wiring--poor connection--TFP sensor--ECM/TCM (again). Give the clutch a miss as you still have 1st gear and if the clutch is not working you will not be going any where. Have a pressure test done on the transmission to check for internal mechanical failures (pump ). The rest are sensors are wiring connections , sensor and TCM. My bet is the TCM unit. Have it checked out. What ever you do treat any suggestion of a new transmission with a grain of salt until you are shown proof positive that you need one.

P0715 MAZDA - Input Turbine Speed Sensor Circuit Malfunction.


http://engine-codes.com/p0715_mazda.htmlForum CodePossible causes- Transmission speed sensor circuit is open or shorted.
- Poor transmission speed sensor circuit connection
- Faulty transmission speed sensor When is the code detected?Diagnostic Trouble Code (DTC) P0715 is detected when TCM or ECM does not receive the proper signal from the sensor.

p0708 is transmission range sensor curcuit high output, p0171 is system to lean ( bank 1 ), p0442 is EVAP emission control leak ( small ).

Transmission Input Speed Sensor (G182 VAG com code): Circuit Malfunction
The Input Turbin Speed Sensor is located inside the transmission, the code can be caused by a failed sensor or sensor wiring or a slipping transmission.
