Drive with caution — fix soon.
This code means the vehicle speed sensor signal is intermittent, erratic, or reading too high compared to actual vehicle speed. It often points to loose or corroded connectors, damaged wiring, a failing speed sensor, or electrical interference. It's usually a repairable issue handled by tightening connections, repairing wiring, or replacing the sensor.
$110 – $400
Varies by vehicle and root cause.
Usually yes, but be cautious. The speedometer may jump or spike and cruise control can cut out unexpectedly, which affects safety. It generally won't strand you, but get it checked soon to avoid surprises.
Most repairs run $110 to $400. Tightening or cleaning a connector can be cheap, while replacing the sensor or repairing chafed wiring costs more. Because the fault is intermittent, diagnosis time may be needed to catch it.
It's moderately serious. The car runs, but erratic speed readings affect the speedometer, cruise control, and shifting, which carry safety concerns. Address it soon, especially since intermittent faults can worsen over time.
Erratic or high readings usually come from a loose connector, chafed wiring, or electrical interference that disrupts the sensor signal. Because it's intermittent, the problem can come and go, so a careful inspection of the connector and wiring is often the key to fixing it.
