Code U016C Lincoln Description

The Powertrain Control Module (PCM) monitors the Fuel Pump Monitor 2 (FPM2) circuit for the presence of a duty cycled signal. If the FPM2 circuit is fixed at a low or high voltage, the PCM begins to increment a counter. The test fails when the PCM is still not detecting a duty cycled signal on the FPM2 circuit after a calibrated amount of time.
