P0717 on Pontiac
Input/Turbine Speed Sensor Circuit No Signal
P0717 on Pontiac vehicles indicates input/turbine speed sensor circuit no signal. Au7o has documented this code across 1 Pontiac model — most commonly on Aztek. This transmission code means the computer is receiving no signal from the input/turbine speed sensor, which measures how fast the transmission's input shaft (turbine side of the torque converter) is spinning. The computer compares this against engine and output speeds to control shifts and torque converter lockup. With no signal, it can't manage shifting properly, so you may get harsh or erratic shifts, no torque converter lockup, or limp mode. It is a no-signal electrical fault pointing to the sensor or its circuit. Typical repair costs on Pontiac range from $800 to $4,500, depending on the specific model and root cause.
Common Causes of P0717
- •Failed input/turbine speed sensor
- •Open or shorted wiring to the sensor
- •Corroded or loose sensor connector
- •Damaged reluctor/tone ring on the input shaft
- •Metal debris on the sensor tip from internal wear
- •Poor ground or reference voltage to the sensor
- •Faulty transmission control module (less common)
P0717 on Pontiac by Model
Pontiac Aztek(1 issue)
- 4T65-E Transmission Failure and Pressure Control Solenoid Erratic Shifting2001-2005
The Aztek's 4T65-E four-speed automatic suffers from pressure control (force motor) solenoid failure that drives line pressure to maximum, causing harsh shifting and accelerating internal wear; GM addressed related harsh-shift complaints in TSB 02-07-30-022B (faulty transaxle connectors, 2001-2004) and cold-weather reverse servo seal shrinkage in TSB 04-07-30-028. NHTSA complaints for the 2003 Aztek document gear failure, no-forward-movement, and shifter problems at an average of about 157,000 miles. Left unaddressed, the harsh-shift condition commonly progresses to slipping and loss of 3rd/4th gear requiring a rebuild or replacement.

What does P0717 mean on Pontiac?▼
P0717 stands for "Input/Turbine Speed Sensor Circuit No Signal." This transmission code means the computer is receiving no signal from the input/turbine speed sensor, which measures how fast the transmission's input shaft (turbine side of the torque converter) is spinning. The computer compares this against engine and output speeds to control shifts and torque converter lockup. With no signal, it can't manage shifting properly, so you may get harsh or erratic shifts, no torque converter lockup, or limp mode. It is a no-signal electrical fault pointing to the sensor or its circuit. On Pontiac specifically, this code is documented across 1 model.
