    Lightbulb All four o2 sensors heating issue in M54B25.

    I recently bought a car. The check engine lights up. Inpa shows errors of heating for all four lambda probes! I checked the fuses in the ECU box, they are good ...

    Error codes:

    79
    61
    25
    55

    Also some missfire codes (i think cause by probes).

    Screens:



    Any ideas?

    Thanks!

    Hi,

    No, only unleaded gas. In Poland leaded gas is no longer available i think.

    My car has LPG installations if that's important.

    Where do the wires from lambda sensors come into power? Under the car?
