P025C-11 Fuel Pump Control Module-Circuit Low

In Jaguar F-Pace fault code P025C-11 Fuel Pump Control Module-Circuit Low is related to the problem with fuel pump control module relay. In Jaguar there is a fuel pump control module, which is use to drive fuel pump. If there is any problem occurs with fuel pump control module relay. Vehicle will crank but it will no start. If in case fuel pump is working fine and diesel is coming out from fuel pump when ignition is turn ON. Then also vehicle will not start, due to no function of high pressure fuel pump which is fitted at engine. Because this fuel pump control module relay also control high pressure pump control valve. If control valve will not open then fuel will not reach at fuel rail. If fuel will not reach at rail then there will be no start. When this all things happen fault code P025C-11 Fuel Pump Control Module-Circuit Low will store in engine control module.

Causes of P025C-11 Fuel Pump Control Module-Circuit Low :

  • Faulty fuel pump control module.
  • Faulty fuel pump.
  • Blown fuse.
  • Faulty primary relay at rear fuse box.
  • Damage wiring harness.

Symptoms of P025C-11 Fuel Pump Control Module-Circuit Low :

  • Vehicle will only crank, there will be no start.
  • Fuel pump will not work.
  • Fuel will not reach to fuel rail.
  • Fault code will store im control module.

How to trouble shoot :

  • Whenever found fault code P025C-11 Fuel Pump Control Module-Circuit Low mechanic need to start checking fuel supply system. Start checking fuel supply system from fuel pump. Go through pipe line of fuel pump till fuel injector of fuel is reaching or not.
rear right fuse box
  • CASE#1 First remove rear seat and then remove cover of fuel pump. Disconnect socket of fuel pump and connect multimeter on both pin of fuel pump socket. Turn ignition on if there is 12Volt after ignition then it is good. If there is no 12Volt after ignition then go to rear side fuse box there is a relay and 5Amp fuse check both of them. If fuse is blown then replace that fuse with new one and if relay is faulty than replace it with new one.
  • CASE #2 If there is 12Volt present on the socket of fuel pump than fuel pump must be ON when ignition is turn ON. Remove pipe of fue pump and then turn ON ignition fuel must be coming out. If fuel is not coming out from fuel pump than it means fuel pump is not working. Replace fuel pump with new one so that the problem can be solve.
  • If fuel is coming out and it must be in pressure like if you are placing your one finger on the top of pipe you should feel pressure if fuel coming out.
  • When fuel is coming out than go to check fuel at fuel filter. From fuel filter fuel should coming out in presure, near fuel filter there is a fuel heater. Check that fuel heater if fuel is coming out from it in high pressure.

  • Than go to check fuel presure at fuel rail from where fuel go to injector.
  • Fuel must be coming out in pressure from high pressure pump.

Case #3:

  • If fuel is coming out from fuel pump and reaching till high pressure fuel pump, and from fuel high pressure pump fuel is not coming out. Than it is clearly indicate that fuel pump control module is faulty.
  • Because in Jaguar F-Pace fuel pump Control module also control high pressure pump switch (control valve). So if fuel pump control module is not working than there will be no fuel coming out from high pressure fuel pump.
  • In this situation replacing fuel pump is a good idea to solve problem.

Solution :

  • Replace faulty fuel pump relay control module.
  • Replace blown fuse.
  • Repair damage wiring harness.
  • Replace faulty fuel pump.
  • Repair or replace damage fuel pipe.

Special note :

Whenever found fault code P025C-11 Fuel Pump Control Module-Circuit Low in jaguar xf, xjl, f pace, f type etc. Replacing fuel pump and fuel pump control module relay is a good idea. As when there is a problem of faulty relay occurs at fuel supply system, and someone try to start vehicle by cranking again and again. Due to cranking again and again fuel pump get so weak. Thats why after replacing fuel pump control module vehicle will start but there will be a problem of fuel pump.

Thats why replacing fuel pump along with fuel pump control module is a good thing so that there is no problem or fault code appear in system.
