P0705 on Genesis
Transmission Range Sensor Circuit Malfunction (PRNDL Input)
P0705 on Genesis vehicles indicates transmission range sensor circuit malfunction (prndl input). Au7o has documented this code across 1 Genesis model — most commonly on GV70. The transmission range sensor (also called the neutral safety switch or PRNDL switch) tells the computer which gear position the shifter is in (Park, Reverse, Neutral, Drive). P0705 sets when the signal from this sensor is missing, out of range, or inconsistent. Symptoms include no-start in Park, the wrong gear indicator on the dash, harsh or incorrect shifts, and sometimes the engine starting in any gear position.
Common Causes of P0705
- •Faulty transmission range / neutral safety switch
- •Misadjusted shift linkage or range sensor
- •Damaged or corroded wiring and connectors
- •Poor ground connection
- •Failed PCM or TCM

- Transmission Harness Water Leak Causing Park-to-Neutral Rollaway2024
Blanking pins were incorrectly installed in the transmission control harness connectors at the supplier, allowing water to enter the connectors and cause an electrical short. The short can make the transmission controls erroneously and unexpectedly shift from Park to Neutral, allowing the vehicle to roll away if the parking brake is not set. Genesis recall 020G (NHTSA 24V-205) covers roughly 15,645 GV70 built May 10, 2023 to Feb 25, 2024.
