    Mk3 Astra can't read fault codes

    Just did the head gasket on a mk3 Astra 1.4 DOHC P reg X14XE I think. Fault code light is on and stays on, when try to read codes - done before - light just stays on. Runs OK, not so smooth on overrun. Anyone know what is happening? Jon

    join pips a+b on the aldl plug together then ign on, the light will blink the codes out to you, cant remember the exact sequence offhand but it is a start code 3 times, then all the stored codes 3 times then the start code 3 times again to finish
    Be Happy

    Sorry, the point is that I know how to read fault codes and have done it before - but now if I connect the correct points on the connector in the fuse box, the light stays stubbornly on. Therefore I think something is wrong - any suggestions please. Thanks.

    Got it now, wasn't using correct pins to read out codes - hadn't connected TPS all sorted and well. Thanks anyway.
