Hi guys done a fault code check on my subaru impreza uk and it says 32 and 23, looking into it is that my lambda sensor and maf sensor.? My lambda sensor is not there tho because its been decated so i can count that out, does this mean my maf sensor is definatley buggered. The car as been running **** last few days spluttering and kangarooing and no power for a few seconds when i put foot down then it kicks in.

 

i would say the maf could be causing the lamba sensor fault code? or vise versa?
also what colour maf is it?

 

The car needs a lambda sensor whether it's been decatted or not! I think you'll find that's why you have a fault code. I'd plug one in pronto if I were you.
The maf may well be faulty, you'd need someone with a bit of knowledge and a voltmeter to check it out.

 

Were do i plug 1 in when its been decated and whats the voltmeter for to check the maf if so what is the right voltage.

 

Can u clean the MAF sensor ive read a few threads of people with similar problems and cleaning it.

 

yes you can clean the maf, you can also repair the orange mafs sensors ( it think?)
heres how to check a maf sensor...

i presume you put the red probe to the live on the maf, the black probe to earth on the battery. switch the volt meter to the 20v setting.

 

+1 there should be one in the decat downpipe should they not?

 

My exhaust is straight through from engine bay to back box and i cant see anywere for a sensor to go.

 

hi mate mine has the same problem and also has a straight through exhaust !
did u get this prob sorted ?

 

yes mate i did a fault code check with wires under steering column and it showed code 32 lambda sensor, so with the help of people on this forum i changed lambda sensor and problem solved. Go here mate this should help you. http://www.scoobypedia.co.uk/index.p...eadingECUCodes
