OBD-II (EN): Transmission Range Sensor Circuit Malfunction

Code P1715 indicates an abnormality in the transmission range sensor circuit or pulse generator – components crucial for proper automatic transmission operation. It manifests as problems with gear shifting, limp mode, or loss of drive. Due to the complexity of the drivetrain, professional diagnostics with an OBD-II scanner and multimeter are recommended before proceeding with repairs.

Symptoms

Incorrect or hard gear shifts Transmission operating in limp mode No response to range selection (P/R/N/D) Transmission slippage or loss of drive MIL (Check Engine) light illuminated Problems with moving the vehicle Incorrect range indication on the dashboard

Possible causes

Damaged or worn transmission range sensor (PRNDL/TRS) Damaged wiring or electrical connectors leading to the sensor Faulty Pulse Generator Assembly inside the transmission Mechanical damage to internal transmission components (e.g., worn drum splines) Damaged transmission control module (TCM) Low level or contaminated ATF transmission fluid Problems with the reluctor ring or crankshaft speed sensor (in Nissan models)
