Drivable short-term, but fix now to avoid damage.
This code means the transmission range sensor circuit is sending a signal voltage that's too high, often due to a short to power or a high-resistance connection. Because the sensor reports your shifter position, a high signal can confuse the computer about which gear is selected. Typical repairs involve fixing the wiring or connectors and, if needed, replacing the range sensor.

Varies by vehicle and root cause.
It's best to limit driving. A high sensor signal can cause incorrect shifting or starting problems, so have it diagnosed before depending on the car.
Wiring or connector repairs may cost $100 to $250. Replacing the range sensor with diagnosis typically runs $300 to $500.
Yes. Like other range sensor codes, it affects gear selection and starting, which are safety concerns, so it should be addressed promptly.
High input means the sensor's signal voltage climbed above the normal range, usually from a short to power or a corroded, high-resistance connection. The computer can't trust the gear reading and sets the code.
