P0717: No signal from the transmission input or turbine speed sensor
Input/turbine speed sensor no signal
Severity: Inspect soon
Toyota tells owners to have the car inspected right away when the check engine light comes on for the automatic transmission, and bulletins pair this code with lack of power or missing gears on some Fords and GMs.
It gets more serious if:
- Not verified: The transmission goes into limp-home mode (stuck in one gear, little power) or will not shift. Regulations require the light in limp-home mode, but we found no source saying whether you must stop
P0717 in short
P0717 means the transmission computer gets no signal from the input or turbine shaft speed sensor. A failed sensor or wiring is common, but some bulletins trace it to clutch damage inside the transmission. Have it inspected soon, and check for a bulletin before replacing parts.
The input or turbine speed sensor reads how fast the shaft coming out of the torque converter turns. The computer compares it with engine and output speed to judge converter slip and confirm each gear. P0717 sets when it expects pulses from this sensor and gets none.
Often the sensor or its circuit has failed. Ford replaces the turbine shaft speed sensor on some 2020 Super Duty trucks, and GM checks a circuit at the transmission connector on some 2013 trucks and vans.
The code can also come from damage inside the transmission. On some 2016 GM crossovers and sedans and some 2015–2016 Ford 6F transmissions, a failed clutch assembly breaks the sensor reading and the car loses reverse and some forward gears. A bulletin check by VIN comes first.
Most likely causes
Cause 1: Faulty input/turbine speed sensor, connector or wiring
Common general cause- Why it ranks here
- A dead sensor or open circuit gives no signal, and Ford replaces this sensor for P0717 on some Super Duty trucks.
- What would change this
- Rises if the reading stays at zero on a scan tool while the engine runs in gear, or wiring damage is found.
Cause 2: Sensor circuit fault at the transmission connector (2013 GM trucks and vans)
Supported by vehicle data- Why it ranks here
- GM tells technicians to check circuit 1984 at the 20-way transmission connector for P0716 or P0717 with harsh shifts.
- What would change this
- Rises on a 2013 Silverado, Sierra, Express or Savana with harsh shifts.
Cause 3: Internal clutch damage disturbing the sensor reading (2016 GM, 2015–2016 Ford 6F)
Supported by vehicle data- Why it ranks here
- GM and Ford bulletins pair P0717 with no reverse and missing gears and fix it inside the transmission, not at the sensor.
- What would change this
- Rises if reverse, third or fifth gear is missing.
Cause 4: Transmission computer reporting error (2008 Caliber, Compass, Patriot)
Supported by vehicle data- Why it ranks here
- Chrysler issued a software flash because these vehicles could report the wrong code for an input speed fault.
- What would change this
- Rises on a covered 2008 Dodge or Jeep that has not had the flash.
What to test first
Start at step 1. Each result tells you what it means and where to go next.
Step 1: Read codes from the engine and transmission modules with a scan tool that supports both, before anything is cleared.
IfOther speed sensor codes are stored too
It meansCheck for a bulletin; several cover groups of speed sensor codes.
IfP0717 alone
It meansCheck for a bulletin.
Step 2: Check for a P0717 bulletin for your VIN at a dealer or on the NHTSA site.
IfA 2020 Ford Super Duty with the 10R140 built by 21 Sep 2020
It meansFord replaces the turbine shaft speed sensor.
Points to: Faulty input/turbine speed sensor, connector or wiring
IfA 2013 GM full-size truck or van
It meansGM checks circuit 1984 first.
Points to: Sensor circuit fault at the transmission connector (2013 GM trucks and vans)
IfA 2016 GM crossover or sedan, or a 2015–2016 Ford with the 6F50/6F55, with no reverse
It meansThe repair is inside the transmission.
Points to: Internal clutch damage disturbing the sensor reading (2016 GM, 2015–2016 Ford 6F)
IfA 2008 Caliber, Compass or Patriot
It meansChrysler has a software flash.
Points to: Transmission computer reporting error (2008 Caliber, Compass, Patriot)
IfNo bulletin applies
It meansA shop needs to test the sensor circuit.
Step 3: Have a shop watch the input speed reading on a scan tool in gear, then test the sensor connector and wiring.
Warning:Shop test. The vehicle must be in gear with the engine running, and wiring checks follow the maker's procedure.
IfNo input speed reading with the engine running in gear
It meansThe sensor or its circuit is at fault.
Points to: Faulty input/turbine speed sensor, connector or wiring
IfThe reading is normal but gears are missing
It meansLook inside the transmission.
Points to: Internal clutch damage disturbing the sensor reading (2016 GM, 2015–2016 Ford 6F)
Symptoms
- Check engine light, sometimes with a wrench light on Fords
- Harsh shifts
- Lack of power on some Ford Super Duty trucks
- No reverse, third or fifth gear on some GM and Ford models Gets more serious: stop and have it checked.
- Transmission stuck in one gear or reduced power (limp-home mode) Gets more serious: stop and have it checked.
Compare with: Check engine light with loss of power
How to fix
Step 1: Do not clear the code before the transmission module has been read.
Step 2: Ask a dealer whether your VIN has an open P0717 bulletin. Ford, GM, Hyundai and Chrysler have issued them.
Parts and cost context
- Transmission control module (TCM):Do not replace the transmission computer for P0717 unless a test points to it. Hyundai warns against replacing the transmission for its speed sensor codes, and most fixes are the sensor, its wiring or internal clutch parts.

P0717 questions
Is P0717 just a bad sensor?
Often, but not always. Some GM and Ford bulletins trace it to clutch damage inside the transmission, especially when reverse or some gears are missing. Check for a bulletin before buying a sensor.
