P2687: Your Engine’s Fuel System Is In Trouble
The P2687 code refers to the fuel heater relay control circuit. Ignition voltage is supplied to the coil side of the fuel heater relay when the ignition is On. The Engine Control Module (ECM) controls the fuel heater relay by providing a ground.
The voltage of the control circuit should be low when the ECM commands the fuel heater On. The voltage of the control circuit should be high when the ECM commands the fuel heater Off. The DTC will be set when the ECM detects an open fuel heater relay control circuit for more than 1 second.
