Old question that must have been resurrected by spam, but I fixed the dreadful written English tossed in some CAPS and a few SPACES! It looks pretty now.

All questions need full 'year make model', rather than 'year make, engine size'.

Anyway, there is this thing called Google. It knows everything. Here is your first code. Just copy and paste the others in and press enter.

I am getting two codes on my 2004 Volvo S-40 I. P0031 and P0037.
I have also changed both oxygen sensors with OME sensors. What do I look for next

code P0031 - O2 B1 S1 heater circuit low. code P0037 - O2 B1 S2 heater circuit low.

What year is the vehicle ? Codes P0031 37

these codes are o2 sensor related need to get dealership to check out

Have you cleared the codes at least once?
The new o2 sensors should have removed all those codes.The sensor closest to the engine b1s1 may be defective.Check wiring and plug to that one closely.
