Drivable short-term, but fix now to avoid damage.
This code indicates the transmission range sensor circuit is sending a signal voltage that's too low, often caused by a short to ground or an open in the wiring. Since this sensor tells the computer your shifter position, a low signal can lead to wrong-gear engagement or starting problems. Typical repairs include fixing shorted or open wiring, cleaning connectors, or replacing the range sensor.
$150 – $500
Varies by vehicle and root cause.
It's best to limit driving. A low sensor signal can cause the transmission to shift incorrectly or the car not to start, so have it diagnosed before relying on the vehicle.
If it's a wiring or connector fix, you may spend $100 to $250. A full range sensor replacement with diagnosis can run $300 to $500.
Yes, it can be. It affects gear selection and starting, both of which are safety-related, so prompt repair is recommended.
Low input means the sensor's signal voltage dropped below the expected level, usually due to a short to ground or a broken wire. The computer flags this because it can't trust the gear position reading.
