can no longer automatically adjust the mixture between air and fuel. Code P0172 applies to Bank 1 and P0175 applies to Bank 2. Code P0175 mainly applies to V6 or V8 engines because 4-cylinder engines generally have only one bank, though there are a few exceptions.

I was having P0171 & P0174 codes for Air/fuel to lean. Saw where Mass Airflo

All was normal then the check engine light came on and the engine began to r

un roughly. The OBD codes that are stored are P0172 and P0175 System too rich on both bank 1 and 2. What should I be looking at as the probable cause of this issue. Thank you in advance.

Ok here is the obd data at idle. Also the p0172 and p0175 came back along wi

th p0300. Also if you think it is the fuel injector what make do you think I should put in and since i am replacing stuff should i also replace the fuel regulator. Motor has a 157000 on it. Thanks

They were replaced and the car is now returning codes p0172 and p0175 which

are the only 2 codes coming up when the check engine light came on. My question is if the dealer sold me the incorrect oxygen sensors could this cause the computer to incorrectly set the p0172 and p0175 rich fuel mixture codes.

So, when clearing the codes the car will run fine for a short period of time

(like 15 days) then the same codes pop again. P0101, P0172. I think that the reason behind this is ECM learning the LTFT so when clearing codes the computer will reset LTFT and it needs some time to get -20 reading again and throw the P0172.

So your car’s CEL (always check Engine Light) is on and also you had the c

odes scanned at a local parts shop. (Or maybe used your own OBD scanner to extract the car faults). Your car or truck has either a P0171, P0174 lean fault code or both stored in the pc, these codes derive from Oxygen Sensor (O-2) readings.
