B0516 CHEVROLET Possible Causes

 

Faulty Instrument Panel Cluster (IPC),Instrument Panel Cluster (IPC) harness is open or shorted,Instrument Panel Cluster (IPC) circuit poor electrical connection

 

B0516 CHEVROLET Description

 

The Instrument Panel Cluster (IPC) receives vehicle speed information from the Powertrain Control Module (PCM). IPC receives a 4000 pulse-per mile Vehicle Speed Sensor (VSS) input over a dedicated circuit from PCM. PCM is responsible for processing and sending VSS data to IPC. IPC monitors VSS output information sent from PCM for an out of range condition.
