P0716 on Pontiac
Input/Turbine Speed Sensor "A" Circuit Range/Performance
P0716 on Pontiac vehicles indicates input/turbine speed sensor "a" circuit range/performance. Au7o has documented this code across 1 Pontiac model — most commonly on Bonneville. This code means the input/turbine speed sensor is producing a reading that is out of the expected range or is inconsistent with other data. This sensor tells the transmission control module how fast the transmission input shaft (turbine) is turning, which is used to calculate gear ratios and time shifts. An erratic or out-of-range signal can cause harsh shifting, incorrect shift timing, or the transmission entering limp mode. It is often caused by sensor, wiring, or fluid issues. Typical repair costs on Pontiac range from $200 to $1,800, depending on the specific model and root cause.
Common Causes of P0716
- •Faulty input/turbine speed sensor
- •Low or dirty transmission fluid
- •Damaged sensor wiring or connector
- •Metal debris on the sensor tip
- •Internal transmission wear affecting the signal
- •Faulty transmission control module

- GXP 4T80E Torque Converter Internal Seal Failure and TCC Shudder (with Input Speed Sensor Failure)2004-2005
Behind the Northstar, the 2004-2005 GXP uses the Cadillac 4T80E. Owners in GM Forum's GXP section report the second most common GXP failure after head gaskets: an internal torque converter seal that shrinks or tears, producing a rumble-strip shudder at light throttle around 35-45 mph in 4th with the converter clutch applied, temporarily relieved by a light brake-pedal touch or cancelling overdrive. Left alone the converter clutch burns and the transmission starts slipping. The 4T80E input speed sensor is also a frequent failure that sets P0716/P0717 and forces limp mode; because it sits inside the case, it is normally replaced during the converter job. GM issued a bulletin on a 4T80E torque converter design change for 2005 DeVille and Bonneville.

What does P0716 mean on Pontiac?▼
P0716 stands for "Input/Turbine Speed Sensor "A" Circuit Range/Performance." This code means the input/turbine speed sensor is producing a reading that is out of the expected range or is inconsistent with other data. This sensor tells the transmission control module how fast the transmission input shaft (turbine) is turning, which is used to calculate gear ratios and time shifts. An erratic or out-of-range signal can cause harsh shifting, incorrect shift timing, or the transmission entering limp mode. It is often caused by sensor, wiring, or fluid issues. On Pontiac specifically, this code is documented across 1 model.
