B0516 Buick Code - Speedometer Signal Circuit Malfunction
Quick Answer
The Instrument Panel Cluster (IPC) receives vehicle speed information from the Powertrain Control Module (PCM). Common causes include Faulty Instrument Panel Cluster (IPC), Instrument Panel Cluster (IPC) harness is open or shorted, Instrument Panel Cluster (IPC) circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
