In some rare cases, the only symptom will be the Check Engine light, but in most instances one or more of these symptoms will occur. The engine will seem to misfire when coming to a stop after traveling at higher speeds.The vehicle will not shift as expected and may have hard, sudden, or delayed shifts.When the P0717 code is stored, a number of symptoms will occur: A faulty engine coolant temperature sensor.A shorted, open, or otherwise damaged circuit. What causes the P0717 code?Ī few common causes can result in a P0717 code, including: When the PCM does not get the expected input signal from the input/turbine speed sensor, it cannot make the proper predictions or matches to deliver a good shifting strategy. What the P0717 code meansĪn automatic transmission is designed to match the vehicle’s engine’s best torque and power characteristics to match the driver’s acceleration or deceleration pattern. In any of these cases, the PCM will record the code and turn on the Check Engine light. This signal may be interrupted briefly, or it may be erratic or otherwise outside of expected manufacturer settings. The PCM (powertrain control module) will set the P0717 code when it detects no signal from the input/turbine speed sensor.
