i brought my car with a few minor fault's (only expected as it's done 213k miles) but the one that is doing my head in is the throttle possition sensor low voltage fault i cant seem to get around....the car is a facelift W reg 2.2 estate with lpg and i have replaced the following
throttle pedal
throttle body
cleaned out all breather's and fitted the breather box on the back of the rocker cover
i have also changed the ECU in the fuse box with a new key and black box under the steering column but the car then refused to start...
i have been informed that the lpg kit is fitted and a wire is conected to the throttle possition sensor somewhere but i dare not start looking into the wireing as there are load's in there.....
i am really wanting i suppose is someone who know's about lpg kit's and can point me in the right kind of direction to get it fixed without a mega expense
thanks in advance

is there any other codes coming up????
new ecu has it been setup for alarm and imobiliser & ABS
have you checked all the earths in engine bay.
-
Manual or Auto?
Could well be MAF sensor as this has been known to throw up the TPS fault P1555 i think :-?
-
Yep, and check the brake pedal switch
-
both "My Naff Code Reader" and tech 2 have come up with throtle possition sensor low voltage, i have checked all earth's in the engine bay and they all seem ok to me..
will check the brake pedal switch and also the maf sensor
i forgot to say it's a manual and the car with spanner light is oin the dash and it wont rev over 4.5k rev's..
thaks so far for the advice..finger's crossed i can get it sorted out soon

Classic symtons of cam sensor failing, which will also throw spurious codes P1555 being one of them
-
cam sensor was changed straight away for a genuine new gm one...will see if i can get the actual code that was there from the tech2 guy

All connections OK. As said revving @ 4.5K max is cam sensor
