    Z20let fault codes help

    hi im new here and wondering if anyone can help me with some fault codes that my car has stored, its a 2001 astra coupe turbo and haas 3 codes stored
    1106
    0170
    0136

    The problem seems to be car hesitates a bit when applying power as though its not boosting correctly.

    the car did have a spanner light up which stayed on but yesterday it went off for a few journeys and then came back on, later last night the spanner light has now been replaced by the emissions light which im a bit worried about. Ive done a search and found that the 1106 code could be a bad earth but i would like to know what the codes mean so i can have an idea where else to look, i cant book into vaux until thursday so gonna try and do it myself.

    cheers

    the spanner light has come back on after a drive. Boost pressure control device malfunction, which sensor is this, is it the one that sits on top of the intercooler?
