P0715 on Nissan
Input/Turbine Speed Sensor Circuit Malfunction
P0715 on Nissan vehicles indicates input/turbine speed sensor circuit malfunction. Au7o has documented this code across 1 Nissan model — most commonly on Armada. 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 Nissan range from $150 to $4,000, 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 Nissan by Model
Nissan Armada(1 issue)
- RE7R01A 7-Speed Shift Shock, RPM Fluctuation and Light-Throttle Hesitation (Y62)2017-2020
The Y62 Armada's JATCO RE7R01A seven-speed draws a cluster of driveability complaints: a shock on 7-to-3 downshifts, engine RPM wandering at steady cruise, hesitation and a flat spot under light acceleration from low speed, and early upshifts into 3rd around 18-20 mph. Nissan addressed the driveability half with a TCM/ECM reprogram (bulletin NTB17-016, later revised) covering the 2017 Armada, Titan and Titan XD. Where a reflash does not settle it, the mechanical cause on this unit is bore and sleeve wear in the valve body - the low brake switch boost sleeve and the pilot valve bore in particular - which produces delayed engagement and harsh 4-3 downshifts as pressure leaks past.
