    Help!!!!!!

    gotta a mk4 astra convertible 1.8 z18xe, the car with spanner light will not go out, i had the diaogostic on it and the fault is... error code p1555
    throttle position sensor load signal not plausible with engine load.
    so ive checked the throttle body out, ive cleaned it but no luck.

    also error p0170 which is exhuast lean. ive been told this could be the maf but i have a maf in my room lucky enough.

    how can i sort this throttle body out, or is a sensor of some sort i relly dunno. and vauxhual charge you a bomb!

    you need to look at the pedal sensor and check this out first, if this is ok then the throttle body itself will be at fault and they cannot be repaired as they are a sealed unit.

    p0170 is fuel trim bank 1 malfunction. causes intake leak,air system,fuel pressure/pump ,injectors,evap canister purge valve ho2s. thats whats come up with the engine code z18xe. i would start looking for a air leak around the intake pipes and around the trottle body
