DTC B0516: Speedometer Signal Circuit Malfunction: Description

WARNING: This page is about a different car, the 2000 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

Powertrain Control Module (PCM) supplies Instrument Panel Cluster (IPC) with information on vehicle speed. PCM processes information from Vehicle Speed Sensor (VSS), and sends a 4000 pulse-per-mile input to IPC.

DTC B0516 will set when IPC detects vehicle speed information over 200 MPH (322 KM/H) for one second. IPC will display vehicle speed at 200 MPH (322 KM/H). No driver warning message will be displayed.

If conditions for malfunction no longer exist, history DTC will clear after 50 consecutive ignition cycles. DTC B0516 will also clear when conditions no longer exist, or when IPC or scan tool is used to clear codes.

NOTE: If DTC B0516 is a history code, problem may be intermittent. Wiggle wires while performing the following test.
