My 1.3litre diesel multijet Idea has developed an engine failure, the fault code is PO160. Has anyone any experience of what this code is and how it can be rectified?
the fault code is P0160, not PO160, you shuold have got a small booklet with your codereader that explans all the codes, however there are plenty of places online that tell you generic and manufacturer specific fault code meanings.
this tells you that it is your second (aka downstram) lambda sensor that has no signal at all. usually that means it is comepltey dead or there is a wiring fault.
a1ant's suggestion that the wiring connector may be the problem is also my first thought. if in doubt change the lambda, but make sure you change the right one.
