    E8A high pressure fuel line

    In PCM E80A, the fuel pressure is controlled in relation to the air volume measured by the maf sensor, ok.

    Is there any other parameter that can make the high pump pressure decrease?
    On the map it is 20,000 kpa but in the log it is 1,000 kpa.
    The low pressure line is always at the pressure determined on the map

    Can someone help me?

    Hello, my problem was the high pressure pump. The car was zero km but I changed it and solved it.
