I bought the Actron CP9125 and got these 4 codes.

P0174 P0102 P0112 and P1111.

Can someone help figure my problem out. It appears to be air flow related I think but could use some advice.

2003 S-Type 8 cyl

THX

 

P0102 = Mass or volume air flow circuit low input.
P0112 = Intake air temperature sensor 1 circuit low input.
P0174 = System too lean (Bank 2).
P1111 = System pass.

Those codes have been stored, but the system pass indicates they haven't occurred very recently. Try a reset and see if they come back.

 

Here are some old TSBs that might help with your diagnosis

Cool thanks.

I posted same thread on S-Type and stated I erased the codes and replaced cheapy air filter with original Jag. The errors or lights have not come back so far.

Reader says P1000 pending.

So we'll keep an eye on it.
