Code P027A Description

The Powertrain Control Module (PCM) monitors the Fuel Pump Command (FPC) circuit for a concern.

When the PCM commands the FP OFF, the PCM is able to detect an open circuit or a short to ground on the FPC circuit. The test fails if the voltage is less than or greater than a calibrated limit, for a calibrated amount of time.
