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.
The P0031 code is a result of the bank 1 HO2S1 (pre catalytic converter heated oxygen sensor) heating element having low voltage. Heated O2 sensors have a seperate heater inside the sensor to get them to operating temperature quickly.Oct 1, 2018
https://www.obd-codes.com/p0031 Check for a fuse bing blown , Heater circuit shorted in O2 sensor blowing the fuse , maybe . You don't say what make , model an year vehicle an engine size .
http://www.autocodes.com/popular_codes_make.php?make=DODGE, try to look up the codes under the autocodes.com, this site can help you find the code and give you help to fix it, also look for the ground wires and they are grounded to the engine and body
code p0037 refers to heated oxygen sensor(HO2S) 2 bank 1 heater control-circuit low===causes ---wiring short to ground--HO2S---ECM I would replace the oxygen sensor and check that the wiring is not shorting out.
All 3 of these Codes have to do with the O2 devices. Some are saying the heating elements are returning low signals. These elements are built inside the O2 sensors and are designed to make your vehicle get out of "rich" mode faster.
Bank2 sensor1, Bank1 sensor1, Bank1 sensor2. Check your connections and the wiring leading to these parts.
You may need to replace these O2 sensors if the wires are good.
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.
