P0715 on Lincoln
Input/Turbine Speed Sensor Circuit Malfunction
P0715 on Lincoln vehicles indicates input/turbine speed sensor circuit malfunction. Au7o has documented this code across 1 Lincoln model — most commonly on Aviator. 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.
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 Lincoln by Model
Lincoln Aviator(1 issue)
- 10R80 Automatic Transmission Loose Bolt / Park Failure2022-2025
The Ford 10R80 10-speed automatic transmission used in the Aviator can have a loose or missing park pawl/output bolt that prevents the transmission from securely engaging Park. If the vehicle is not held by Park, it can roll away even with the shifter in Park, creating a crash and injury risk. This was serious enough to trigger a federal recall covering 2022-2023 Aviators, and a separate 2025 recall addressed incorrect main control valve bodies causing reverse-gear failure or unexpected forward movement.
