Vehicle Buffered Power (VBPWR)
WARNING: This page is about a different variant/trim than selected.
The VBPWR is a regulated voltage supplied by the PCM to vehicle sensors. These sensors require a constant 12 volts for operation and cannot withstand VPWR voltage variations. The VBPWR is regulated to VPWR minus 1.5 volts and is also current limited to protect the sensors.
