Hello, my name is***** you still getting the P0113 code? Thanks.

Customer: replied 10 months ago.
When I put the new MAF Sensor in I get the 113 code. When the old is in I only get the 174 by itself
Expert:  Dan replied 10 months ago.

It sounds like the new MAF is the problem if you are getting two separate codes. If something else was causing the P0174 code then it should set with both MAF sensors. I would recommend replacing with a new sensor of a different brand. Let me know if you have more questions, thanks.

Customer: replied 10 months ago.
That's not my issue. My issue is the 174 code which was present prior to replacing the MAF
Expert:  Dan replied 10 months ago.

Did you get the 174 code with both sensors?

Customer: replied 10 months ago.
that code is present with both MAF sensors

Does vehicle idle rough or lack power under hard acceleration?

Customer: replied 10 months ago.
Not really. I don't notice any drivability issues at all.
Expert:  Dan replied 10 months ago.

I would recommend replacing the front bank 2 oxygen sensor. If it was fuel related or vacuum leak then you would usually notice a driveability problem. Let me know if you have more questions, thanks.

Customer: replied 10 months ago.
Is there a way to test the oxygen sensor or figure out if it truly is bad? I don't want to just throw money to attempt to fix an issue I want to make sure that is the issue first
Expert:  Dan replied 10 months ago.

If you have scan tool to monitor sensor you can compare signals to the front two and if they aren't the same then replace. Let me know if you have more questions, thanks.

What is its determine a rough idle
Customer: replied 10 months ago.
why when only the rear o2 sensors are off does the 174 code go away
Expert:  Dan replied 10 months ago.

If Idle was rough that could point toward restricted injectors or vacuum leak. When disconnecting rear sensors it disables monitor. Let me know if you have more questions, thanks
