hello everyone,
Here is the issue im having, any advise would be great.
2003 alfa twin spark 2.0L petrol automatic
has check engine light on.
when erase codes light comes back on within seconds.
code causing light p0100 ( air flow meter )
other codes ( all related to o2 sensors )
MAF tested and working perfectly.
wiring all fine.
o2 sensors showing 0 ( nothing ) when car is on.
brand new crank sensor, sparks, all filters, gaskets, maf sensor
local mechanic didnt know much i dont think. told me " im not sure but may be the ecu ill have to take it to test at a cost of around $800"
any help guys
Sorry mate wish I could help. I currently own an 2002 147 2.0 TS manual and am having a lot of issues as well. My advice would be if it's running without too many problems then don't worry too much. My main bearing in my engine has worn out thus creating a constant and rapid clicking noise. To fix it I need an entire rebuild but as it is running fine for now I'm not too worried. Another thing to consider is when one of my spark plugs/ coil packs exploded there was no falt or warning lights being displayed at all so having the lights on may not indicate a mechanical failure.
Sounds like solving this puzzle, could be a job for Bazz.
You need a Mech that is familiar with Alfa Romeos. Sent you a PM, I MAY be of some help. ;)

They should read some voltage.
