Fuel Volume Regulator Control Circuit/Open

The Powertrain Control Module (PCM) monitors the Fuel Volume Regulator (FVR) and Fuel Volume Regulator Return (FVRRTN) circuits to the PCM for high and low voltage.

Faulty Fuel Volume Regulator (FVR) Control Solenoid
Fuel Volume Regulator (FVR) Solenoid harness is open or shorted
Fuel Volume Regulator (FVR) Solenoid circuit poor electrical connection

Check engine light

Possible Solution:
First, check for known Technical Service Bulletins (TSBs) for your year/make/model. If there is a known TSB that addresses this issue, it can save you time & money during diagnosis. Next, you'll want to visually inspect the wiring and connectors pertaining to the fuel volume regulator circuit and system. Look for obvious breaks in the wires, corrosion, etc. Repair as necessary. The fuel volume regulator (FVR) is a two-wire device with the wires both going back to the PCM. You should not apply direct battery voltage to the wires or you could damage the system.
