DESCRIPTION

This DTC is stored when the combination meter assembly detects a fuel sender gauge assembly malfunction via a direct line.

FOR 2WD

The fuel sender gauge assembly is connected to the combination meter assembly via direct line. If there is an open or short in the direct line, the combination meter assembly stores DTC B150013.

FOR AWD

The fuel sender gauge assembly and No. 2 fuel sender gauge assembly are connected to the combination meter assembly via direct line. If there is an open or short in the direct line, the combination meter assembly stores DTC B150013 or B150113.
