Title: Fault code help needed!!
Post by: docksboy on 24 May 2008, 19:30:33

Hi All, after a miserabel 4 months with my 2.6 v6 52 plate auto miggy the bl**dy management light is on yet again.

Had the oil cooler replaced in March, then had the Crank sensor changed in April, had the two rear springs replaced last week.

Done about 260 miles since last in the garage and the mgt light came on again had tech 2 test done for £20 and fault does were showing as follows; P0430 CAT systems below efficency P0335 not present unknown?? P0420 CAT systems bank 1 below efficiency.

Can someone explain what the they mean and if it going to cost me a fortune already forked out close to a grand.

Thanks Guys :'(

First one is to do with the lambda sensor and heating. Second one is to do with the crank PS.

THird one is Catalytic converter, wiring, Heated Oxygen Sensor (HO2S) 2

0335 is crank sensor.  clear it, see if it returns.

precat efficiency is common on 3.2, not seen many 2.6 like it.
