    Default Landcruiser 79 pickup 1gr fe problem p0102

    My landcruiser shows p0102 (mass airflow ciruit low) on diagnostics
    i replaced the maf sensor and airfilter.
    i checked fuses all fine.

    The cruiser stays in limp mode.

    Now i want to start by checking relays and wiring.
    where can i find a diagram that shows me what relay is where and for what.

    how can i resolve this problem. Any advise.

    Have you disconnected the battery for 10 minutes yet? this is to clear the fault and see if it returns after that.

    It is not what you buy its what you build.

    mass airflow ciruit low


    The ECU does 'n continuity check on the circuit and the OHM (resistance) value is not within the tolerance range. Either your new MAF sensor is the wrong type or faulty or the wiring at the plug or in between is cut and open circuit.

    The trouble code points you towards the problem. To clear the trouble code disconnect battery for 2min. It will still be logged in the ECU as a old code until cleared with TechStream, but it won't keep the vehicle in limp mode.
