Eml fault codes on lpg
Hi I have just got my v70 and when it runs on lpg the eml is on and I get the attached fault codes, is this normal or is there anything I need to do?
P0088 fuel rail system pressure too high P0090 fuel pressure regulator 1 control circuit The system is a Romano multi point injection system and linked to the obd |
The reason for the fault is that this age car needs a return line fitting on the petrol rail to keep the petrol pressure correct.

there is a take off valve under the car. You need to run a pipe from that to the sender unit or filler neck with a solenoid powered by the LPG power cable. The flow needs calibrating to simulate normal petrol flow.

If I just leave it as is would it cause any problems? |
Left as is the fuel mixture will never be right as the fuel pressure is part of the fuel table
