P0715 on Jeep
Input/Turbine Speed Sensor Circuit Malfunction
P0715 on Jeep vehicles indicates input/turbine speed sensor circuit malfunction. Au7o has documented this code across 1 Jeep model — most commonly on Grand Cherokee. P0715 indicates a malfunction in the input/turbine speed sensor circuit of an automatic transmission. This sensor measures how fast the transmission's input (turbine) shaft is rotating, which the transmission control module uses—alongside output speed—to calculate gear ratios and command smooth, properly timed shifts. When the signal is missing, erratic, or out of range, this code sets. Symptoms often include harsh or erratic shifting, incorrect shift points, no speedometer-related transmission data, or the transmission dropping into a limp/fail-safe mode. Typical repair costs on Jeep range from $300 to $3,500, depending on the specific model and root cause.
Common Causes of P0715
- •Faulty input/turbine speed sensor
- •Damaged wiring or connector at the sensor
- •Low or contaminated transmission fluid
- •Corroded or loose connector terminals
- •Open or short in the sensor circuit
- •Internal transmission wear or debris affecting the sensor
- •Faulty transmission control module (less common)
P0715 on Jeep by Model
Jeep Grand Cherokee(1 issue)
- W5A580 (NAG1) 5-Speed Automatic Limp Mode and Harsh Shift from Conductor-Plate Speed Sensors and Fluid Contamination2005-2013
The Mercedes-derived W5A580 (NAG1) 5-speed automatic used in WK and early WK2 Grand Cherokees is mechanically strong but suffers well-documented electronic and fluid-related failures. Faulty conductor-plate speed sensors and shift-pressure solenoids drop the transmission into limp mode (stuck in a single gear). Contaminated or degraded fluid (including water intrusion past the dipstick/fill-tube seal) causes torque-converter-clutch shudder, harsh or delayed shifts, and a knock on coasting downshifts. The 13-pin connector adapter can also leak, wicking fluid into the harness by capillary action.

What does P0715 mean on Jeep?▼
P0715 stands for "Input/Turbine Speed Sensor Circuit Malfunction." P0715 indicates a malfunction in the input/turbine speed sensor circuit of an automatic transmission. This sensor measures how fast the transmission's input (turbine) shaft is rotating, which the transmission control module uses—alongside output speed—to calculate gear ratios and command smooth, properly timed shifts. When the signal is missing, erratic, or out of range, this code sets. Symptoms often include harsh or erratic shifting, incorrect shift points, no speedometer-related transmission data, or the transmission dropping into a limp/fail-safe mode. On Jeep specifically, this code is documented across 1 model.
