Drivable short-term, but fix now to avoid damage.
This code is set when the transmission range sensor signal cuts in and out intermittently rather than failing completely. The on-and-off nature usually points to a loose connection, chafed wiring, or a sensor that's beginning to fail. Diagnosis involves wiggle-testing connectors and harnesses to find the intermittent fault, then repairing wiring or replacing the range sensor.
$150 – $500
Varies by vehicle and root cause.
Short-term driving is often possible, but be cautious. Intermittent faults can cause sudden shifting surprises and tend to get worse, so have it diagnosed soon.
Tracking down and repairing an intermittent wiring fault may cost $100 to $300 in labor. If the range sensor needs replacing, expect $300 to $500 total.
It can be. Even though it's intermittent, it affects gear selection and starting, and intermittent issues often progress into constant ones. It's worth addressing before it worsens.
Because the fault isn't present all the time, it can be tricky to catch during testing. Mechanics often wiggle wiring and connectors or use data logging to reproduce the dropout and pinpoint the cause.
