Hi, i have an error for my LS430. P0715 Input/Turbine Speed Sensor Circuit Malfunction. I have change the speed sensor and checked the socket but error still come back after few days later. Ant idea?


This is different from speed sensor ! Which sensor did you replace the one on out side of transmission . Turbine speed sensor is inside transmission .

I am looking for a ECU pinout or a Diagram. I am throwing a "turbine overspeed" code (P0716) on a non turbo car. Also P0721 and P0705 On second ECU with the same issue.


Hello. You are confusing the turbine over speed control sensor module of the car's transmission, with a turbo charger- a forced air induction device, of a car's engine. One has nothing to do with the other.

The turbine over-speed control module is basically a sensor that reads the speed of the transmission's input shaft (torque converter) in relation to the speed of the output shaft- transmission speed ratio/gear.

Simply put- when the P0716 error code displays, it means that the ECM has detected the value(s) of the input sensor as being out of range, like being too high or too low; or that there is some bad wiring issue in the circuit.

When this happens, the subsequent P0721 output speed sensor and P0705 transmission range sensor circuit malfunction error codes appear- and does not necessarily mean that the entire transmission components (electronic modules, sensors, or mechanical parts) have malfunctioned leading to a major transmission overhaul.

It is most likely that the Input Turbine Speed sensor needs to be replaced. Take the car to a well qualified SAE certified transmission specialist who has precise diagnostic and transmission control readers and are able to reset the computerized transmission modules once the repair is made.

I do not believe so . Code p0715 if that relates to your question refers to the turbine shaft speed(TSS) sensor-circuit malfunction===causes wiring--TSS sensor--ECM/TCM
The drive speed sensor is the sensor that works the speedo and sends impulses to the transmission control module to change gears in relation to the turbine speed sensor
This is how the TCM knows when to change ratios in the transmission because of the differences in recorded speeds of the engine torque convertor and the drive shaft

What is P0715 code for a 2002 Ford Explorer Sport?


If it's EOBD code, it means transmission turbines speed sensor error.Could be wiring to the TCM. transmission control module. View life data of the transmission. There should two speed data(usually in rpm), one is input from engine and the other the transmission shaft speed.

Now i dont know a lot about automatics especially modern ones with all this fancy electronics thats used nowdays but i think its a fault with the temperature sensor for the gearbox.But where its located and what it looks like i have no idea it could even be mounted inside the gearbox .Sorry not a very good answer from a mechanic but?? very few of our europeon cars come with auto transmission .Evan when i do know whats wrong i cannot buy the parts for the gearbox as only re-con boxes supplied by the dealer so best advice is to try a specialist in auto box repairs only .PS some of my best students when i used to teach mechanics many moons ago were the girls so no excuses like iam only a girl please

P0722 FAULT CODE


P0722: Transmission speed signal missing.

There is a turbine speed sensor that detects and reports the speed of the transmission shaft to the computer to help determine shift points. Sometimes this duty is shared by the VSS (vehicle speed sensor) but if your speedometer still works, then the VSS is good and you should replace the TSS (turbine speed sensor). I would guess you are either stuck in 1st gear all the time or your transmission shifts erratically.

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.
