P0715 on Hyundai
Input/Turbine Speed Sensor Circuit Malfunction
P0715 on Hyundai vehicles indicates input/turbine speed sensor circuit malfunction. Au7o has documented this code across 1 Hyundai model — most commonly on Elantra. 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 Hyundai range from $150 to $450, 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)

- Automatic Transmission Input/Output Speed Sensor Failure Causing Harsh Shifting2001-2006
Owners of automatic-transmission Elantras from this generation frequently report sudden harsh shifts, incorrect gear selection, limp mode, or a stuck speedometer caused by failing transmission speed sensors. Hyundai service literature and repair databases commonly reference input and output speed sensor faults on these vehicles. The problem often appears intermittently at first, then becomes more consistent as the sensor signal drops out.
