Fault codes - Please help
I have been chasing a MCSF problem around for the past few months, the car has been into my local garage several times in this period but with no joy.
So I have purchased alfadiag and I have a list of codes that have shown up. It all points to lambda sensors, but there are a couple of cam sensor faults as well which are a bit worrying. My cambelt was only replaced 18months ago and I have only done 12K in that time.
Anyway here they are...
P0155 lambda sensor bank 2 pre cat
P1155 lambda probe heater resistor circuit bank 2 pre cat
P1178 ? (apparently to do with cam sensor)
P0141 lambda sensor bank 1 post cat
p0136 lambda sensor bank 1 post cat above max limit
p1175 self adaptation parameters FRA bank2 (cam sensor?)
P0150 lambda sensor bank 2 pre cat
Any ideas, Id rather get a good idea of what is wrong before I take it somewhere again. The car runs fine. There are no flat spots, although quite rich (fuel consumption is bad). Slightly lumpy idle as well.
Ive changed the bank 2 sensor already and ive replaced the MAF.
Thanks in advance
