Did a scan on v4-max's (John) cossie at the Kent meet and got 2 codes: P1151 &P1132 (?contradictory). Then checked the data LTFT were both -14 to -18%, TPS 18%. MAF looked OK though John's promised to give it a clean.
But when I replayed the scan I noticed another code had appeared - P0472:
Auxillary Emission Controls: exhaust pressure sensor A: circuit low input.  Can't find any info. I expect the codes are linked.
Any idea what this means?
Also 1132 (bank 1 sensor =rich) and 1151 (bank 2 sensor =lean) seem to contradict each other since all data indicates its should all be rich - unless 1151 is a really old code that's been hanging around - any thoughts?

hi there
the ltft look like a fpr issue.
the p0472 points to the transducer on the egr, i think.
i'd clear the codes and run it for a week or two. see what comes back, if any. but i would keep an eye of the ltft. don't see that going away, but make sure there's no air leak, etc.

Thanks for info Andrew.
Funny that code only appeared whilst I was running the scan though.

hi paul
wiring?  is there a running issue apart from the fueling? maybe try blocking the small vac pipe to the egr for a week or two.
no sure at all, but the ltft were similar to sam's (tintin). fixed with a new fpr, but cat(s) were shot or nearly by there.
