Title: need help please....
Post by: Rich p on 23 June 2010, 00:52:47
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

Rich

Manual or Auto?

Could well be MAF sensor as this has been known to throw up the TPS fault P1555 i think  :-?

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

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