The cost to diagnose the P0001 Mercury code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.
The Fuel Volume Regulator is a solenoid valve permanently mounted to the pump assembly. The Powertrain Control Module (PCM) commands the Fuel Volume Regulator to meter in a specified fuel volume with each pump stroke. The PCM regulates the fuel volume entering the rail to achieve the desired fuel rail pressure.
The Fuel Volume Regulator control is synchronous with the cam position on which the pump is mounted. The Fuel Volume Regulator control takes into account that camshaft phasing varies during engine operation for purposes of valve control.
This Diagnostic Trouble Code (DTC) sets when the Powertrain Control Module (PCM) detects high or low voltage on the Fuel Volume Regulator (FVR) and Fuel Volume Regulator Return (FVRRTN) circuits.
