Hi I found a site actually in the Uk.Called citroen-owners-club.co.uk on there I found this info
Intake Air Temperature Sensor Open/Short To Positive. P1161
As For fuel trims+ means adding fuel - means taking away so if its - Taking away you have to much and If its adding you have to little .High fuel trim would suggest a vaccum leak for example, to much air. Down load that escan program and go through that one in demo mode it has examples, video all just there for the looking.Will give you a feeling about what this Escan can do. Hope this helps you.
Hi hefaus
Thanks for that much appreciated
Looking forward to Feburary 2010 for the vantage pro to be available in the UK
Had a Citroen C3 1.4 MPI year 2003 in the other day, customer complained that the instrument display EML came on and the instrument display engine temperature gauge started to read low?
I put the Solus pro scanner onto the vehicle and read the fault codes which came back with set code P1161 - Throttle Position Copy?
I said well it must be something to do with the throttle pedal or throttle butterfly housing, but what would that have to do with the engine temperature gauge reading low?
Some people have complained that the scanners do not pick up the correct fault codes when problems arise, my experience is new with the scanner?
I road tested the car up to 70 MPH constant and graphed the data, to me the graphs seem to be pointing towards a fuel related fault, the lambda 1 before the CAT momentarily looses the switching signal and at the same time, the fuel trim (STFT) as the (LTFT) was not used on this model moved upto +20%, now my understanding was that negative fuel trim increased fuel but this was shown on the (LTFT) which is not used, so does the (STFT) on this model having two graphs (STFT)s indicate that both graphs showing +20% is reducing the fuel supply, the reason I ask now is because the front lambda momentarily stops reading, and lambda 2 after the cat which is reading but alot less than lambda 1 is also momentarily not reading at the same point on the graph displays?
The type of graph used for the coolant sensor indicates a continuous read out but as would be expected of a vehicle on the road at speed, the signal does slightly drop down lower on the graph scale.
Wished I knew how to upload them for you to see?
What do you think
