    Hi guys,
    I am trying to find out what the normal values are for my maf sensor at idle. Car is a 2006 Toyota Corolla with 1ND-TV engine, 1.4D4D.
    Also What should the value be under load.
    At idle it is currently reading at 6.69 g/s.
    Thanks

    Whoopsies thinking of another type of maf.

    Those are found on a range of different engines and are commonly asked for. Try another one, it could be fooked

    Roughly £40 second hand

    Your fathers car would seem to be correct with no egr and slight boost.

    Your own may also be correct allowing for egr, depends on the conditions.

    When the boost is factored in the values will change (google volumetric efficenty)

    Different scantools give the flow rate at different scales. Yours is g/s some are mg/s.

    Most good scan tools will show actual flow and desired flow to compare. Even if the figures are wrong it doesent mean the

    flowmeter is at fault, it may be a leak or faulty egr valve.

    Is there a problem.

    This was both at idle, both using the same tool, same location and both checked by me.
    Anyways aside from that I did discover that I have a boost leak in my car. Is it safe to put soapy water on all all related hoses, rev and check for bubbles?
    Thanks
